What should be the height of the computer desk?
Perhaps there is no such sphere of human life that has not yet felt the influence of modern high technologies. Today, the computer goes hand in hand with man, in his professional and even personal life. In the process of school and university studies, at work and when planning holidays, we turn to it, trying to facilitate and optimize our work and time.
Considering the role of computer technologies in medicine, we can confidently talk about their contribution to a real improvement in the quality and life expectancy.

The health of a person working at a computer is affected 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.
It is hard to imagine that a modern average dwelling or office space can do without a comfortable and properly equipped place to work at a computer.
An incorrectly calculated height of the product can cause diseases of the spine, as well as visual impairment.
At the same time, in the process of choosing a place for a table, engineers advise adhering to the following basic rules.
- Provide for easy access to the electrical network in advance. It is desirable to completely exclude electrical transfers and all kinds of extension cords. Sockets, if possible, equip with grounding.
- Try to provide the working surface of the table with natural sunlight, which would fall from the left side.
- In the cold season, do not place heaters close to the table. Thus, the temperature conditions of the equipment operation are not violated.
- The floor surface on which the computer desk will be placed must be correct in level, with no irregularities and relief.
In general, it is troublesome to have a table of improper height. Therefore, I propose to look into this issue in detail.
Standard, the height from the floor to the countertop is 75 cm.
It will be convenient and pleasant to work and study at a table set according to these rules. However, the requirements observed in relation to technique will not cost anything if, sitting at the table, one does not follow certain rules of healthy posture.
In addition, a person who feels discomfort when working at a computer desk consumes much more energy, and, therefore, quickly gets tired.
Correct posture at the computer desk
The concept of posture refers to one or another independent position of the human body in space. She is right and wrong.
Why does table height affect human health?
But humanity still believes that the intelligent use of a computer can bring undeniable good.
With proper posture, a person can easily and naturally stand, walk or sit. There is no active tension, the body and head are held straight. The chest protrudes forward, and the shoulders, on the contrary, are slightly lowered and set back. Tightened, not prominent belly.
A table that is too low will make the user slouch and lean forward, and a table that is too high will cause the user to lift their head up and feel uncomfortable.
Opposite characteristics: stoop and lowered head and shoulders, walking on half-bent legs, etc. give out the owners of the wrong, unhealthy posture. And it negatively affects, among other things, the work of internal organs.
The optimal position of a person sitting at the “correct” computer desk is a flat back, forearms lie freely on the table top, without lifting the shoulder girdle.
However, not only heredity determines the ability to hold the body correctly, but also objective external factors. Posture begins to form already in early childhood, and this is precisely the period that allows active intervention for the sake of further correct development.
As a rule, the countertop is at the level of the solar plexus.
The vast majority of models of computer tables are universal and can be used as desks. So, let's imagine that the keyboard shelf is pushed back, and we sit down at the tabletop to just write in a notebook or study a book. How to position correctly?
- Between the chest and the edge of the table, a distance approximately equal to the palm of your hand is observed.
- Both when writing, and especially when reading, do not allow the chest to rest on the edge of the table top.
- The standard height of a computer desk is designed to provide an optimal distance (30-35 cm) for vision and posture from the eyes to the surface of the table top.
- It is best to write with the elbow lowered 5 cm below the edge of the table.
- The legs of the entire foot are on the floor, while the thigh and lower leg should form a straight or slightly obtuse (100 - 105 °) angle between them.
By the way, it should be noted that while sitting on a chair, the legs should be on the floor and be bent at an angle of 90 degrees.
How to keep your posture while working at the keyboard?
- The height of the chair should provide a right angle between the thigh and lower leg; the seat should not be too soft.
- The surface area of the chair is occupied by at least 2/3.
- Let the back of your chair be the measure of your back. When working, try to snuggle up to her.
- Ideally, the shoulder blades are drawn together, the abdominal muscles are relaxed, one shoulder is not higher or lower than the other.
- Don't cross your legs. With the duration of this position of the legs, the blood supply is significantly disturbed.
- Achieve from your posture the distribution of weight only on the hips; computer monitor, may be at eye level or slightly higher.
But how to achieve such a position?
The feeling of comfort from being in such a correct position does not come immediately, but a little effort and perseverance, in the end, will do their good deed.
Look, if your height is 182 cm, then the calculated height of the table should be: 78 cm.
The main types of structures, and the main parameters of computer tables
- Classic, straight.
When the user is positioned perpendicular to the length of the table and, accordingly, to the monitor. Such models are conveniently placed along the wall or room partitions.
- Angular.
The design of the table is conveniently built into the corner of the room. In this case, the user sits either in the diagonal of the table and perpendicular to the monitor, or facing the main length of the table and in a half turn to the screen.
Therefore, the user's allowable height range is between 168 cm and 182 cm.
The choice of a specific design, of course, depends on the spaciousness of the room and the furniture "neighborhood". But the main parameters and dimensions of computer tables - depth, length, and height should be guided by the tasks that a particular user sets for himself, and also take into account his physiology.
And it is precisely this height that manufacturers of office furniture make tables - since it is universal for most residents of our country.
Computer desk dimensions
One of the most important requirements for the design of a computer desk, the observance of which ensures healthy and fruitful work, is its correct height. Standard, the height from the floor to the countertop is 75 cm.
You can achieve a comfortable position by changing the height of the chair.
But still, the growth of most people does not correspond to what is considered to be the "golden mean". And even for such a non-standard situation, there is an excellent and simple calculation formula: the product of height by 75/175 cm.
Make a table of the proper height for an individual order.
There is no active tension, the body and head are held straight.
For example, if the user is 183 cm tall, the calculation of the optimal table height will be as follows: 183*75/175 = 78.43 cm.
Make a table with adjustable tabletop height.
With proper posture, a person can easily and naturally stand, walk or sit.
Internet addiction and the substitution of real life for virtual life are well-known problems of Hi-tech technologies. But humanity still believes that the intelligent use of a computer can bring undeniable good.
The child grows, and with him his desktop “grows” - this is the right and thoughtful approach.
Actually, we can take it into service by designing a computer desk at which a short mother-in-law with a height of 155 cm and her beloved son-in-law with a height of 192 cm will work.
The concept of posture refers to one or another independent position of the human body in space.
