Face follows the golden ratio from body to face. For human face, the aspect ratio is 0.6 18, which is the most perfect face shape. When the ratio of upper body length to lower body length is 0.6 18, it is the most harmonious figure. The ratio of teeth, ears, width and length is also about 0.6 18. The length of human digestive tract is 9 meters, multiplied by 0.6 18 is exactly 5.5 meters, which is the length of small intestine responsible for digestion and absorption.

This ratio is not only about aesthetics, but also about health. If the face is too long, people are prone to breathing problems. Because of the narrow sinuses, they often have to breathe through their mouths, which may lead to snoring or even insomnia, and may also lead to tooth deformity. If the face is too short, the mandibular joint will easily press the blood vessels, blocking part of it from flowing into the brain blood, leading to headache, which will further aggravate the muscle tension around the mandibular joint and lead to grinding teeth.
