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.
