Taking the navel as the boundary, the ratio of upper body to lower body should be 5: 8, which is in line with the law of "golden section".
2. Size ratio of "8 perimeter" of standard drawing:
"8 girth" refers to chest girth, waist girth, hip girth, thigh girth, calf girth, foot neck girth, upper arm girth and neck girth.
Among them, the bust should be half of the height; Waist circumference is 20cm； smaller than chest circumference; Hip circumference is 4 cm larger than chest circumference; Leg circumference is smaller than waist circumference10 cm; The calf circumference is 20 cm smaller than the thigh circumference; Small ankle circumference and small leg circumference10 cm; Upper arm circumference is equal to half of thigh circumference; Neck circumference equals calf circumference.
3, the standard bone symmetry diagram:
When standing, the head and neck, trunk and feet should be on the same vertical line. The distance between the two acromions is equal to half a bust minus 4 cm.
Extended data
The calculation formula of standard figure is as follows: male: (height cm-80) × 70 = standard weight; Female: (height cm-70)×60 ￠= standard weight, and different age groups have different algorithms. Standard weight (kg) = age x 2+8 (7- 16 years old).
A body mass index of 18.5 to 24 is a healthy number. Body mass index = weight (kg)/height (m) squared "Calculate your body mass index and measure your figure. For example, if a friend is 1.65 meters tall and weighs 60 kilograms, his body mass index is 60/(1.65 *1.65) ≈ 22.
The gold standard of waist-hip ratio: male waist-hip ratio
