The length of the fist and the sole of the foot are very close, so when you buy socks, you only need to wrap the bottom of the socks around the fist to know whether it is suitable. Height is about 7 times the length of feet; The wrist circumference is exactly half of the neck circumference; The length of the arm is exactly equal to the height; The widest part of the shoulder should be equal to the height of 1/4 ... When the height of an adult is equal to 8 times of the head length, the figure is more beautiful, while the height of many people is equal to 7.5 times of the head length.

1870, Belgian mathematician Quetta Ritter published Anthropology, which gradually formed the science of anthropology. For example, h stands for height. According to the approximate anthropometric values, the eye height is 0.9H, the acromion height is 0.8H, the fingertip height is 0.4H, the shoulder width is 0.25H, and the calf height is 0.25 h. The appropriate table height is 0.4H, the seat height is 0.55H, and the upper limb height is1.2 h. Of course, different people, different nationalities and different regions have different H values. Later, scientists studied the relationship between human height and weight, and found that there is a certain proportion between the height and weight of normal people. One way to estimate the ideal weight is that the height (cm) minus 105 (constant) equals the ideal weight. Or 0.36 (constant) multiplied by height (cm) equals the standard weight of men (kg); 0.34 (constant) times height (cm) equals the standard weight of women.
