Abstract： To improve the wearability and fit of children's hand products，this study took preschool children in the Henan region as the research subject and measured 27 hand dimensions of 480 children aged 3-6 years old in the Pingdingshan Area by using electronic digital calipers and soft measuring tapes. On this basis，we analyzed the characteristics of children's hand shapes using statistical methods such as analysis of variance，correlation analysis，and factor analysis. We also applied K -means cluster analysis to classify preschool children's hand shapes. The results indicated that preschool children's hand shapes can be characterized by nine size feature indicators and four morphological feature indicators. Based on size features，girls′hand shapes can be classified into small， proportionate，and wide types，and boys‘hand shapes can be classified into short and stocky types in addition to these three types. According to morphological features，boys' and girls′ hand shapes can be divided into V，H，and O types.By combining with the national standard GB/T 26159—2010 Hand Sizing System of Chinese Minors，the hand sizes of boys aged 3-4，5，and 6 can be designated as sizes 110/50（H），120/55（H），and 130/55（O）， respectively.For girls，the corresponding sizes are 110/50 （V），120/55（H），and 130/55（O）， respectively. By studying the analysis and classification of hand characteristics in preschool children， valuable insights can be provided for the design and development of children's hand-related products.
