Perhaps there is no area of human life left that has not yet felt the influence of modern high technologies. Today, the computer goes hand in hand with a person, in his professional and even personal life. In the process of school and university studies, at work and when planning vacations, we turn to it, trying to facilitate and optimize our work and time.
Considering the role of computer technologies in medicine, we can confidently speak about their contribution to real improvement in the quality and length of life.

The health of a person working at a computer is influenced by many factors, one of which is the height of the table.
The chest protrudes forward, and the shoulders, on the contrary, are slightly lowered and set back.
Features of a computer desk
A computer desk is not ordinary desk furniture. And this is its main feature.
One of the most important requirements for the design of a computer desk, compliance with which ensures healthy and fruitful work.
It has distinctive features from a writing desk:
- Required space for keyboard
- Space for the system unit
- Space for additional items
- Convenience when working at a computer
You can achieve a comfortable position by changing the height of the chair.
In addition to these points, computer furniture can have a separate area:
- For printer
- For disks
- For books
- For working with writing instruments – notebooks, textbooks
When choosing a computer table, this must be taken into account. And all these nuances affect primarily the size of the product and the choice of location for it.
Important! The computer desk must be very stable and not wobble, since the operation of the system unit or laptop depends on this. A product that is subject to vibration may damage your computer.
Consequences of the wrong choice
The first item on the list of criteria is convenience. If the table does not meet this requirement, then full-time work at it is out of the question. Incorrect posture primarily interferes with normal blood circulation. Result: congestion, swelling, pain. And for a child whose body changes every minute, an incorrect position at a desk contributes to an increased risk of abnormal development of the muscular corset.

Computer desk dimensions
Once the basic and additional functions of the furniture have been selected, it is important to determine its size. It is worth considering that they depend on the location in which this product will be installed.
The table can be custom made to the appropriate height.
The size of computer furniture also depends on the place where it should be placed. If you plan to place it against a wall, then it is better to choose narrow rectangular models. And if you plan to place it in a corner, then wide corner options are suitable.
Advice. It is worth paying attention to the tabletop, cut in a semicircular shape. It increases the working area and is injury-proof for households.
With correct posture, a person can easily and naturally stand, walk or sit.
For a computer table, it is also important that the keyboard shelf be retractable. This will allow you to relax your hands when working at the computer, and will also save work space on the countertop.
Other important details:
- The presence of wheels will allow you to move the product in the future as needed.
- Slots for wires. They will make the interior more homely and cozy.
- Leg room. It will be observed if the model has a depth of at least 50-60 cm.
Are other parameters important?
Correctly selected height will not make working at a narrow desk comfortable. Conversely, a wide canvas at the wrong height can turn out to be quite comfortable. Therefore, when choosing, it is important to pay attention to the following parameters:
- tabletop width is at least 60 cm for a child and 80 for adults (more is better);
- depth - from 35 cm for a child, from 50 for an adult (the principle is the same);
- legroom - to the depth of the tabletop and at least 50 cm in width.
In relation to various types of furniture it looks like this:
- for the kitchen table, the criteria for depth and width are taken;
- for written and computer - all three parameters;
- for lunch, the first pair of values is doubled, resulting in the required minimum.
Standard computer desk height
The most important point when choosing a computer table is its height. It is the most difficult, since on one side the table has a fixed height, and on the other, it is designed for different family members with different heights. The standard height of a computer desk is 75 cm according to all-Russian GOST. This standard should be taken into account if a table is purchased for several family members. In this case, it will be optimal for everyone.
Incorrectly calculated height of the product can cause spinal diseases.
But if the product is intended to be used by several household members of the same height or by just one person, then its height should be calculated using the formula: Person’s height in cm * 75 / 175 = table height.
It is the height of the table that can change the position of the person sitting at it.
Other parameters should be taken into account:
- The screen must be at least 50 cm away from the body
- The top line of the monitor should be at eye level
- Elbows should be at an angle of 80 degrees when working on the keyboard.
- When landing, your back should be straight and not deviate more than 15 degrees.
- Legs must have firm support
What's good about an adjustable desk?
The main advantage of such furniture is the ability to adapt to current needs, eliminating the need to purchase several different-sized models. Adjustable options are compact, which is especially useful in city apartments. The only negative is that they are not designed for heavy loads. Their limit is 45–50 kg.
REFERENCE! The table can be equipped with mechanical or electronic transformation mechanisms. Often the manufacturer provides not only a change in height level, but also an increase in area.
Is it possible to change the standard
If there are several computer users in a family, then there is a high probability that their height will differ. In this case, choosing a single universal computer table will be very difficult.
But you can use the following tricks:
- Use an adjustable tabletop height. This is the most difficult option, since it involves changes inside the table itself. To do this, you will have to remove and reinstall the monitor.
- Monitor stand with adjustable height. This is a more convenient method that allows you to tilt the monitor according to the user's height. The only caveat here is that when you adjust the height of the monitor, the height of the keyboard does not change. This may be uncomfortable on the user's hands.
- Adjustable table support. It allows you to change the height of the entire structure quite smoothly. Thanks to this, there is no need to rearrange objects.
The optimal position for a person sitting at a “proper” computer desk is a straight back.
Please note that changing the height of the monitor and keyboard must be harmoniously combined with changing the height of the seat. Otherwise, working at the computer will be inconvenient.
Varieties

Advantages of school models:
- suitable size;
- drawers for storing office supplies;
- wide tabletop;

A desk with shelves is a practical solution for a schoolchild
Dependence of table comfort on height
Convenience, which means the time that the user can spend at the computer without fatigue, depends directly on the height:
- Computer desk
- Monitor heights
- Keyboard heights
- Tilt of a person's back
- Leg angle
- Leg supports
There is a standard height for a computer desk, which is 750 mm.
If a person's gaze is too low, the neck muscles will become overstrained. This will lead to overload of the cervical vertebrae and fatigue of the shoulder muscles. If the keyboard is placed too high, it will lead to wrist fatigue. Your fingers will become numb over time. This will lead to pain in the wrists and joints of the hands.
Modern office chairs allow you to adjust the height of the user's position relative to the table.
If the keyboard is positioned too low, the person’s torso will also tilt and the head will rise. This will lead to overwork of the cervical vertebrae and even to a neck hernia. In this case, the lower back and back will be overstrained, which will lead to fatigue and pain.
As a result of incorrect leg position, the hip joints and lymph nodes will be overstrained. This can lead to improper blood circulation in the lower extremities. As a result - swelling of the legs. The hardest part will be on the feet and ankle joints. This will be felt especially strongly in hot weather, which complicates the circulation of fluid in the body.
Many people are comfortable working while standing.
Stagnation of fluid in the pelvic area leads to inflammatory diseases of the organs in this area, which has a detrimental effect on women's and men's health. In addition, overload of the spine in any case affects the overall fatigue of the body.
Height-adjustable tables are now popular among manufacturers of furniture for schoolchildren.
The optimal height of a computer desk, on the contrary, increases human performance and student performance. It also gives a boost of energy and increases productivity.
Standard sizes depending on the type of model
The ability to adjust the tables allows you to quickly adjust the size to the individual physiological parameters of a person. In addition, given the need to save space in city apartments, adjustable models become multifunctional: if necessary, an adjustable table can be converted from a desk to a dining or kitchen table.
Currently, models are produced equipped with an electronic adjustment mechanism. There are options in which it is possible to increase the surface area due to retractable elements.
The only drawback of such models is their low strength. They are usually designed for a load of 40 to 50 kg.
Straight
Straight tables are the most common design that is appropriate in any interior. The most important indicator is height, which is calculated based on a person’s height. With the most common height of men (175 cm) and women (162 cm), the standard height will be 75 cm. Thus, the dimensions of structures for adults can be as follows:
- height (distance from floor to tabletop) - 70–80 centimeters;
- length - not less than 60 cm, but not more than 120 cm;
- depth (distance from the front to the back wall) - 35–80 cm (you need to focus on the length of your legs).
Such standards are used by the overwhelming majority of manufacturers of tables for adults. Completely different requirements for models intended for children. The table height here is smaller, the minimum is 52 cm.
The width (depth) should be chosen taking into account the specific use. For the option on which they will exclusively write and do homework, 60 cm will be enough. If office equipment is used, you can increase the width to 80–90 cm so that all the necessary equipment can be placed on the tabletop and your hands can be placed as comfortably as possible.
For greater functionality of the design, it is also supplemented with elements where you can store books, notebooks, and office supplies - usually these are roll-out drawers or closed shelves. The height of the latter for a child will be comfortable at 210 cm. The recommended distance between the shelves is no more than 40 cm, and their depth is desirable no more than 30 cm.
Angular
Corner writing structures will help fill empty spaces and create a corner of comfort in which a person will work. The parameters of adult models are specified in the quality requirements approved by law, and many product manufacturers follow them:
- height - 52–80 cm;
- the length of one of the sides is from 150 to 170 cm;
- the length of the other plane is 120 cm;
- depth - from 50 to 95 cm.
For a children's corner table, only the height changes, the initial value of which is 52 cm. Taking into account the individual characteristics of the user, it is possible to make the most comfortable option for a schoolchild to order, but this will increase the cost of the furniture.
Often the design located in the corner is also computer-generated. It provides space for accessories (printed keyboard, working display, main system unit). Such zones are manufactured with the following dimensions:
- a roll-out shelf for placing a printed keyboard - 10–15 cm wide, which will allow you to conveniently position the accessory;
- small shelf for the screen - no more than 12 cm;
- stand for the system unit - 10-15 cm above the floor, which will not allow the equipment to overheat.
For children, a desk that “grows” with the baby is an excellent choice. It will help maintain normal posture, save parents money, because they will not have to periodically purchase new designs. Parameters are changed using sliding mechanical or electronic systems.
The optimal sizes of sliding tables are:
- height - from 46 to 82 cm;
- length - varies between 70 and 120 cm;
- depth - from 50 to 95 cm.
How to choose the right table
Selecting a computer desk is based primarily on the requests of family members. In this case, you should consider how they will use additional equipment:
- Smartphones
- Printer
- Set-top boxes
- Laptop
- Video cameras
- Scanners
Also, do not forget that schoolchildren can also use notebooks, books, and drawings. The width of the computer desk also depends on the location of all these items.
The standard width of such a product should be at least 60 cm. However, it can be larger, as it requires combination with a desk. In addition, the wider the product, the less clutter there will be. Since with a convenient width and length, it will be possible to place the necessary items of all family members here.
Desk for a schoolchild: a creative approach to organizing the workplace
Studying can become much more interesting if the child is surrounded by interesting objects and creative furniture. You can come up with anything - depending on how much your imagination is enough.
Decorate the area around the table with your child. Self-drawn pictures, interesting photographs, original watches are great ideas for this purpose.
The part of the wall to which the desk adjoins can be decorated in an unusual and useful way by installing a fiberboard panel or a chalk board here. Now it’s easy to fantasize about the design of your work area, supplementing it with calendars, notes, motivational quotes, drawings and other little things.
Place clear glass on the table that matches the size of the tabletop. Under it, the things the child needs will always be in order and in sight - drawings, study materials, a calendar, notes, etc. In addition, this is excellent protection against possible damage.
More examples of school desk design are presented in the following photos.
