Asymmetry
Mean mismatch of 17 mirrored landmark pairs, as % of face width. Lower is better.
Reference range
| Male | Female | |
|---|---|---|
| Range scored 10/10 | 0.00% to 1.50% | 0.00% to 1.50% |
Outside the range the score falls off smoothly: about 6/10 at 1.20% 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.
What can fool it
Head turn and lens distortion inflate it. Shoot straight on from 1.5 m or more.
Where it counts
It feeds the Features pillar (eyes, symmetry and skin), which is 25% of the overall Mirrorline score.
