We easily select the height of the table in the kitchen using the scientific method. What should be the normal height of a computer desk? Standard height of a desk in an office

Computer desks today are indispensable attributes of every home. Such interior items have gained such wide distribution and enviable popularity due to the fact that life modern man is inextricably linked with computer equipment, which requires a separate place.

However, the choice of high-quality computer desks largely depends not only on their configuration and design, but also on their size.

Peculiarities

Nowadays without computer desk not enough. These pieces of furniture are special in that they can be used in a wide variety of settings. It could be like city apartment or a private house, and a small or large office, as well as a government or entertainment institution. Thanks to multitasking, such furniture can be safely called universal.

Moreover, such designs are often located in both adults and children’s bedrooms, because today even the youngest users easily master the appropriate technology. A properly selected computer desk is perfect for work, play and relaxation. These interior items are multifunctional, since they can be used not only for working on a laptop or desktop PC.

Often, models with large and spacious countertops are divided into two halves. One of them is dedicated directly to the computer, and the second becomes a writing area. As a rule, such tables are of impressive size, but they are very convenient to use.

Such widespread and sought-after furniture finds its place in almost any room of the home. This can be not only a serious study or a schoolchild’s bedroom, but also a living room, a library and even a kitchen (if we are talking about a studio apartment).

Working and studying at such a table should be as convenient as possible, which is why modern furniture factories They produce many options with very different structures, as well as different lengths, heights and widths.

These parameters play one of the critical roles in choosing the appropriate computer desk model.

The fact is that when working on a structure of inappropriate dimensions, the user will feel very uncomfortable and uncomfortable. Moreover, constant use of such tables can cause significant harm to human health. So, working behind a model that is too low, you will have to constantly bend over and lean your body forward, which over time can lead to serious curvature of the spine and stooping, not to mention aching pain, which can become your constant companions.

You need to take the dimensions of the computer desk you plan to buy for your child no less seriously. Here it is very important to pay attention not only to the width and length of the tabletop, but also to the height of the structure as a whole. If you do not want to harm the growing body, then the computer desk for it must be selected correctly.

Of course, the choice of furniture of certain dimensions largely depends on how many items you plan to place on it. If there are not so many of them, then it is quite possible to get by with a compact model with no big table Yeshnitsa.

If you are looking for a more capacious and spacious option, then its dimensions should be appropriate.

How to calculate all sizes?

If you want to know the correct parameters of a computer desk, then you should turn to a simple mathematical formula that many buyers use today when choosing furniture:

To independently calculate the height of a computer desk, you need to do the following: height (in centimeters) x 75 cm (standard height of PC tables) / 175 cm = height of the structure

The width of a computer desk should not be too small. It is recommended to add another 30-40 cm to the specific parameter of a particular tabletop. This way, you will provide extra space for bedside tables;
Minimum correct depth computer model without add-ons it is 45 cm. Of course, if the design has other additional components, then this figure can be greater, for example, 60 cm. The optimal depth of such furniture primarily depends on its structure and configuration.

Standards and popular dimensions

It is recommended to consider the standard dimensions of tables for PCs and laptops, starting from the most compact models. With the exception of height, other parameters can be changed without any restrictions.

As for height, it plays one of the most important roles in the design of such furniture. An incorrectly selected option can harm not only the spine, but also the user's eyesight, since the monitor on such a model will be at the wrong height. Mainly selection correct option depends on the position in which the person will sit behind it.

Experts say that while working at a computer desk, the body should remain in this position:

back – straight;
forearms – in a relaxed state;
shoulders – not raised or tense;
muscles are also relaxed;
the legs should be level and placed on a special stand, a shelf under the tabletop, or simply on the floor.

The classic table height for computer equipment is 750 mm (75 cm). It is calculated based on the average height of representatives of both sexes. Thus, the average height of men is 175 cm, and that of women is 162 cm.

If the user’s height is very small (150 cm) or, conversely, too impressive (190 cm), then in such cases the following solutions will be a real salvation:

height-adjustable chairs;
order design by custom sizes;
tabletop with adjustable function.

However, the width of the structure depends on several important factors:

the minimum is 60-70 cm, and the maximum is 80-95 cm;
the compartment for the system unit should occupy at least 20-30 cm;
First, set aside a free space to place the cabinet and add another 30-40, 45 cm to the entire structure;
Products with a corner structure must have a rotating tabletop space of 50-60 cm.

Another important parameter of a computer desk is its depth. The main dimensions of the entire structure as a whole largely depend on it.

When calculating this part, the following nuances should be taken into account:

tables that do not have add-ons, as a rule, have a depth of at least 45 cm;
structures that contain additional superstructures have a depth of 60-70 cm;
corner specimens equipped with shelves most often have a depth exceeding 85 or 90 cm.

Non-standard solutions

Many consumers are faced with the fact that not a single computer desk model from the standard range suits them. In such cases, you should not panic or get upset. Fortunately, today many manufacturers offer custom furniture manufacturing services. So, you can come with your sketch and measurements in order to order the ideal design with optimal dimensions. Of course, such products often cost more than popular display options, but in this case the end justifies the means, because as a result you will get the most convenient and comfortable computer desk.

In addition, multifunctional designs with adjustment are very popular today. They are in enviable demand not only because they can be easily adjusted to fit a person of any height and configuration, but also because they can be selected even for a compact home and save free space.

The table supports, tabletops themselves, and monitor stands are adjustable. If you combine such furniture with comfortable adjustable chairs, the result is a universal tandem that all family members can work behind, adjusting the functional designs to suit themselves each time.

Functional models

Modern manufacturers produce a great variety of computer desks with different structures and functional components. Let's take a closer look at the most popular and sought-after options that are found in many homes today:

Direct. These products are among the most popular, since they were the first on the furniture market. Most of these designs have spacious rectangular countertops. They can be placed along a free wall in the room, thereby freeing up free space in the central part. It is recommended to place straight tables so that they do not block the passage and do not interfere with free movement in the room, since the presence sharp corners such furniture can lead to painful blows;

Corner. These models are the second most popular. Their main advantage is that they save space in the room, since they can be placed in a free corner. In addition, in them, as a rule, the system unit can be moved a little further, without thereby cluttering the workspace. All items located on the corner tabletop always remain accessible;

Diagonal. Today, such models are enviably popular, as they look original and are very convenient to use, which is noted by many buyers who have forked out money for such designs. At these tables, the user can sit diagonally, with his face directed toward the corner. Often miniature mini-tables have a similar structure. Their disadvantage is considered to be insufficient functionality. Bedside tables, as a rule, are present under the main covering of these models, and pull-out elements are completely absent.

Diagonal designs most often have small countertops. The length of the side part in them can be only 60-70 cm, but there are also more compact options. These tables are rarely equipped with add-ons. Much more often you can find small bedside tables with drawers in them.

Diagonal-perpendicular. Sitting at such computer desks, the user's face may be directed to a corner, but he will always have the opportunity to turn towards the wall or towards the window opening (perpendicular). These options most often have considerable dimensions, so it is not recommended to buy them for small homes. However, it is worth noting that diagonally perpendicular tables differ in functionality. They often have useful compartments with drawers, roll-out or built-in cabinets, add-on shelves and other practical details;

Rack. Today, well-thought-out designs of computer desks that include additional shelving are very popular. Most often, such options have considerable dimensions, but they should not frighten or repel the buyer. The fact is that having such furniture in your room, you can save on buying a box or bookshelves, because you will already have a shelving unit combined with a computer desk.

Examples in the interior

Today, every consumer has the opportunity to choose the ideal computer desk that will fit seamlessly into his home. It doesn’t matter at all what style the furnishings are in. It can be both an eternal classic and a shocking avant-garde.

Very popular today corner structures computer tables. They often combine several different colors at once. For example, the main body can be snow-white, and the drawer doors can be dark chocolate. Such a model will look interesting, even if it has compact dimensions.

You can place such a table in a rough light gray room in the loft style with a milky gray parquet floor, laconic wall paintings and a dark round carpet on the floor.

For the convenience of working at the table, you need to take into account its height. This parameter affects the comfort of using furniture. Standard height The table should be suitable for the average performance of adults and children. Moreover, this parameter is different for each type of furniture.

Purpose

The main thing in furniture is its parameters. Why is table height important? This indicator can provide ease of use. As well as protection against spinal disorders. The height of the desktop plays an important role. This determines the comfort required by the position of the body, especially the back.

If the furniture is not suitable, then the person needs to lean forward and slouch while working. This causes curvature of the spine, as well as discomfort in the back. Therefore, it is important to choose the appropriate table height for adults and children. But it should be borne in mind that for each type of structure, taking into account its purpose, the parameters are different.

Kitchen

The height of the kitchen table is determined by the person’s parameters. The greater the height, the higher the working surface should be. In this case, the furniture will be comfortable. To determine the optimal height kitchen table rules used:

With a height of up to 150 cm, the design should have parameters within 75-76 cm.
At 150-160 cm, a height of 80-82 cm from the floor is more suitable.
Indicators of 160-180 cm are considered the general standard. They are taken into account by many companies when creating furniture products. In this case, the parameter can be 87-90 cm. This is the standard table height, since it will be convenient for men and women.
If the height is higher than standard parameters, then the furniture is created to order. At 185-200 cm, there will be 1 meter from the floor to the tabletop.

It is important that the furniture is comfortable for the whole family. Since it is not possible to select a design for each parameter, therefore the average is calculated. For example, if the wife’s height is 150 cm, and the husband’s is 190 cm, then the average is 170 cm. And for this you need a table 85-87 cm in height. And since women usually spend more time in the kitchen, it is better to choose 80 cm.

Writing

The height of desks for children and adults is different. This should be taken into account when purchasing a structure. If height-adjustable tables are created for children, then for adults everything is different. It is important to take into account body type, size, and height. You need to choose furniture based on these parameters.

In addition to height, length and width are taken into account. They must meet standards. When these indicators are lower, inconveniences are felt that negatively affect the condition. musculoskeletal system. Comfort is determined by the height of the desktop and other dimensions. According to the “Modulor”, created by the architect and designer Le Corbusier, the following proportions apply:

Since the average height of people on earth is about 175-183 cm, the standard height of a writing desk is 700-800 mm.
For 150-160 cm it is better to choose 60 cm.
If you are 190-200 cm tall, you need to order a desk height of 85-90 cm.

These rules are used all over the world. Taking them into account, it will be possible to select suitable product, which will be comfortable to work with.

Computer

A suitable computer desk height will allow you to work comfortably for long periods of time. When the parameter is insufficient, the person leans forward, which greatly strains the back. And at higher rates, the person sitting raises his head up, which negatively affects the condition of the back.

There are rules that must be taken into account when choosing computer furniture:

When sitting at a table, your back should be straight and your shoulders should be straightened to the sides.
The forearms should be placed on the surface.
It is important that the shoulder girdle is not raised.
The norm is location work surface in the solar plexus area.
Your legs should be bent at a right angle, they should be on the floor.

If you follow these rules, you will be able to prevent problems with the spine. A person will not have curvature or deformation, which usually lead to serious illnesses. The height of the computer desk is determined by height. Usually it is 75 cm, which is designed for a height of 170-172 cm. For others, such a product will be inconvenient. Then you need to order a design.

Dining

The height of the dining table should be comfortable for everyone so that there is no discomfort while eating. When sitting at such furniture, the body should feel relaxed, it should rest. When choosing the height of the dining table, height is taken into account.

For convenience, you need a size of 700-750 mm. This parameter is optimal, it is chosen with a height of 165 cm. The average height of furniture is 72-78 cm. To calculate the appropriate option, the formula is used: furniture height = height * 75/165 (75 cm is the height of the structure, 165 is the average parameter of a person). For example, with a height of 170 cm, the calculation will be as follows: 170*75/165=77.3.

Children's

Correct height children's table will allow you to work comfortably. Then there will be no strong tension on your back. For children, furniture must be chosen especially carefully, otherwise unsuitable designs lead to curvature of the spine. But they have to spend a lot of time at the table.

Height is required to determine height. If a product is selected for a first-grader or teenager, then the following parameters should be taken into account:

With a height of up to 85 cm – 34 cm.
85-100 – 40 cm.
100-115 – 46.
115-130 – 52.
130-145 – 58.
145-153 – 64.
154-161 – 67.
162-170 – 71.

Suitable parameters ensure the full development of the child. It is also worth considering that a growing organism requires suitable conditions for comfort. When choosing furniture for a child, you need to focus on the following points:

The feet should be on the floor, and the shin and thigh should form a right angle.
The required depth of the chair is set as follows: the seat of the chair should not dig into the popliteal joints.
There should be 10-15 cm or more between the knees and the tabletop.
The distance from the eyes to the surface of the structure should be from the tips of the fingers to the elbow.

It is necessary to choose a suitable chair for the table so that the child’s classes are comfortable. In addition to height, you need to pay attention to width, shape, and design of structures. The material and the presence of original parts are also important. Chairs of a height suitable for comfortable use are often sold in sets with tables. The main thing is to use them as intended.

Selection rules

Although many different parameters are taken into account when buying furniture, size should still be the main thing. And this applies to any type of table:

If you plan to choose a kitchen set for cooking, then it is better to buy 80-85 cm. This indicator is standard, so there will be no difficulties with the search. In addition, such a product will be comfortable for people with a height of 1.5-2 meters.
If a written design is required, and the height is greater or less than average, then it is advisable to order furniture according to the required parameters. Dimensions should be set according to the formula: height*75/165 cm.
It is important to know when choosing chairs - best height is 42 cm. Tall people need 45, and small ones need 40.
If you are buying a product for a child, you need to calculate it especially carefully. Adjustable models work great.

Solving non-standard situations

Height is especially important when choosing furniture for the whole family. Non-standard cases are solved in the following ways:

The size of the chair can be adjusted. There are many chairs sold in stores and markets that can be adjusted in height. This will allow you to sit comfortably at the table. But then there may be inconvenience with the placement of the legs. And this negatively affects health.
Manufacturing of furniture to order. In this situation, it is preferable to focus on the growth of an individual in the family. You can determine the average. A difference of a few centimeters will not be visible. But you can get the desired result only with a small difference in height. Before production, a drawing must be created.
You can choose a table with an adjustable top. Such products are usually created for schoolchildren.

These techniques allow you to create furniture that is comfortable for the whole family. The best solution The design will be made to order or independently. The advantage of the method is considered to be budget savings, and it also becomes possible to create a comfortable product.

Adjustable height

In addition to classic products, there are tables that are height adjustable. These are mechanical modules or transformers. They often have X-shaped supports with which you can set this parameter. But there may be a retractable or electronic mechanism.

An excellent choice would be coffee table, which can become lunchtime. The advantages of furniture include:

Comfort for the whole family - you can adapt to children and adults.
Compact and space saving due to multifunctionality.
Practicality and the ability to be placed anywhere in the room.

The disadvantage of height-adjustable tables is their high price and low load that the product can withstand - approximately 30-45 kg.

Consequences of the wrong choice

Furniture that is incorrectly selected in height creates tension, discomfort, and fatigue. This applies to tables for different occasions. In the kitchen, this design also causes a lot of inconvenience. About 40 muscles work when slicing food. If workplace higher, the load increases noticeably, and if lower, this causes rapid fatigue.

A suitable table height eliminates back problems and diseases associated with this phenomenon. Knowing the height and calculation rules, you will be able to choose suitable furniture.

Operator's workplace. What should a desktop look like? Will you eat?
(Windows/Desktop)
Even the most notorious idealist will not argue that furniture is exclusively an object created by Man. In the Gardens of Eden, such an object could only serve as the famous Tree of Knowledge, the furniture-derived properties of which were prevented by certain circumstances for Adam and Eve.
When placing a PC as a desktop, a type (!) ordinary desk is often used (apparently, it is called that because there is a PC on it). Modern table owes its appearance to the style that appeared at the beginning of the 20th century. At the heart of this new movement in European architecture and the furniture industry was the aesthetics of expediency, which presupposed rational, strictly utilitarian forms. In accordance with this pragmatic attitude, the design of the table should ensure optimal placement of the equipment used on the working surface, taking into account its quantity and design features(size of PC, keyboard, music stand, etc.), nature of the work performed.

At the workplace, in addition to the monitor and controls, the placement of which was described in sufficient detail earlier, documentation must be located, records can be kept, other technical means can be used, therefore, in order not to cause frequent re-accommodation of the eyes, items of permanent use at the PC operator’s workplace and the visual elements of the information model should be approximately the same distance from the eyes. Working surfaces must have the following minimum dimensions:
- minimum width countertops - 500 mm;
- free area for notes - 100x200 mm, and for more detailed notes - 300x400 mm;
- plane to ensure the execution of drawing and graphic work - 450x650 mm.
The shape of the working surface should be determined taking into account the nature of the work being performed. It can be rectangular, have a cutout for the worker’s body, recesses or other surfaces for office equipment, etc. (less dogmatism!). If necessary, you can even install armrests on the work surface (or a headrest if you want to sleep - just kidding!). If increased accuracy is required during work and, accordingly, it is necessary to fix the position of the body and hands, as additional measure soft upholstery can be used on the front edge of the table.

The height of the working surface of the table for adult users who are mainly engaged in typing information should be adjusted within the range of 680–800 mm; in the absence of such a possibility, the height of the working surface of the table, in accordance with the anthropometric characteristics of the domestic user, should be 725 mm. At the same time, as accurately calculated at the very Lately European ergonomists, the monitor screen should be located 28 cm below eye level. In addition, if you want to create a workplace exclusively for yourself and, accordingly, taking into account your type of activity, you should keep in mind that, in principle, the height of the working surface should vary depending on the types of work performed (see Fig. 1).

Rice. 1. Nomogram depending on the height of the working surface for different types work performed in a sitting position, depending on the height of the person: type 1 - very precise work (use of positioning devices with accuracy on the verge of the capabilities of the human visual apparatus, for example, control of optical instruments); type 2 - precision work (use of positioning devices with high accuracy, for example, for graphic work); type 3 - light work that does not require high precision, but requires the use of positioning devices, for example, to select information; type 4 - work on typing text information.

The modular dimensions of the working surface of a PC table, on the basis of which the design dimensions should be calculated, should be considered: width 800, 1000, 1200 and 1400 mm; depths of 800 and 1000 mm with an unregulated height of 725 mm.
The work desk must have legroom with a height of at least 600 mm, a width of at least 500 mm, a depth at knee level of at least 450 mm and a depth of at least 650 mm at the level of outstretched legs.
When working with text documents, the workplace should be equipped with an easily movable music stand for them.
When organizing workplaces for working in a standing position, for example, on technological equipment that includes PCs (computer-controlled machines, robotic and technological complexes, flexible automated production, dispatch control panels, etc.), the following should be provided:
- a space in depth of at least 850 mm, taking into account protruding parts of the equipment for the location of a human operator;
- foot space with a depth and height of at least 150 mm and a width of at least 530 mm;
- arrangement of information input/output devices to ensure optimal screen visibility;
- easy reach of organs manual control in the motor field zone: in height - 900-1300 mm, in depth - 400-500 mm;
- location of the PC screen in the work area, providing ease of visual observation in vertical plane at an angle of ±30° from the operator’s normal line of sight, as well as ease of use of the PC (input/output of information when adjusting basic parameters technological process, debugging programs, etc.) simultaneously with the execution of basic production operations(monitoring the processing area on a computer-controlled machine, when servicing a robotic technological complex, etc.). Here, as in the case of a sitting workstation, the height of the working surface should vary depending on the type of work performed (see Fig. 2).

Rice. 2. Nomogram of the dependence of the height of the working surface for different types of work performed in a standing position on human height: type 1 - constant work with a PC with visual inspection of other technical means; type 2 - predominant work with a PC while simultaneously servicing other electronic devices; type 3 - occasional work with a PC with constant work using physical effort.

Keep your workspace clear. At IBM, for example, it is customary to clear desks of papers every evening before leaving work. Sanctions are applied to violators.
Jobs for students of secondary and higher educational institutions have their own specifics. Rooms for classes using a PC must be equipped with single tables designed for working on a PC.
The design of a single desk for working with a PC should include:
- two separate surfaces: one - horizontal for placing a PC with continuously adjustable height within the range of 520–760 mm and the second - for a keyboard with continuously adjustable height and tilt angle from 0° to 15° with reliable fixation in the optimal working position (12 °–15°), which helps students maintain the correct working posture, without sharply tilting the head forward;
- the width of the surfaces for the PC and keyboard is at least 750 mm (the width of both surfaces must be the same) and the depth is at least 550 mm;
- supporting the surfaces for the PC and the keyboard on a riser in which the power supply wires and the local network cable should be located. The base of the riser should be combined with the footrest;
- no drawers;
- increasing the width of surfaces up to 1200 mm when equipping the workplace with a printer.
The height of the edge of the table facing the person working with the PC and the height of the legroom should correspond to the height of students or students wearing shoes (Table 1).

Table 1. Height of a single table for studying with a PC
Height of students wearing shoes, cm	Height above the floor, mm
Height of students wearing shoes, cm	table surface	legroom, no less
116-130	520	400
131-145	580	520
146-160	640	580
161-175	700	640
above 175	760	700
Note. The width and depth of the footwell should be the same as for an adult user.

With a vertically positioned PC screen, eye level should be at the center or 2/3 of the height of the screen. The line of sight should be perpendicular to the plane of the screen and its optimal deviation from the perpendicular passing through the center of the screen in the vertical plane should not exceed ±5°, acceptable - ±10°.
Premises where PC-based gaming systems for preschool children are installed must be equipped with single tables.
The design of a single table with gaming complexes should consist of two parts or tables connected together: a video monitor is located on one surface of the table, and a keyboard on the other. In addition, the design of the PC table should include:
- smooth and easy height adjustment with reliable fixation of the horizontal surface for a video monitor within the range of 460–520 mm with a depth of at least 550 mm and a width of at least 600 mm;
- the ability to smoothly and easily change the angle of the keyboard surface from 0° to 10° with reliable fixation;
- the width and depth of the surface under the keyboard must be at least 600 mm;
- a flat table surface without indentations for the keyboard;
- no drawers;
- legroom under the table above the floor is at least 400 mm in height;
- the width of the legroom is determined by the design of the table.

What to sit on
You won't be able to sit out... me!
(Ilya Muromets)
The PC operator's work chair (chair) should include the following basic elements: seat, backrest and armrests. As additional elements There may be a headrest and a footrest. It is advisable not to limit the mobility of the chair relative to the floor or other surface on which it is installed (a podium, for example).
The design of the chair should ensure the maintenance of a physiologically rational working posture when working on a PC, allow you to change the posture in order to reduce the static tension of the muscles of the cervico-brachial region and back to prevent the development of fatigue.
As a result of incorrect working posture, occupational diseases of the musculoskeletal system can also develop, these are:
- osteochondrosis of the lumbosacral spine (stiffness and pain in the back and lower back) - as a result of a static, uncomfortable posture;
- osteochondrosis of the cervical and thoracic spine (tension and pain in the neck and back) - occurs as a result of working with incorrect posture if you are constantly slouching, hunching, or, conversely, stretching your neck;
- superior outlet syndrome chest(acroparesthesia - tingling sensation and numbness of the hands) - overstrain of the muscles of the neck, shoulder and chest, leading to deterioration of blood supply and conduction of nerve impulses;
- shoulder impingement (sharp pain in the shoulder joint) - the tendons or ligaments of the shoulder joint are compressed or pinched between the head of the humerus and the process of the scapula;
- scoliosis (lateral curvature of the spine) - too hard or too soft seat, discrepancy between the height of the chair and the anthropometric parameters of the user;
- hemorrhoids (an increase in the cavernous bodies of the rectum, complicated by bleeding) - occurs as a result of a sedentary lifestyle, improper fit, seat design.
The chair should be lifting and swivel and adjustable in height and angle of inclination of the seat and back, as well as the distance of the back from the front edge of the seat, while the adjustment of each parameter should be independent, easy to carry out and have a secure fit.
Its design should provide:
- adjustment of the height of the seat surface within 400-550 mm (from 5 to 95 percentile) and tilt angles forward up to 15° and back up to 5°;
- possibility of rotation 180°–360° (around the vertical axis supporting structure chairs with fixation in the desired position);
- the width and depth of the seat surface is at least 400 mm (calculated for the 95th percentile), wider is better, since the not too limited width of the seat allows you to periodically change your posture;
- seat surface with rounded front edge6, radius of curvature not less than 10 mm;
- the height of the back support surface is 300 ± 20 mm, the width is at least 380 mm and the radius of curvature of the horizontal plane is 400 mm (back height parameters are given for the most common "household" type, but there are also low - lumbar and high backs);
- backrest tilt angle in the vertical plane within adjustable limits 95°–110°;
- adjustment of the backrest distance from the front edge of the seat within 260–400 mm (the minimum size is determined based on 2/3 of the value of the anthropometric feature "seat back-popliteal angle" for the 95th percentile);
- stationary or removable armrests with a length of at least 250 mm and a width of 50–70 mm;
- adjustable armrest angle 0°–20 (non-adjustable - 0°–5°);
- adjustment of the armrests in height above the seat within 230±30 mm and the internal distance between the armrests within 350-500 mm (from 50 to 95 percentile).
Note. Percentile calculation of chair parameters is used when designing a chair for a specific group of users, for example, if the management of your company is seriously concerned about the health of its employees. Currently, it is also practiced to exclusively design chairs according to the anthropometric parameters of the individual user - this is if the management of your company is seriously concerned about their own health.

The surface of the seat, back and other elements of the chair (armchair) should be semi-soft, with a non-slip, non-electrifying, moisture-repellent and breathable coating, ensuring easy cleaning from contamination. The seat upholstery settlement of work chairs should be within 25–30 mm. Chairs intended for long-term rest may have a slightly greater draft - 30–40 mm. The seat surface can be flat, inclined 0°–5°, or profiled. The profiling is created by two angles of inclination of the seat surface - front a, equal to 4°–5°, and rear b, equal to 10°–15°. The apexes of the corners are located on a line distant from the rear edge of the seat surface by 1/3 of its depth, if its value does not exceed 450 mm and by 150 mm in other cases. The seat profiling should not be more precise. So, in 1927, the more famous, although in other guises, architect Le Corbusier was somewhat embarrassed when he designed original form furniture for sitting and lying position. In the bending of the surface stretched over a metal frame, the parameters of a reclining human figure were carefully taken into account. However, it is known from ergonomics that finding body elements, even in a comfortable, but static position, leads to fatigue. Therefore, sitting on this semblance of a chaise longue, which did not facilitate changing positions, was extremely uncomfortable.
There are objective methods for determining the degree of comfort of a seat, in particular, taking actograms - recording involuntary movements or changes in the position of the operator’s body relative to the chair. The operator must be in a state of rest (waiting for a signal). Information about the operator's condition is obtained from strain gauges mounted on a metal plate under the chair's seat. IN general case in the actogram there are low-amplitude, medium-amplitude and high-amplitude (turns of the body, change of position) oscillations. For medium-amplitude oscillations, the dependence of their frequency on the state of the human operator is established. In the normal state, this frequency is in the range of 5–12 oscillations per minute, which characterizes the most efficient mode of operation. With a decrease in the level of wakefulness (falling asleep), which characterizes a too comfortable level, leading to a loss of working capacity, the frequency decreases to 0–5 oscillations per minute. But in a state of inconvenience, fatigue, the frequency becomes more than 12 vibrations per minute.
By the way, instead of achieving comfort, sometimes completely opposite tasks may arise. For example, it was necessary to create an ergonomic booth for long-distance negotiations. It would seem that everything is clear - make a comfortable workplace and consider the task completed. But an analysis of the goal tree showed that for such a telephone booth, what is more important is not attracting customers with comfort (when they don’t even want to leave), but, on the contrary, their more frequent turnover. And so chairs were offered with smooth surface, slightly tilted forward. A person on such a seat feels comfortable enough to carry on a conversation, but he is prevented from talking for a long time by constantly sliding off the chair.
Another example. The use of highly comfortable chairs does not necessarily lead to positive results. It is known that such a danger as falling asleep during a long trip in a car appeared relatively recently and was completely unusual for drivers of a semi.

The workplace must be equipped with a footrest with a width of at least 300 mm, a depth of at least 400 mm, height adjustment up to 150 mm and an inclination angle of the supporting surface of the stand up to 20°. The surface of the stand should be corrugated and have a rim 10 mm high along the front edge.
In the design of the chair, parameters such as the height of the seat surface, the angle of the backrest, the height of the backrest, the height of the armrests, the angle of the armrests, the height of the footrest, the angle of the footrest must be adjusted without the use of additional tools. A person notices a change in seat height by 8-10 mm or a backrest tilt of 1-2°; accordingly, the step of changing these parameters of the chair should be within such limits.
Working chairs (chairs) for students of secondary and higher educational institutions must correspond to the height of students or students wearing shoes (Table 2).

The computer desk appeared only a little later than the PC. It quickly became clear that working on a keyboard is not the same as working on typewriter and requires a completely different hand position. And then the computer had a variety of peripherals, and place them on regular table turned out to be impossible.

The computer desk is calculated based on the features of technology control and its characteristics.

Which is better: a desk or a computer desk?

The basic structure of a desk and a computer desk is the same - a horizontal surface and support in the form of legs or sides. But the ways of organizing this space and the items it fills are different.

When working with documents or books, the latter are placed on the tabletop. A person reading a book at a table lowers his gaze by 45–50 degrees, which means he sits with his head and even his body tilted to reduce the load on his neck.
When working with a computer, his direct gaze should rest on the top edge of the monitor, and his gaze directed to the center of the screen should deviate from a straight line by 0-20 degrees. In this case, the distance to the monitor should be within 50–75 cm. This condition requires a higher, but at the same time, higher position of the monitor if its dimensions are small. This is where the display stand often appears on products. The presence of this device and its height depend on the size of the screen and the depth of the tabletop. This value for computer desks varies widely and can be much less than for a comfortable desk.
When working with paper documents, the writer's elbows are on the table surface. Therefore, the tabletop must have sufficient depth and width. The situation is completely different with working on the keyboard. If you install it on a surface of normal height - 75–78 cm, then your elbows will be suspended and your wrists will be raised. This leads to poor circulation, stress on joints and rapid fatigue.
The keyboard at the computer desk is placed on a special shelf much lower - at a distance of 50–70 cm from direct view, that is, in the abdomen area. In this case, the elbows also remain suspended, but the wrists are in a straight line from the joints, which relieves the load. There is no need for a shelf only when the main work is not with text, but with graphics, for example, that is, it involves mouse manipulation.
It is also advisable to place the mouse on a pull-out shelf next to the keyboard. If this is not possible, then in thoughtful modifications a special platform is formed for it.
Medium and includes a compartment for the system unit, open on both sides. It is located near one of the sidewalls, and in no case in the center under the operator’s feet. In compact models they often do without it, which is not an advantage: the system unit on the floor collects dust and quickly becomes dirty.
Usually it even includes side shelves at the bottom for placing peripherals - a router, printer, speakers, etc. If we are talking about a home workplace, the number increases markedly. Their sizes and layout depend on the nature of their professional activities.
A computer desk must have holes for cables, and often special fasteners that allow you to assemble the wires into more convenient bundles and secure them to the furniture.

The manufacturing materials for both categories of furniture are the same. Most often these are chipboard and MDF; in modern models, both can be used. Wood is used extremely rarely for computer desks - it is unprofitable, and glass, despite its extreme decorativeness, is suitable only for compact models. It is irrational to equip a large table with complex add-ons for all types of glass equipment.

Furniture dimensions

Like any other furniture, there are optimal, maximum and minimum allowable dimensions. But another difference between a computer desk and a desk desk is the dependence of the parameters not only on the position of the operator, but also on the size of the equipment used. And they can vary noticeably depending on the model.

The following video will tell you how to choose the right computer desk for your home:

Depth

The maximum is limited by common sense. Even if the screen is placed at a distance of 70 cm from the operator, a modern flat model does not require more than 60 cm in depth. 70 cm is a value with a reserve; there is no special need for it. It will not be possible to place anything behind the screen - the cables will not allow it, and the monitor heats up during operation. A wider tabletop simply will not be used, since all equipment that needs to be controlled should be at arm's length - 60 cm.
The minimum is due to the structure. The tabletop can be reduced to 50 cm, or even up to 40 cm, but in this case the monitor will have to be placed on a stand, otherwise it will be too low from the line of sight, and the operator will have to move back with the keyboard as far as possible to achieve the required distance between the eyes and screen.

Moving the display away from the center is not allowed. For an operator of any age, the need to turn toward the screen results in spinal curvature.

The optimal value is 60 cm, which allows you to move the monitor to any convenient position.

Length

The maximum is not limited at all. If the computer desk also acts as a writing desk, then its length can reach 2 m, because both the equipment and writing utensils must be kept in order. In addition, writing requires more space on the tabletop. There are double and even triple models - the latter, of course, are intended for an office where two or three workstations are arranged.
The minimum length of a stationary model is determined by the area of the workplace - this is 60 cm. Mobile and folding models can have a smaller length - 50 cm. The keyboard is located on a pull-out shelf, and the mouse has to be left on the table, which is not very convenient. With rare exceptions, there is no compartment for the system unit, and space for other equipment or materials cannot be found. This product is suitable for cases where the computer is used mainly for games.
The optimal width is calculated as follows: the operator’s workplace is at least 60 cm, and preferably 80 cm, the width of the compartment for the system unit is 20–25 cm, the width of the cabinet is at least 40 cm, otherwise it is useless. As a result, they get 120–145 cm. It is desirable that there are open niches above the compartment and cabinet - for a scanner and router, for example. The printer can be installed on the add-on shelf, just like the speakers.

The next video will tell you about 55 interesting models computer desks for home:

Height

The main table top, if there is one, has a standard height for writing - 75–78 cm. A shelf for the keyboard, which is more important for working on a PC, is placed at a distance of 50–75 cm from the direct line of sight. Both values depend on the user’s height and need to be corrected. There is no minimum or maximum in this case.
The height of the superstructures is not limited in principle. If the table is combined with a cabinet or rack, the latter can reach a height of 210 cm and include not only shelves, but also blind compartments and even wardrobes. For someone working on a PC, the most important area is the working one - at arm's length, which gives a height of 130–140 cm. The remaining shelves in any case will be occupied by materials and objects that are not constantly used.

The dimensions of the drawers and shelves are selected according to the size of the equipment used and the features of working with it.

Recommended for scanner pull-out shelf so that the cover of the device can be lifted freely.
A wide but not too high shelf is suitable for the printer.
The MFP will require a spacious cell open on both sides, the router will fit freely in a niche above the cabinet, and so on.

Types of products for the home

A fundamental issue when choosing a computer desk in a home is its purpose.

PC for games - if the machine is used only or mainly as such, the dimensions of the table for it may be minimal. Of the additional equipment, only speakers and a modem are needed here, and these devices are small in size. So a compact small table - preferably straight, with a monitor stand and speakers - is a perfectly acceptable choice. Important feature A good model of this kind is a mouse pad. If on the right or left side - for a right-handed or left-handed person, there is enough space on the tabletop to lean on your elbow, then the table can be considered successful. If not, then there must be room for the mouse on the sliding shelf under the keyboard, otherwise a long game will result in wrist joint syndrome. If this condition is not met, the model fails.
A table that combines the functions of a desk and a computer cannot be compact. A comfortable and correct position when writing requires a large area of the tabletop, for which you need to put the monitor and mouse away in an unknown location. If you ignore the rules and try to place all the accessories at a width of 50 cm, poor posture and stress on the joints are guaranteed. This model includes two workstations - for a PC and for writing, so its minimum length will be 160 cm and width - 70–80 cm. It is especially important to comply with these requirements if the table is intended for a schoolchild.
Workplace - takes into account not only the convenience of the operator, but also easy, free access to the periphery. The larger it is, the larger and more complex its design. Saving on space here is possible only due to a complex high superstructure, so such furniture must be selected taking into account the features of the interior.

By design, computer desks for the home can be divided into several groups.

Straight - placed along the wall or perpendicular to it, forming a working corner. Most often they have geometric shapes inherited from written ones, but modern versions increasingly include curved tabletops: opposite the operator, the width is smaller, since here it is determined only by the distance of the monitor, and closer to the edges it increases, which allows you to place volumetric periphery.
– triangular or L-shaped, designed for installation in a corner and use space more economically. This form is especially convenient for a combined computer and desk. In this case, one side of the L-shaped structure is made longer, and it is used for writing and reading, and the monitor is positioned exactly diagonally.

The angle forms psychologically closed space. In an adult, this causes overwork; in adolescents and young men, it provokes the formation of virtual addiction. To reduce the effect of isolation, such a model should be placed directly next to the window.

Transformers - are developed for cases when a computer desk is wanted to be hidden or combined with other pieces of furniture. So, in the first case, a blind cabinet helps to hide the PC. The monitor is placed on the shelf as on a stand, and serves as a tabletop hinged lid and doors of the lower cabinet compartment. In the second, a cabinet with open and blind sections is part of a computer desk.
There are also more original devices. For example, a chest of drawers, where a monitor and a shelf with a keyboard are fixed in the top drawer.
Models for laptops are stationary and folding tables of minimal size. Their special features are height-adjustable legs and the ability to change the tilt of the tabletop. This model is designed to work while sitting in a chair, on a chair, or even standing.

In addition, such furniture can be made in... They are especially popular.

How to buy inexpensively?

Choosing a computer desk is not an easy task. It's not about the cost of the product, but about other factors that are much more important. The model must ensure compliance with sanitary and technical standards, have a layout convenient for each type of activity, and only then correspond to the interior.

You can buy a computer desk ready-made:

in a furniture store, where such an item can be assessed not in a photo, but in reality: how comfortable it is to sit, whether the shelf is high enough for the keyboard, where the system unit is located, etc. It is advisable to come to the store with the dimensions of your monitor, printer, MFP, etc.;
On online platforms, where a variety of manufacturers are represented, there is undoubtedly more choice. However, here you can only evaluate the appearance of the model, but the convenience of the layout will have to be literally calculate words using the data given in the product description. And yet, most often you can buy a computer desk inexpensively in an online store;
Model descriptions on manufacturers' websites usually contain more information. Here you can take advantage of special and promotional offers - purchase in installments, for example, discounts on certain products, and so on. An example of such a place of sale can be considered stores;
You can always try, which will significantly save your money.

The computer desk can be made to order. How much cheaper or more expensive it will be compared to those offered in the store depends on its parameters and content - add-ons, shelves, drawers, etc. The complexity of the designs does not cause a too significant increase in price, but the table takes into account all the features of the future user and PC.

The layout and structure of the table is more important here than the cost. It's not so much cheap, but compact models that are becoming popular.

The following video will tell you how to properly care for your computer desk at home:

A computer desk is purchased after, or even together with, a PC. Do not be deceived: there is nothing to do either on a desk or on a desktop computer, especially if it is used for work. Its productivity by 2/3 depends on the convenience and availability of equipment.

Each person has his own height - some are tall, some are short. But computer desks in most cases have standard sizes and a height of 0.75 m.

The question is, where did this value come from? And everything comes from there - from statistical data. We calculated the average height and made it according to it, but what about people above or below average? Just choose the appropriate furniture for yourself, otherwise you shouldn’t expect anything good from the wrong dimensions. But in essence, if a person’s height varies within acceptable limits, then there will be nothing wrong with the fact that, for example, glass computer tables will be a couple of centimeters higher or lower than required. It's another matter when this discrepancy is significant.

What should be the height and dimensions of a computer desk?

There is a simple formula that can be used to calculate your ideal height. To do this: height is multiplied (cm) by the height of a standard table (cm) and divided by 175, and the result is the required value. For example, for a hero 190 cm tall, the table should be: 190*75/175=82 cm. Where can I get such a table?

For a short person, the problem can be solved by purchasing a height-adjustable office chair, but for a giant, this option is not suitable. In such serious cases, you need to order individually or purchase a finished product with an adjustable tabletop. It will be ideal solution, because such a table will suit all family members of different heights, but especially children. After all, they tend to grow. Why don't you buy a new one every year?

The only table that does not need to be adjusted to your height is a glass coffee table. In this case, the main thing will be the price factor and the general appearance.

Why is it important to choose the right sizes?

If the height of this piece of furniture is calculated incorrectly, then you can say goodbye to normal vision and a straight spine. An incorrectly selected computer desk can also cause rapid fatigue. A low table forces you to bend over and slouch, and working behind tall furniture involves constantly lifting your head, and it is not made of iron, just like your neck.

A modern person spends too much of his time at such a table, and he should not feel any discomfort. Only the correct selection of furniture can prevent a decrease in performance and avoid health problems. And there are several ways to solve this problem, therefore, choose suitable option you can always. And don’t think that good and high-quality things cost a lot of money and you can’t afford them. It is not difficult to find inexpensive glass tables, you just need to look for them in the right place.

Hello dear friends.

In order to answer this question, you need to first understand one thing.

Let's start with the minimum ones (since the maximum ones, apart from the height dimensions, have practically no restrictions).

So, if we consider an ordinary straight table, then its width consists of three (or rather four) dimensions:

Width of one pedestal
The width of the second cabinet (instead there may be a tray for the system unit, or it can be paired with it, or maybe just a stand or partition)
Place for the user
Gaps along the edges of the cabinets

If we consider this in numbers (of course, approximately), we get the following:

Minimum cabinet width – 400mm
The minimum width of the tray for the system unit is 240mm
The minimum opening between the cabinet and the tray (in other words, the opening in which the user should be) is 600mm
The size of the “overlap” on the cabinet and on the tray is 50mm
The average table height should be around 750 mm.

Total we get: 400+240+600+50+50=1340 (mm).

This is the minimum size of a regular straight table, which is located on two supports (a stand and a tray for the system unit).

Of course, if instead of a cabinet you design a side panel, move the tray inside the product, make it angular rather than straight, then you can achieve even smaller dimensions.

But in this case, the product will not be as convenient and functional as the first option we considered.

If we consider the same corner computer desk (meaning, located on two supports, although a third support is added for stability - a leg in the corner), then it will already have larger dimensions than a straight one.

Let us clarify once again that the product options under consideration are the minimum possible dimensions for each option.

Let's take the same parameters as for a straight table, that is:

The first support is one pedestal
The second support is a tray for the system unit
Opening for the user – 600mm
“Overlaps” – 50mm

But for angular options these values are not enough. One more quantity is needed - the width of the wing of its cover (and it, as can be seen in the figure, has two wings)

The optimal width (depth) is 600mm.

With these dimensions of the lid, we will make the depth of the boxes (supports) 500mm.

In this case, the dimensions of the corner product (the supports of which are the cabinet and, and the distance between them is 600 mm) will be 1264 mm by 1424 mm (in other words, these are the dimensions of the table top).

That's all.

See you in new posts.

When choosing a comfortable desk, it is necessary to take into account not only its design and materials, but also the height parameters. This characteristic is one of the most important, despite the fact that many consumers forget about it after finding a model they like. A desk of inappropriate height can lead to health problems, so you simply cannot ignore this characteristic of furniture.

Peculiarities

Users of all ages can spend time at desks most day. Such furniture can be used not only in home interiors, but also in offices. It is always convenient to work behind it, and, as a rule, high-quality writing structures fit on the tabletops a large number of different items.

However, choosing similar products, necessary Special attention pay attention to their height. And it doesn’t matter at all whether you buy a table for an adult or a child.

In both cases, the furniture must be made with high quality so that working on it does not lead to problems with the spine.

One of the main parameters of these interior items is their height. If you purchase a model that is too low or too high, it will be very uncomfortable to sit behind it, and your posture may also deteriorate greatly. Often, working at such tables leads to annoying pain in the neck and lower back. Sitting at a desk at the wrong height for long enough can even lead to noticeable headaches that interfere with your work.

This parameter is no less important if you are looking for a table for a child’s room. A growing body should not be placed in uncomfortable conditions, even while doing homework or reading books.

As a rule, incorrectly selected tables lead to curvature of the spine of young users, which is very difficult to deal with.

Standard sizes

Few people know, but today there is a special standard system called “modulator”, in accordance with which standard parameters absolutely all furniture produced today, including the height of desks. This parameter plays one of the most important roles, because it primarily affects the position of the user sitting behind it.

Being behind an excessively low structure, a person will slouch and lean his body forward, but if the user is working behind a too high product, he will have to constantly raise his head.

We should not forget that correct position means a perfectly straight back, calmly lying forearms and the absence of unnecessary stiffness in the shoulder area. You also need to remember that your legs should be on the floor and bent at an angle of 90 degrees.

Height in centimeters

As a rule, in the manufacture of modern desks, the main indicator is the average human height, which is 175 cm.

The creator of the useful “modulator” system, Le Corbusier, believed that the height of such furniture should vary in the range of 70-80 cm, therefore standard size most often it is 75 cm (in accordance with the average height of 175 cm, and for women - 162 cm).

Most users of standard build can rely on such parameters, however, in modern furniture stores you can also find non-standard options if the buyer has a more modest or, conversely, impressive stature.

In addition, the exact height of the structure can be found out and calculated using a special simple formula that looks like this: height x 75: 175. So, if a person’s height is 169 cm, then the height suitable furniture will be 72 cm.

If the user parameters are outside the standard limits, then You can choose a comfortable chair with height adjustment. However, in this case, we must not forget about the presence of a special footrest. It is necessary to ensure that the knees always remain bent at an angle of 90 degrees. However, it is also possible to order a table according to individual sizes. As a rule, such furniture is more expensive than standard display cases, but by purchasing it, you will receive the most convenient and suitable model for you.

Other options

If you want to choose a desk where work will be convenient and comfortable, then you need to take into account not only its height, but also its relationship with the width of the tabletop. This parameter means the distance from its left to right edge.

In the smallest designs, the tabletop takes up no more than 60 cm. Of course, such furniture will be a real “salvation” for a small room, but still experts recommend buying more spacious options.

The correctly calculated depth of the product for an adult user is 25-60 cm.

The area on which the legs should be placed should not be less than 52 cm. It is considered quite important to identify the width and height of the chair.

According to calculations Le Corbusier The most comfortable and optimal seat width is not exceeding 40 cm. As for the height, it should vary between 42-48 cm.

Adjustable model

Modern manufacturers produce not only standard stationary designs, but also more sophisticated designs that can be adjusted at your discretion at any convenient time. Often these models are purchased for children's rooms, since they can “grow” with the young user without harming his health.

The essence similar models tables lies in their ability to raise and lower the tabletop, thanks to special moving legs (usually there are 4 of them).

In addition, the good thing about adjustable options is that many of them come with a tilt feature.

Thanks to such useful qualities, such furniture can be used by several household members, since each person will be able to adjust the design to his own parameters.

Such specimens today are represented in a rich assortment and are in great demand. They are made from the most different materials, from cheap plastic to natural wood. There are also interesting options combined with a chair, the height of which can also be changed at your discretion. Otherwise, such models are called desks.

How to choose?

Before you go to the store to buy a table, you should decide what kind of sample you need: a written one or a computer one. After this, the issue regarding the cost of furniture should be resolved. The price of the table will depend on the following important parameters:

production of the product. Of course, options released under famous brands and big brands. However, such expenses are completely justified, since such products most often serve for a long time and do not lose their attractiveness even after many years;
material. The cost of a desk is also affected by the material from which it is made. The most inexpensive are models made of chipboard, MDF and plastic, and the most reliable and expensive are structures made of solid wood;
dimensions. As a rule, small desks are much cheaper than large options, since they require less raw materials during the production process;
decorative elements. Affects the price finished product and the presence of certain accessories in it. The higher its quality and more interesting design, the more expensive the table as a whole will cost.

How to choose for a child?

The choice of a desk for a children's room should be approached especially seriously and carefully, so that incorrectly selected furniture does not have a negative impact on the growing spine. If you want to purchase a truly high-quality and safe model, then try to follow some simple recommendations:

the recommended width of the tabletop in a design for a child should be at least 100 cm;
as for the depth, it should vary from 60 to 80 cm;
the young user should have a space of about 50x54 cm for his feet;
It is recommended to purchase designs with a small footrest located directly under the tabletop. If it is not provided by the manufacturer, then it should be purchased separately from the table;

The difference between the height of a chair and a desk also plays an important role in choosing a design for a child. This parameter should be 20-24 cm;
When going to the store to buy such furniture, experts recommend taking your child with you so that he can sit at the table for a while before purchasing. At this moment, you need to check his position: the elbows and legs should be relaxed and not tense. As for the gap between the top of the table and the user’s knees, it should be 10-15 cm;
It is also necessary to take into account the distance of the upper part from the user’s eyes. It should correspond to the space between the elbow and the tips of the fingers;
psychologists advise taking into account the child’s taste preferences and desires. At the same time, you need to make sure that the tabletop of the product is spacious enough and not too cramped, otherwise working with such a model will not be very convenient;

The health of a person working at a computer is influenced by many factors, one of which is the height of the table. Incorrectly calculated height of the product can cause spinal diseases, as well as visual impairment. In addition, a person who feels discomfort when working at a computer desk spends much more energy and, therefore, quickly gets tired. In general, it is a hassle to have a table that is not the right height. Therefore, I propose to look into this issue in detail.

How should a person sit at a table?

Why does table height affect human health? Why not or? The fact is that it is the height of the table that can change the position of the person sitting at it. A table that is too low will cause the user to slouch and lean forward, while a table that is too high will cause the user to lift their head up and feel discomfort.

The optimal position for a person sitting at a “proper” computer desk is a straight back, forearms resting freely on the tabletop, without raising the shoulder girdle. As a rule, the countertop is at the level of the solar plexus. By the way, it should be noted that when sitting on a chair, your legs should be on the floor and bent at an angle of 90 degrees.

But how to achieve such a position? Are there any standards or formulas? To be honest, I also have my own opinion on this matter, which will be outlined below. But first, I bring to your attention the official standards for calculating table height.

How to calculate the height of a computer desk

So, we must immediately say that:

There is a standard height of a computer desk, which is 750 mm.

Where did it come from, and how was it calculated? Everything is very simple! The fact is that, according to statistics, the average height of a man in our country is 175 cm, a woman - 162 cm. It is for this height that the standard table height is calculated - 75 cm (750 mm).

If your height is shorter or taller, then you can individually calculate the height of your computer desk using the following formula:

Your height * 75 cm / 175 cm = table height

For example, your height is 182 cm, then the optimal height of a computer desk will be calculated as follows:

182 cm * 75 cm / 175 cm = 78 cm

However, often in a house there is not just one person working at a computer desk, but several family members. And most often, these are people of different heights. If you make yourself a table to suit your height of 192 cm, how will your father-in-law, who is 160 cm tall, or your mother-in-law, 155 cm, feel at it?

Come on, father-in-law! You can always come to an agreement with your father-in-law. But mother-in-law... How to convince “mom” that jumping up while working at the computer and hovering in flight while tapping on the keyboard is comfortable? I hope you all understand that this is simply unrealistic. Therefore, here is my personal point of view regarding calculating the height of a computer desk.

If possible, choose a standard height

From the title you probably guessed that I recommend, if possible, choosing the standard table height – 750 mm. By the way, on our website all models have a height of exactly 750 mm. Now I will explain why.

Look, if your height is 182 cm, then the calculated table height should be: 78 cm. We have a difference of 3 cm from the standard table height. In principle, in my opinion, an error of up to 3 cm is quite acceptable. Therefore, the permissible range of user height is from 168 cm to 182 cm. That is, for people whose height is within this range, a computer desk with a standard height of 750 mm is quite suitable. And it is this height that office furniture manufacturers make tables - since it is universal for the majority of residents of our country.

Options for solutions to non-standard situations

But what about those who are 155 cm or 195 cm tall? After all, there are quite a lot of such people. Do they have to suffer all their lives, sitting at uncomfortable tables? Of course not. Here I personally see three options for solving the problem:

1. You can achieve a comfortable position by changing the height of the chair. Modern office chairs allow you to adjust the height of the user's position relative to the table. So why not take advantage of this? But this option is suitable for people whose height is below 168 cm. You can simply adjust the height of the chair, setting for yourself the most comfortable position in height relative to top cover table.
However, I want to note that if you raise the chair higher, your legs will no longer be bent at the knees at 90 degrees. Therefore, you definitely need to install a low stand under your feet. This way you can ensure a comfortable position at a standard height computer desk. But this method, I repeat once again, is suitable for short people. But what about tall PC users? And for tall people, perhaps the second or third option is suitable. Let's move on to them.
2. Make a table of the proper height to order. This method is a good solution for tall people, and it is also suitable for those whose height is below 168 cm. You have the calculation formula. So, I think you can quickly determine the height of your computer desk by making it yourself or custom-made. And finally, the third way.
3. Make a table with an adjustable tabletop height. Height-adjustable tables are now popular among manufacturers of furniture for schoolchildren. The child grows, and his desk “grows” with him - this is the correct and thoughtful approach. Actually, we can take it into account when designing a computer desk, at which a short mother-in-law, 155 cm tall, and her beloved son-in-law, 192 cm tall, will work. We can make it possible to adjust the height of the tabletop to suit the height of each user.
I would not call this method ideal - it has a number of disadvantages. For example, the ability to design some models of extensions for such tables becomes more difficult. Also, to change the height of the tabletop, you will have to remove everything from the table. However, it is possible that this particular option may be the most suitable for someone. a good decision question.

So, we looked at the issue of calculating the height of a computer desk. I hope I was able to present the information in an intelligible and understandable manner. All that remains is to make a decision in favor of one option or another. But you must do this yourself. I wish everyone good luck! I'm sure you will succeed!
