  • No sunglasses or heavy filter

Every face is asymmetric. The useful question is where, and by how much. This tool compares ten mirrored pairs of landmarks, from the eye corners to the jaw, and reports the difference in each pair as a fraction of the distance between your pupils.

How it works

Three steps, no upload

The result is a measurement, not a verdict. A small difference is ordinary. The detail rows show which pairs differ most, so you can see whether the reading comes from the eyes, the mouth or the jaw.

  1. 1

    Use a straight-on photo

    Symmetry is sensitive to the angle of the camera. A photo taken slightly from one side will read as asymmetric even when the face is not.

  2. 2

    The tool mirrors the landmarks

    It measures each pair's distance from the face's vertical axis and the height difference between the two points, then scales the result by the pupil distance.

  3. 3

    Read the index and the pairs

    The index runs from 0 to 100, where 100 is a perfectly mirrored mesh. The three largest differences are listed underneath, in plain language.

Questions

Face symmetry test FAQ

What is a normal symmetry score?

There is no published norm for this index. It is this site's own scale: every 1% of pupil distance of average mismatch between the pairs costs 5 points, and the full formula is on the method page. Compare a reading with your own photos taken the same way, not with other people. A lower number describes the mesh; it is not a problem to fix.

Does the camera angle affect the result?

Yes, more than anything else. Even a small turn of the head changes the distances. The tool checks the head pose and asks you to retake the photo if it is too far off center.

Is symmetry related to attractiveness?

It appears in some research on how people judge faces, but the effect is small and contested. This tool measures geometry and does not claim to explain attraction.

Can I use the same photo as the face shape tool?

Yes. If you have already measured a photo in this browser session, the symmetry tool can reuse the landmarks without another upload or another model run.
