1. Leg to body ratio: the ratio of leg length to height.
Formula: Leg length = height-sitting height, and leg-to-body ratio = (leg length/height) × 100.
2. Waist-to-hip ratio (WHR) is the ratio of waist circumference to hip circumference, which is an important indicator to judge central obesity, an effective clue to predict women's fertility and an important measure to evaluate women's charm.
Formula: waist-hip ratio = (waist circumference/hip circumference)
3. head-to-body ratio
The proportion of eight heads and bodies in ancient Greek statues is recognized as the most beautiful. In fact, except in some parts of Europe, it is difficult to find people with eight heads in life, usually 7.5 heads, while people in many parts of Asia only have seven heads. Except for a few people, such as Robert Pershing Wadlow and manute bol, what we usually call "Jiuti" is actually not the case.
Head height: the vertical distance from the top of the head to the submental point.
Formula: head-to-body ratio = height/head height.
4. Shoulder-hip ratio
Research shows that women think men with wide shoulders and narrow hips are the most attractive.
Testosterone, estrogen and progesterone affect the development of gender-related physical characteristics, such as shoulder-hip ratio and waist-hip ratio of men and women.
Formula: Shoulder-hip ratio (SHR) = maximum shoulder width/hip breadth.
Extended data:
Gender differences and preferences
Gender difference
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.
Male and female preferences
(1) In a study, young women aged 18 ~ 30 were asked to describe the figure of their favorite men, who generally tend to have slender legs, narrow shoulders and narrow hips and a V-shaped figure; I hate hip breadth's short legs and narrow shoulders. I have a pear shape (S.J.Korn, 1975)[6]? .
Actor Tom Hanks asked his friend rob reiner what women are pursuing nowadays. Lai Na gave the answer in the movie Sleepless in Seattle 1993: "Developed chest muscles and narrow buttocks."
(2) In a series of cross-cultural studies, Singer showed men female sketches with different waist-hip ratios. In some sketches, the waist-hip ratio of women is 0.7, some are 0.8 and some are 0.9. The experimenter asked the subjects to circle the pictures they thought were the most attractive. In all the selected samples (including Africa, Brazil and the United States), men of different ages think that women with a waist-hip ratio of 0.7 are the most attractive.
