The sex difference in body size and proportion was examined by comparing males and females of the same range of stature (170-179cm). Under the condition that there was no sex difference in stature, weight and Rohrer index, it was found that males were larger in sizes of the upper part of the trunk and upper limb girth, while females were larger in sizes of the pelvic part, length and girth of the lower limb, and subcutaneous fat thickness. No sex difference was observed in upper limb length. It was confirmed that on condition of the same stature, the lower limb was longer in females than in males.
