What facial symmetry means
Facial symmetry is how closely the left and right halves of your face mirror each other. It is one of the classic markers of attractiveness and one of the things every PSL rating weighs, alongside proportions, feature quality and dimorphism. Nobody is perfectly symmetrical; the question is how close.
How to read your score
| Score | What it means |
|---|---|
| 93% and up | Highly symmetrical, unusually even |
| 87 – 92% | Symmetrical, small normal differences |
| 80 – 86% | Slightly asymmetrical, very common |
| Below 80% | Noticeable difference in this photo; check angle and expression first |
Each point of score is a quarter of a percent of face width: a 1% average gap between matching points on each side costs 4 points.
Can you improve facial symmetry?
Some of it, yes. Chewing on one side, sleeping on one side and head-forward posture all build up small imbalances, and brows, hair parting and beard shape can hide or exaggerate them. Our facial symmetry guide covers what actually works. To see how symmetry fits with everything else, run the full AI face scan, or check single features with the canthal tilt test.
Frequently Asked Questions
Is anyone's face perfectly symmetrical?
No. Every real face has small differences between the left and right side: one eye a little higher, one brow more arched, the jaw slightly wider on one side. A perfectly mirrored face actually looks a bit uncanny. What matters is how small the differences are.
How does this symmetry test work?
A face model maps 478 points on your face. We fit your facial midline through the forehead, nose, lips and chin, mirror one side onto the other, and measure how far each matching pair of points sits apart, as a share of your face width. Smaller gaps mean a higher score.
Does facial symmetry make you more attractive?
Research links higher symmetry with higher attractiveness ratings, but the effect is modest. Proportions, skin, feature shape and sexual dimorphism matter at least as much, which is why symmetry is one input in a full face rating rather than the whole score.
Why does my score change between photos?
Turning your head even slightly, a smile, uneven lighting or a close-up phone lens all add apparent asymmetry. For a fair reading, shoot straight on at eye level, about an arm's length away, with a neutral expression, and compare two or three photos.
Is my photo uploaded?
No. The face model runs in your browser and the photo never leaves your device.
