Abstract

In an effort to establish a criterion on the size of desk and chair suitable for middle and high school students, measurement has been taken of height, sitting height, and knee height for 2,090 male and 1,920 female students during the period from March 15 to April 30, 1971, and the size of desk and chair which are currently used at the school has also been measured.
Followings are the summary of the findings:
1. For students in the same grade, the differences by age in measurements on height, sitting height, and knee height were not substantial as compared with that by class which implies that the criteria for the size of desk and chair may have to be established on the basis of physical measurements of students by grade rather than by age.
2. The standard heights of desk and chair considered to be most suitable for the students are:
Middle School High School
Desk Chair Desk Chair
For Male Students: 71.0㎝ 44.3㎝ 77.4㎝ 48.1㎝
For Female Students:69.7㎝ 42.9㎝ 72.0㎝ 44.1㎝
3. The actual heights of desk and chair are:
Middle School High School
Desk Chair Desk Chair
Male Students: 68.6㎝ 37.5㎝ 71.3㎝ 39.8㎝
Female Students: 69.1㎝ 39.1㎝ 70.9㎝ 38.5㎝
4. The proportion of students who complained of their desk and chair showed a remarkable increase as the size of their currently using desk and chair deviate from the standard given in (2). as indicated below.
For Desk:
Deviation from criterion lower by:
1㎝ 3㎝ 5㎝ 7㎝ 9㎝ 11㎝
Per cent complained:
9.8% 17.5% 62.0% 72.9% 82.4% 87.5%
For Chair:
Deviation from criterion lower by:
1㎝ 3㎝ 5㎝ 7㎝ 9㎝ 11㎝
Per cent complained:
9.1% 11.5% 41.0% 61.5% 63.2% 94.3%
5. It was observed that the most of the desk and chair currently being used by middle and high school did not meet the size of the standard.
6. Assuming that the standard size with allowance of ±3㎝ can be considered as acceptable for students, the proportion which would enjoy the suitable desk and chair when the standard size were used will be as follows:
Proportion which would enjoy the suitable desk
Male Student Female Student
Middle High Middle High
With standard size: 49.7% 63.7% 58.2% 77.0%
With current size: 43.8% 17.1% 57.6% 72.6%
Proportion which would enjoy the suitable chair
Male Student Female Student
Middle High Middle High
With standard size: 63.8% 80.6% 82.6% 88.6%
With current size: 10.2% 1.1% 35.8% 8.6%
This results indicates clearly that the size of currently using desk and chair should be corrected to meet the standard.
7. Of a total of 317 middle schoolboys, 51.4% of them suggested the removal of the foot supporting bar of the desk and of 348 high schoolboys, 70.7% did the same.
