Face Shape Photo Calculator

Any consistent unit: millimetres, pixels, anything. Only the ratios matter.

Reading
The phi-compared proportions sit an average of 8.92% away from 1.618034. That is a geometric distance and nothing more.
Worked out from Farkas LG. Anthropometry of the Head and Face. 2nd ed. Raven Press, 1994 - definitions of the standard craniofacial landmarks and the neoclassical canons (equal vertical thirds, the horizontal fifths) and 3 other sources.
This engine works from measurements, not from an uploaded image. Measure the face on your own photo - in any unit, including pixels - and enter the numbers.
Farkas measured real faces against the neoclassical canons and found most of them do not meet them. A deviation here is normal variation, not a defect.
Proportions only. This is arithmetic on measurements you take yourself: it cannot read a photograph, it does not score attractiveness, and no result here says anything about health, character or ancestry. Facial proportions near phi or near a neoclassical canon are a geometric coincidence, not a finding.

How this is worked out

6 steps
  1. Face length : face width = 190 / 130 = 1.461538.
  2. Mouth width : nose width = 52 / 35 = 1.485714.
  3. fWHR = bizygomatic width / upper-face height = 130 / 65 = 2 (Carre and McCormick 2008).
  4. Face width / eye width = 130 / 30 = 4.333333; the neoclassical canon expects 5.
  5. Vertical thirds 63, 64, 63: the largest exceeds the smallest by 1.5873%; the canon expects them equal.
  6. Mean absolute distance of the two phi-compared ratios from phi = 8.9249%.
