Abstract
The objective of this study was to develop a school uniform sizing system with high coverage rate for middle school boys, who are in the stage of rapid growth, by identifying problems in existing school uniform sizing systems through surveys of students and uniform manufacturing companies, and analyzing juveniles' physical sizes. For this purpose. the study conducted a survey about how middle school boys choose their uniform sizes, and what complaints they have on the size of the uniforms. In addition, it was investigated what is the current state of uniform manufacturing and sizing systems through a survey of uniform companies, and the study identified problems in the size of school uniforms by comparing physical sizes of juveniles' aged 14 to 16 with the sizing systems of the companies and KS standards in 1997. Juveniles' physical data was a part of the material of the national anthropometric data in 1997. Using the two-way distribution of juveniles' height-bust girth and height-waist girth, this study established the sizing system by increasing the number of sizes for the short interval where juveniles' physical sizes are densely distributed whereas limiting the number of sizes for the long interval where juveniles' physical sizes are rarely distributed, considering the difference between companies' standard and KS' standard.
