Abstract: When an enterprise produces school uniforms, it often takes the clothing specification and size based on the students’ height and weight as the basic information. This kind of method relying on the experience, it is impossible to meet the development requirement. Characteristics of the male college students’ bodies in Liaoning Province was analysed in this pape, based on the survey of 270 male college students’ bodies, in which 15 body measures were taken. Through the regression analysis of these data, the results shows that the height and weight have influenced on waist girth significantly, and an binary linear equation about height and weight is established. Base on traditional series size design, the relationships between height and length, waist girth and width were significant, and then a equation of a degree is established. In this way, a reasonable uniform series size of male college students can be obtained, which will fit the figure better.
