The development of sizing systems for Taiwanese elementary- and high-school students

[[abstract]]This study aims to develop sizing systems for Taiwanese elementary- and high-school students. A total of 7800 students' anthropometric data covering their ages from 6 to 18 years for both genders were used in this study. A two-stage cluster analysis was performed for the classification of figure types. The size charts were developed based on the morphological characteristics of each figure type. Twelve sizing systems were established systematically by age group (elementary-, junior high-school and senior high-school students), gender (male and female) and garment type (upper and lower garments). The coverage rate of the developed sizing systems was over 85%, and the number of sizing groups of each system was less than 36. In addition, an index of aggregate loss of fit was used to validate the size charts, and the results showed that all the developed size charts had a good fit. Moreover, the developed sizing systems were compared with the Korean Standards, and a similar trend was found. Relevance to industry: The developed sizing systems were based on the most recent and complete anthropometric database in Taiwan. The proposed method can be used to develop sizing systems for different populations. The results obtained provide important references for the design and production of different clothing.[[fileno]]2020405010023[[department]]工工
