The proportion of a standard human body is 1/8 for head height, 1/4 for shoulder width, arm width equal to body length, armpit width equal to hip width, breast flush with shoulder angle, thigh front thickness equal to face thickness, and kneeling height reduced 1/4.

As for the ratio of upper and lower parts: it conforms to the golden section law, that is, the ratio of body length above navel to below navel is 0.6 18: 1. Suggestion: The most standard ratio: the ratio of body length above navel to body length below navel is 0.6 18: 1, but this is the most standard.

The real proportion is actually related to many factors such as human growth and development, nutritional status, growth environment, heredity, etc. As long as the proportion does not affect human health, it is normal.

Standard figure calculation ratio calculation ratio: height/head length = head and body (this is the so-called height ratio standard). For example, if your height is 159cm and your head length is 20cm, then 159 (height) ÷20 (head length) =7.59 (head and body). After rounding, you are the standard 8-headed body! ?

Because everyone's skeleton and body shape are different, if the difference between the calculation results is 0.5, it is within the range of qualified standards! Standard weight (kg)≈ (height-100 cm) × 0.9 means B≈(A- 100)×0.9 1. If b > is above the standard, it means that the weight is heavy, and it is recommended to exercise or lose weight. 2. If B is above the standard, it is lighter, so it is recommended to pay attention to diet and exercise. ?

Upper body: lower body ≈ 1: 1.6 18, that is, C: D ≈1:1.618 is the standard body shape. 3. If c: d <1:1.54666666
