Aim This cross‐sectional study was designed to characterize by age the ratios of limb segments length to height and extremities–trunk ratio and body proportions of southern C hinese children. Methods Data were collected from students ( n = 4715) from five school, aged 6–17 years, in the city of C hongqing. Their standing height, sitting height, arm span, forearm length, upper arm length, leg length, lower leg length, and ratios of extremities to trunk length were determined. Results Sitting height, forearm length, upper arm length, arm span, and lower leg length were highly correlated with standing height ( r > 0.9; P < 0.05). The ratio of extremities to trunk increased till about 13 years of age for both genders. Conclusions The length of extremities and their ratio to sitting height reflect regular changes of growth in C hinese children as their age, and limb segments length is highly correlated with height.
