A table is a very common piece of furniture, with a table top and three or four legs as support below. Tables are used to put things. Different tables have different uses, such as eating, writing or playing cards, mahjong. Later, with the increase of people's demand, the types of tables became diverse. But every kind of table has a fixed standard height. When it reaches the corresponding height, it is most convenient for people to use it. Today, let's talk about the standard height of the table.

The correct height of tables and chairs should enable people to maintain two basic verticals when sitting: First, when their feet are flat on the ground, their thighs and calves can be basically vertical. At this time, the front edge of the seat cannot press the lower thigh plane. Second, when the arm hangs naturally, the upper arm is basically perpendicular to the forearm, and the height of the desktop should just touch the lower plane of the forearm. In this way, people can keep the correct sitting posture and writing posture.

For the height of the table, the state has set standards.

Chinese national standard: the height difference between tables and chairs should be controlled within the range of 280 ~ 320mm. The national standard stipulates the height of tables and chairs.

Among them, the height size standard of dining table furniture can be 700mm, 720mm, 740mm and 760mm;

The height of chairs and stools can be 400mm, 420mm and 440 mm. In addition, the standard size of tables and chairs is stipulated, and the height difference between tables and chairs should be controlled within the range of 280 ~ 320 mm.

Height of writing desk: If the height of desk and chair is unreasonable, it will directly affect people's sitting posture, which is not conducive to users' health. To this end, the national standard also stipulates that the height of the desk under the desktop is not less than 580mm, and the space width is not less than 520 mm. This is to ensure that people can have enough space to put their legs when using it.

Height of computer desk: The maximum height of computer desk cannot exceed 70cm. Improper design of computer desk will lead to low back pain, neck muscle fatigue or strain, hand muscle tenosynovitis, vision loss and other diseases.

According to experts, whether it is a computer desk or a computer desk, the height of the keyboard and mouse should be the same as or slightly lower than the elbow when sitting. The top of the monitor should not be higher than the horizontal line of sight of the sitting eyes, otherwise the vision will be reduced.

In China, the heights of computer desks, writing desks and desks are generally higher. Experts suggest that manufacturers reduce the height of the computer desk, and it is best to design a foldable elbow board on the computer desk. Consumers can also request a computer desk with a slightly smaller size when purchasing.

The table is so ordinary that many people ignore it. In fact, it has irreplaceable importance. Eating requires a dining table, studying requires a writing desk, playing mahjong requires a mahjong table, and playing computer requires a computer desk. And the height of all kinds of desks should meet people's needs. If they don't do this, people will feel uncomfortable. Moreover, if the desk is too high and the chair is too low when studying, it will become a posture on the desktop. After a long time, it may not only lead to myopia, but also bend the spine.
