The requirements of national standards for students' desks and chairs are: the height is between 1.60m and 1.85m, and the weight does not exceed 3kg. In terms of size, the distance from thigh to calf is 28 cm, the distance from elbow to wrist is 23 cm, and the diameter of sole is more than 25 cm. If the height is high, there is a certain thickness at the knee joint.
According to the latest standards of the Ministry of Education, the standard size of the desk for primary school students is 60cm x 120cm, and there is a slit on the surface of the desk, which is 6-7cm deep and 4-5cm wide. The height of the table is required to be 62 cm from the ground. The two metal screws on the legs of the table should not be damaged externally, and the legs of the table should be firmly connected.
The standard size of the chair is 34cm x 50cm, and the height is 45cm. There is a crack on the surface of the chair, and there should be two metal screws under the seat plate to ensure that the legs of the chair are firmly connected and not damaged.
The size of the chair seat requires that the distance between the seat plate and the support plate should not be less than 9 cm, so as to ensure that the height of the seat plate is consistent and the internal support is firm, which is beneficial to the sitting posture of primary school students, thus reducing unnecessary dangers.
Matters needing attention
Proper use of chairs can improve learning efficiency and avoid sedentary; Tables and chairs should be placed correctly so as not to affect the learning effect; It is not advisable to sit immediately after a meal and take a break before doing other activities; Seat height is moderate, not too high or too low; Books should not be placed on the table, so as not to hinder the line of sight; Please don't neglect the safety design on the armrests of children's seats.
National standard for student desks and chairs
The national standard for students' desks and chairs is formulated according to the Standard for General Classroom Equipment promulgated by the national education department. The standard puts forward specific requirements for all teaching supplies used in schools, including: desktop height, chair size, drawer width, etc. The national standard for student desks also stipulates the distance between chairs and benches and the included angle between chairs and the ground. If you want to adjust these parameters, you need to calculate according to the corresponding formula.
The national standards and size requirements of student desks and chairs are consistent. This has brought great pressure and challenges to the school. At present, China's Ministry of Education is formulating new standards to adapt to this development trend. I believe that in the near future, primary and secondary schools will have new facilities that meet international standards.
