Measured, not judged
Face Symmetry Test: objective and private
How we measure it
The midline runs from the bridge of the nose to the chin. Each left-side point is mirrored across it and compared with its right-side partner. Results are averaged per feature group and expressed as a share of cheekbone width, so photo size doesn’t matter.
Camera angle changes everything
- A head turned even a few degrees makes one side look wider.
- Off-center lenses and close range add perspective distortion.
- One-sided light deepens shadows on one half.
- Expressions are rarely symmetrical — relax your face.
Take two or three photos at a fixed distance, in even light, head level — and look for differences that repeat.

What the numbers can’t tell you
Symmetry percentages describe one photo, not your face in 3D and not how others see you. “Perfectly symmetrical” half-face composites are synthetic images. Use the readout to understand why a hair part or frame looks different on one side — nothing more.
