Normalize pose
The eye line is leveled before left-right differences are calculated.
Free face symmetry test
Measure facial symmetry without chasing perfection.
Compare pose-adjusted eye, cheek, nose, mouth and jaw landmarks. The analysis runs locally and explains what the symmetry index can—and cannot—mean.

What this tool measures
First correct the pose, then compare both sides.
Raw selfie symmetry is easily distorted by head tilt. The analyzer levels the eye line, estimates a center axis, and compares paired landmark distances and vertical alignment.
Natural faces are not perfectly mirrored. Expression, lighting and perspective all create visible differences, so the index is designed as a repeatable photo measurement—not a standard of worth.
Important: A single front-facing photo cannot separate anatomy from lens distortion, expression or lighting. Use the same setup when comparing results.
How to read the result
Three principles keep the numbers useful.
Expect variation
Small asymmetries are common and often contribute to recognizability.
Repeat carefully
Use the same camera distance, lens and expression for comparisons.
Common questions
A more honest way to measure.
What does a higher symmetry index mean?
It means the selected landmark pairs were more closely aligned after basic pose correction in that photo.
Why does my score change between photos?
Camera distance, expression, light direction and head angle can all move visible landmarks.
Can this diagnose facial asymmetry?
No. It is an entertainment and styling measurement, not a medical or dental assessment.
