Check classic face, nose, mouth, and lower-face proportions in one free marked result. Discover your exact percentage match with the Divine Proportion (Phi = 1.618).
For highest geometric precision: keep your face upright, neutral expression, mouth gently closed, and look straight into the camera.
The Golden Ratio, represented by the Greek letter Phi (Φ ≈ 1.618), has captivated mathematicians, artists, and anatomists since ancient Greece. Leonardo da Vinci extensively mapped these proportions in 'De Divina Proportione' and his famous Vitruvian Man.
In modern aesthetic medicine and facial plastic surgery, Dr. Stephen Marquardt and numerous peer-reviewed studies have investigated how closely human perceptions of attractiveness correlate with Phi proportions in face height-to-width, nasal-to-lip height, and mouth-to-eye width.
While high Phi concordance often correlates with perceived classical symmetry, character and beauty thrive on natural variation—each face possesses unique harmony.
Everything you need to know about the Golden Ratio in facial aesthetics.
The Golden Ratio is the mathematical constant 1.618. In facial aesthetics, it refers to whether the ratio of key dimensions (such as face length to width, or mouth width to intercanthal distance) equals approximately 1.618.
