The height of a standard work table. What should be the height of the computer desk

16.06.2019

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

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

Peculiarities

Nowadays, a computer desk is indispensable. These pieces of furniture are special in that they can be used in a variety of settings. It could be like city apartment or private house, as well as 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 both in adult and children's bedrooms, because today even the youngest users effortlessly master the corresponding technique. A well-chosen computer desk is perfect for both work and play and relaxation. These interior items are multifunctional, as they can be used not only for working on a laptop or desktop PC.

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

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

It should be as convenient as possible to work and study at such a table, so modern furniture factories produce many options that have a very different structure, as well as various lengths, heights and widths.

These parameters play one of the most important roles in choosing the right model of a computer desk.

The fact is that, working on a design of inappropriate sizes, the user will be very uncomfortable and uncomfortable. Moreover, the constant operation of such tables can cause significant harm to human health. So, working on a model that is too low, you will have to constantly bend over and move the body forward, which over time can lead to a serious curvature of the spine and stoop, not to mention aching painful sensations, which can become your constant companions.

No less seriously you need to approach the dimensions of the computer desk that you plan to buy for a child. Here it is very important to pay attention not only to the width and length of the countertop, 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 one size or another 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 a small tabletop.

If you are looking for a more roomy 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 refer 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 perform the following actions: height (in centimeters) x 75 cm (standard height of PC tables) / 175 cm = structure height

The width of the computer desk should not be unnecessarily miniature. It is recommended to add another 30-40 cm to the specific parameter of a particular tabletop. Thus, you will provide extra space for bedside tables;
The minimum correct depth of a computer model without add-ons is 45 cm. Of course, if there are other additional components in the design, then this indicator can be more, 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 the height, the rest of the 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. The choice of the correct option mainly depends on the position in which the person will sit behind it.

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

back - straight;
forearms - in a relaxed state;
shoulders - not raised and not tense;
muscles are also relaxed;
legs should be even and be on a special stand, a shelf under the table top or just on the floor.

The classic table height for computer equipment is 750 mm (75 cm). It is calculated based on the average growth of both sexes. So, the average height of men is 175 cm, and women - 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:

chairs with adjustable height;
ordering a design according to individual sizes;
worktop with adjustable function.

However, the design width indicators depend on several important factors:

the minimum is an indicator of 60-70 cm, and the maximum is 80-95 cm;
department for system block should take at least 20-30 cm;
first take a free place to place the cabinet and add another 30-40, 45 cm to the whole structure;
products of an angular structure should have a turning space of the tabletop, which is 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 detail, 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 in which there are additional superstructures have a depth of 60-70 cm;
corner specimens equipped with shelves most often have a depth exceeding the mark of 85 or 90 cm.

Non-standard solutions

Many consumers are faced with the fact that none of the computer desk models from standard range. In such cases, do not panic and get upset. Fortunately, today many manufacturers offer a custom-made furniture service. So, you can come with your sketch and measurements in order to order the perfect design of optimal dimensions. Of course, such products most 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 a person with any height and configuration, but also because they can be selected even for a compact home and save free space.

Table supports, table tops and monitor stands are adjustable. If you combine such furniture with comfortable adjustable chairs, as a result you will get a universal tandem for which all family members can work, each time adjusting the functional structures for themselves.

functional models

Modern manufacturers produce a great variety of computer tables with different structures and functional components of the configuration. Let us consider in more detail the most popular and sought-after options that are found today in many dwellings:

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

Corner. These models are the second most popular. Their main advantage is that they allow you to save space in the room, as they can be placed in a free corner. In addition, in them, as a rule, the system unit can be moved a little further, thereby not cluttering up working space. All items on the corner tabletop are always 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 fork out for such designs. At these tables, the user can be diagonal, and his face is directed to the corner. Often, miniature mini-tables have a similar structure. Their disadvantage is considered insufficient functionality. Bedside tables, as a rule, are present under the main cover of these models, and sliding 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 extremely rarely equipped with superstructures. Much more often in them you can find small bedside tables with drawers.

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

Rack. Today, well-thought-out computer desk designs are very popular, in which there is an additional rack. Most often, such options have considerable dimensions, but they should not frighten and 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 rack combined with a computer desk.

Examples in the interior

Today, each consumer has the opportunity to choose the perfect computer desk that will organically fit into his home. At the same time, it does not matter at all what style the furnishings are made in. It can be both an eternal classic and a shocking avant-garde.

Corner designs of computer tables are very popular today. They often combine several different colors. 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 put such a table in a rough light gray loft-style room with a milky gray parquet floor, laconic wall paintings and a dark round carpet on the floor.

The size and height of the computer desk play an important role in the efficiency of work. Working at an ordinary or desk is already quite inconvenient due to the many components of a computer such as keyboards, various cords and connectors. Particular attention should be paid to this issue if there are schoolchildren in the house. So that the child does not have health problems, it is advisable to purchase a special table that will simultaneously replace a regular or written one. The place for study should also be attractive, comfortable and cause a desire to do homework, consolidating the knowledge gained.

If at school it is impossible to control this process, since the desks have a standard, then at home it is within the power of any loving parent. Due to the fact that during sitting it strains a large number of muscles, the height of the table affects the degree of fatigue of the body. In other words, overexertion will affect the well-being of the child. Incorrect posture forms scoliosis. Currently, the choice is large enough, and in order to purchase a quality item, you need to have some knowledge.

First you need to decide on the location. It is advisable to place such a table by the window so that left hand was closer to him. Right hand will give a shadow, which further strains the eyesight. At the same time, size is important - the larger the better, but it all depends on the place where it will stand.

Now the production of furniture is so diverse that it is not easy to make a choice.

There are tables made of wood.
Also available with metal legs.
It is possible to order corner tables in accordance with the ordered dimensions.
With side drawers on one side or on both sides.
Attached to the table with shelves at the top.

We learned how to produce tables-transformers for growth, in which there are special mechanism, adjusting the height of the table from 53 to 80 centimeters for height from 109 to 200 centimeters, as well as the tilt of the tabletop under different types classes. They come with chairs with the same special regulator. Experts have calculated that, for example, for an adult with a height of 165-175 cm, during handwriting, the standard height is from 70 to 75 cm. For working with a mouse, from 68 to 73 cm, therefore, a retractable under the tabletop panel-stand for the keyboard.

Doctors recommend that when working at a table, a person’s legs should be stable on the floor, and even more so for a child. If the height of the table is large, then you need to substitute something under them so that they do not hang, but have a stable support. The best thing do wooden stand, which can be upholstered with fur. Today, new technologies have solved the problem of replacing and buying a new table in accordance with the age and height of a baby, schoolchild or student due to adjustment. The following table shows the height of the child and the ideal height of the computer desk and chair according to the approved GOSTs, which are indicated in the Appendix SanPiN 2.2.2 / 2.4.1340-03 "Hygienic requirements for personal electronic computers and organization of work."

Height in centimeters	Table height in centimeters	Chair height, cm
up to 80	34	17
80-90	38	20
90-100	43	24
100-115	48	28
115-119	50	29
119-130	52	30
130-145	52-58	30-34
145-160	58-64	34-38
160-175	64-70	38-42
above 175	75	46

You also need to consider how the wires will be placed and how far the sockets are located from the location of the computer desk. If this is not taken into account, then if the distance is too far, an additional extension cord and cords will be needed, and this will create inconvenience when cleaning the room.

When choosing, pay attention to the placement of the legs. There must be enough space. It can be in the middle if there are additional boxes on both sides. Since this is a special table, it is advisable to buy an appropriate chair, which has a height adjustment. When close to the table, its armrests should not rest against the tabletop due to the fact that this interferes with a smooth and comfortable seat. Adjustment is needed so that the hands do not overstrain from the discrepancy between the height and height of the table.

When choosing this type of furniture, the following criteria must be met:

the chair is comfortable and keeps the back straight;
the height of the table corresponds to the height, otherwise the legs rest on a special stand;
the table lamp does not blind and does not heat up; it is better if it is with a device that adjusts the height.

The most important thing when working is the correct posture. AT childhood the spine is not yet strong and therefore from time to time check whether your child is sitting correctly, determining by such external signs:

legs with full feet rest on the floor;
knees bent at right angles do not rest against the bedside table;
the distance from the knees to the tabletop corresponds to the size of the fist of the hand;
arms are relaxed, and shoulders are lowered and not tense;
the pits under the knees do not touch the edge of the seat;
the back is straight, not hunched.

Please note that the distance from the eyes to the monitor should not be closer than arm's length. The topmost line of text on the screen is slightly below eye level, not above. Since the computer is very dry eye sockets, take a break for 10 minutes every hour. Remember, the miser pays twice. Do not save on health and immediately buy a transforming table that will last more than one year.

For the convenience of working at the table, its height must be taken into account. This parameter affects the comfort of using furniture. standard height The table should be suitable for the average indicators of adults and children. Moreover, for each type of furniture, this parameter is different.

Purpose

In furniture, its parameters are the main ones. 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 during the period of work needs to lean forward, stoop. This causes curvature of the spine, as well as the appearance discomfort in 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 table for the kitchen is determined by the parameters of the person. The greater the growth, the higher the work surface should be. In this case, the furniture will be comfortable. For determining optimal height kitchen table rules are used:

With growth up to 150 cm, the design should have parameters in the range of 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 firms when creating furniture products. In this case, the parameter can be 87-90 cm. This is the standard table height, as it will be convenient for men and women.
If the growth is higher than standard parameters, then the furniture is created to order. At 185-200 cm from the floor to the countertop there will be 1 meter.

It is important that the furniture is comfortable for the whole family. Since it is impossible to select a design for each parameter, therefore, the average is calculated. For example, if the height of the wife is 150 cm, and the husband 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 the desks for children and adults is different. This should be taken into account when buying a design. If height-adjustable tables are created for children, then for adults everything is different. It is important to take into account the physique, size, height. Furniture should be selected based on these parameters.

In addition to height, length and width are taken into account. They must meet the standards. When these indicators are less, then there are inconveniences that negatively affect the state of the 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 the people of the earth is about 175-183 cm, the standard height of the writing table is 700-800 mm.
For 150-160 cm, it is better to choose 60 cm.
With a height of 190-200 cm, you need to order a height desk 85-90 cm.

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

Computer

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

There are rules to consider when choosing computer furniture:

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

If these rules are followed, it will be possible to prevent problems with the spine. A person will not have a curvature, deformation, which usually leads to serious illnesses. The height of the computer desk is set according to height. Usually it is 75 cm, which is designed for a height of 170-172 cm. The rest of such a product will be uncomfortable. Then you need to order the design.

Dining

Height dining table should be comfortable for everyone so that there is no discomfort during eating. When sitting behind such furniture, the relaxation of the body should be felt, 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 furniture height is 72-78 cm. To calculate suitable option the formula is used: furniture height \u003d 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

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

Height is required to determine height. If the product is selected for a first grader and a teenager, then the following parameters should be considered:

With growth 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 for a growing organism, 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 a right angle should be obtained with the lower leg and thigh.
The required degree of depth of the chair is set as follows - the seat of the chair should not dig into the popliteal joints.
Between the knees and the tabletop should be 10-15 cm or more.
The distance from the eyes to the surface of the structure should be the area from the fingertips 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 the width, shape, design of structures. Importance has the material, the presence of original parts. In sets with tables, chairs are often sold at a height suitable for comfortable use. The main thing is to use them for their intended purpose.

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

Solution of non-standard situations

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

You can adjust the size of the chair. There are many chairs sold in shops and markets that can change in height. So it will be comfortable to sit at the table. But then there may be inconvenience with the placement of the legs. And this negatively affects health.
Production of furniture to order. In this situation, it is preferable to focus on the growth of an individual in the family. You can define an average. A difference of a few centimeters will not be visible. But you can get the desired result only with a small difference in growth. Before manufacturing, a drawing is necessarily created.
You can choose a table adjustable table 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 there will be a custom design or on your own. The advantage of the method is the saving of the budget, in addition, it becomes possible to create a comfortable product.

Adjustable height

In addition to classic products, there are tables that are adjustable in height. These are mechanical modules or transformers. Often they have X-shaped supports, with which you can install given parameter. But there may be a retractable or electronic mechanism.

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

Comfort for the whole family - you can adapt to children and adults.
Compact and space-saving due to versatility.
Practicality and the ability to place in any place in the room.

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

Consequences of the wrong choice

Incorrectly selected furniture height creates tension, discomfort, fatigue. This applies to tables different cases. In the kitchen, this design also causes a lot of inconvenience. During the cutting of products, about 40 muscles work. If a workplace higher, the load increases markedly, and if lower, this causes rapid fatigue.

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

The desk is considered a necessary element of the equipment of the room of the schoolboy, student, office. Behind him it is convenient to work with a computer, office equipment and documents. But only if the product is chosen correctly in size. And here the opinion of an expert will not be superfluous.

What dimensions are relevant?

There are standard settings for spatial characteristics for a desk. They are obtained as a result of joint research of physicians and designers. The first determine these parameters, taking into account the possibility of eliminating overvoltage during work, damage to posture and maintaining normal blood circulation, especially in the lower extremities due to many hours of sitting in one position. And the latter in their recommendations proceed from the position of ergonomics and ease of use. Therefore, it is advisable to pay attention to the table of just such sizes:

Height - about 75 cm;
Width from 120 cm;
Depth - 80 cm.

The first parameter is the most important, because thanks to it a person keeps his back straight when working with documents, and the information displayed on the computer monitor is just at eye level. The width and depth are determined taking into account the free space available in the room and the functionality that is planned to be placed on the table. For one monitor or laptop, 80 cm will be enough, but if you need other office equipment - a printer, scanner, shredder, etc., then at least 120 cm, and preferably 150-160 cm. Plus, you should leave some space for working with documents.

Equipment features

When choosing a desk for dimensional characteristics, it is also worth considering the number of people who will sit at it. If the design implies the presence of an attached pedestal for equipping a workplace for another employee, then the length of the table must be at least 160 cm at the rate of 120 cm for the main working area plus 40 cm for the side cabinet. Employees sitting opposite each other need furniture with a depth of 90 cm. This will allow you to place monitors. Depending on the specifics of the work, the placement of additional elements of the table configuration is also selected:

The sliding shelf for the keyboard should be at a distance of 10-15 cm below the tabletop, which will allow the hands to freely type;
The add-on for the monitor should not be higher than 10-12 cm, as this will allow you not to get tired of your eyes when long work with information on the screen;
The stand for the system unit must be placed at least 10-15 cm from the floor, which will prevent overheating.

The presence of additional cabinets, drawers and shelves is only welcome if it does not restrict the user's movements.

Is it difficult to pick?

When choosing a desk, you should understand that designs for children and adults are presented in assortment. Designers recommend correcting the difference in sizes:

Architectural solutions for the premises;
Compact and comfortable chair;
Removable elements.

This will allow you to pick up one table for all occasions. And save money when choosing furniture for a schoolchild, student or worker by purchasing only one item.

Perhaps there is no such area human life, which would not yet feel the influence of modern high technology. 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.

Given the role computer technology in medicine, we can confidently talk about their contribution to a real improvement in the quality and length of life.

Given the role of computer technology in medicine, we can confidently talk about their contribution to a real improvement in the quality and life expectancy. Virtual modeling of the course of diseases is widely used; special programs calculate the optimal formulas for new medicines etc.

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, do not violate temperature conditions technical work.
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 spends much more energy, and thus tire quickly.

Correct posture at the computer desk

The concept of posture refers to one or another independent position 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.

At correct 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 for 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.
