How we measure face symmetry
- Level the face. We rotate the points so your inner eye corners are horizontal.
- Find the midline through the bridge of your nose, the base of your nose and your chin.
- Mirror 14 pairs of matching points (eye corners, brows, cheekbones, jaw corners, nostrils, mouth corners and more) across that line.
- Measure the gaps between each mirrored point and its partner, as a share of your face width, and average them.
An average gap of 2% of face width gives about 70%; an average gap under 0.7% gives 90% or more.
What your symmetry percentage means
| Score | Meaning |
|---|---|
| 90%+ | Very symmetric in this photo |
| 80–89% | Typical, clearly symmetric |
| 70–79% | Noticeable asymmetry, often from light or head angle |
| Under 70% | Usually the photo: retake it straight on in even light |
Symmetry is one part of a face
Symmetry is the biggest single factor in our attractiveness test, but proportions, eye spacing and the jaw matter too. See all eight in the face rating.
