How to calculate the body proportion?
The graphic scale is calculated as follows:

Height and bust index = (chest circumference/height) × 100: the average Asian male is 5 1.76, and the average Asian female is 52.35; The average male in Europe and America is 56.46, and the average female in Europe and America is 55.67.

Height waist circumference index = (waist circumference/height) × 100: the average for Asian men is 42.79, and the average for Asian women is 41.34; The average male in Europe and America is 47.84, and the average female in Europe and America is 44.53.

Height and hip circumference index = (hip circumference/height) × 100: the average of Asian males is 52.07, and that of Asian females is 57.78; The average male in Europe and America is 56.03, and the average female in Europe and America is 59.34.

Men and women of the same nationality are correlated in height, weight and other parameters, which can be converted to each other. Japanese scholar Masamitsu Oshima calculated the conversion coefficient of female figure from male data (excerpt): chest circumference coefficient is 90%, waist circumference coefficient is 89%, and hip circumference coefficient is 102%.

Waist-to-hip ratio = waist circumference/hip circumference: the average for Asian men is 0.8 1. , while Asian women average 0.73; European and American men average 0.85, and European and American women average 0.75.

The figure proportion is one of the windows to measure the figure from many angles and plays an important role in the image. Body proportion involves leg-to-body ratio, head-to-body ratio, waist-to-hip ratio, shoulder-to-hip ratio, height measurement index and so on.

From the perspective of gender differences, men's shoulders are wide and hips are narrow, while women's shoulders are narrow and hip breadth; Men have a broad chest and a thick trunk, which looks developed above the waist, while women have wide hips and full thighs, which looks developed below the waist; Male fat is mostly concentrated in the abdomen, and female fat is mostly concentrated in the buttocks and thighs; The position of male body center of gravity is relatively higher than that of female body center of gravity.

Men's waistlines are lower and women's waistlines are higher. Leg length is expressed by hip height or height MINUS sitting height: at the same height, female legs are longer than male legs; However, because the leg-to-body ratio is positively correlated with height, the greater the height, the greater the leg-to-body ratio; Therefore, the average leg-to-body ratio and average leg length index of Mahalanobis's trunk are slightly larger for men than for women, and the leg-to-body ratio is slightly larger for men than for women.
