Dimorphism · measured from a front photo
Chin : philtrum
Chin height (lower lip to chin) divided by philtrum length.
Reference range
| Male | Female | |
|---|---|---|
| Range scored 10/10 | 2.00 to 2.50 | 1.80 to 2.20 |
Outside the range the score falls off smoothly: about 6/10 at 0.30 outside it and about 1.4/10 at twice that. Ranges are compiled from facial-aesthetics research and the neoclassical canons; they describe averages of faces rated attractive, not a medical standard.
Where it counts
It feeds the Dimorphism pillar (sex-typical structural traits), which is 20% of the overall Mirrorline score.
