What is φ (Phi)?
The Golden Ratio ≈ 1.618 is a mathematical constant appearing in nature, art, and architecture for over 2,400 years — from the Parthenon to Da Vinci’s works.
Eye Proportions
Ideal eye spacing = 1.618× a single eye’s width. The distance from outer eye to outer eye should relate to nose width by φ.
Nose & Mouth
Mouth width should be ~1.618× nose width. Nose width to nostril width follows the same φ proportion for harmony.
Face Length/Width
A face length approximately 1.618× its width is considered ideally proportioned — the foundational golden ratio measurement.
Facial Thirds
The face should divide into 3 equal horizontal zones: hairline→brow (upper), brow→nose base (mid), and nose base→chin (lower).
Perfect Score
A 100% score is extraordinarily rare. Most top models score 88–94%. The ratio is a guide to harmony, not an absolute beauty verdict.
