Abstract: The purpose of the study is to solve the problem of maladjustment between children's clothing specifications and accelerated growth of preschool children. The body measurement of preschool girls of 3 to 6-year-old from the lower region of Yangtze River was carried out. Factor analysis of 13 body measurement index was undertaken and two factors were chosen. Through counting relative index, 4 representative body indexes were chosen, then through one-way ANOV and relative analysis, 4 body derived variables were determined to be clustering variables. K-means cluster was applied to classify the figure type and the optimal number of clusters was determined by Mix-F statistics, then the 447 preschool girls were subdivided into 3 types: A-type featured with small bust girth while large hip girth, V- type featured with large bust girth while small hip girth, and the H-type in between. The number and age distribution of the three types of body figure differences, by number in descending order: H- type, A-type, and V-type, meanwhile, H-type and A-type were main figure types, respectively, for 3 to 5 year-old , 5 to 6-year-old preschool girls.

Key words: preschool girl, body type classification, factor analysis, K-means cluster
