Face I 1. Three courts The length of the face is divided into three equal parts, from the hairline to the eyebrow line is a court, from the eyebrow line to the bottom of the nose is a court, and below the bottom of the nose is a court. 2.Five eyes Taking the length of the eye shape as a unit, the width of the face is divided into five equal parts from the left hairline to the right hairline. 3.Golden trilinear ratio Cheek face width: Temporal face width: Mandibular angle width ≈ 0.8:1:0.6. Face II 1.Bottom of nose point The division point between the hairline and the bottom of the jaw from the upper 1/3 to the lower 2/3. 2.Labial bead point The point between the bottom of the nose and the bottom of the jaw from the upper 1/3 to the lower 2/3. 3.Mouth corner point The distance between the two mouth corner points is 1.618 times the distance from the corner of the mouth to the mandible. 4.The midpoint of the maxillofacial groove The division point between the bottom of the nose and the bottom of the jaw between the lower 1/3 and the upper 2/3. Nose 1.Nasal forehead angle The size and position of this angle is very important to the appearance, 120-130° is appropriate. 2.Nasolabial angle The size and position of this angle is very important to the appearance, 120-130 ° is appropriate. 3.Nasal tip angle 85-90° is the most ideal angle. 4.Nose length The straight line distance from the nasal root point to the nasal tip point is generally 60-75mm. 5.Nasal tip The ideal height is 1/3 of the nasal length, about 26mm for men and 23mm for women, with a spherical shape and an oval nostril slanting toward the nasal tip, with bilateral symmetry.
