For the height of tables and chairs, the standard height of tabletop furniture can be 700mm, 720mm, 740mm, 760mm, four specifications; the seat height of stool furniture can be 400mm, 420mm, 440mm, three specifications. In addition, the standard size of the table and chair is specified, and the height difference between the table and chair should be controlled within the range of 280 to 320 mm.
This will enable people to maintain correct sitting and writing postures. If the height of the table and the chair feet are reasonably mismatched, it will directly affect the posture of the sitting person, which is not conducive to the health of the user. In addition, the space under the table board is not less than 580mm, and the space width is not less than 520mm.
Whether it is the height of the desk legs or the height of the keyboard and mouse on the computer desk, it should be as high as or slightly lower than the elbow of a person in a sitting posture. And the top of the monitor should not be higher than the eye level of the sitting position, otherwise it will cause vision loss.
In Japan, the standard height of a desk before 1971 was 740mm. Due to the repeated occurrence of various occupational diseases, Japan comprehensively revised the standards for office appliances in 1971, respectively stipulating 70 cm and 67 cm as the standard height of men's and women's desks, thereby greatly reducing fatigue. In the UK, the current recommended desktop height is only 710mm.
To sum up, the height of legs between 70-75cm is most appropriate.
