The desks and chairs for single students in grades 1 and 1-2 are 67CM high, 60CM long and 45CM wide respectively.
2. The desks and chairs for single students in grades 3-4 are: 70CM high, 60CM long and 45CM wide.
The desks and chairs for single students in grades three, five and six are 73CM high, 60CM long and 45CM wide respectively.
4, junior high school stage: the height of junior high school is a time of rapid development, so its height is the same as that of normal desks and chairs, generally controlled at 75-80CM. For example, the length and width of the whole student desk and chair have not changed much, only the height is different.
5. High school stage: The specifications of student desks and chairs are generally 75-80CM high, 45-50 cm wide and 60- 120CM long, and the length will be different.
6. University stage: The desks and chairs used by students in universities are very different from those used in primary and secondary schools, which also makes many people misunderstand. Nowadays, there are ladders, tables and chairs in universities, and they are all fixed. Their height and width are not much of a problem, mainly because of their length. In college, eight to ten people can work continuously at the same time. A church can seat two or three hundred people, and the tables and chairs are installed in steps, but there is also a problem that the students in front are blocked.
The National Basic Standards for Physical Education and Hygienic Conditions in Schools stipulates the standards for placing desks in classrooms.
1. The front edge of the desk in the front row of the classroom should be more than 2 meters away from the blackboard.
2. There should be a longitudinal walkway not less than 0.6 meters wide between desks in the classroom, and a transverse walkway not less than 0.6 meters should be set behind the classroom. The back edge of the back table is not more than 9 meters away from the blackboard.
Every student in the classroom should have a seat, and each classroom should be equipped with at least two different types of desks and chairs.
4. The illuminance of desks and blackboards should be no less than 150LX and 200LX respectively, and the illuminance distribution should be uniform. Artificial lighting should be supplemented when natural lighting is insufficient.
