How the symmetry test works
After the on-device model places 478 landmarks, the test rotates the image so your eyes are level, then fits a straight center line through 28 points that run down the middle of the face, from the forehead through the bridge and tip of the nose to the chin. Each of 50 left-side points is reflected across that line and compared with its right-side partner. The average gap, as a percentage of cheekbone width, becomes the asymmetry figure; the symmetry score converts it to a 0–100 scale, where a perfect mirror image would score 100.
Regional scores use the same method on subsets: the eye corners and eyelids, the brows, the mouth and lips, the nose wings, the cheeks and the jawline. They show where most of the difference sits.
What is a normal symmetry score?
No face is perfectly symmetrical. Small differences in eye height, brow shape, nose direction and jaw width are normal, and a smile is rarely even on both sides. In photos, average offsets of roughly 1.5% to 4% of face width are common, which this test reports as scores from the 70s to around 90. Your result reflects the photo as much as the face: turning your head even a few degrees moves the far side’s points inward.
Does facial symmetry make a face more attractive?
Research finds a link, but a modest one. Reviews of the evidence (Rhodes, 2006) report that more symmetrical faces are often rated slightly more attractive, while artificially perfect faces made by mirroring one half can look odd. Averageness, skin, expression and familiarity also matter. Our facial symmetry guide summarizes what studies have and have not shown.
Tips for a fair symmetry reading
- Look straight into the lens with the camera at eye level.
- Relax your face; smiles, raised brows and squinting are rarely symmetrical.
- Pull hair back so the jaw and forehead edges are visible.
- Use even lighting so shadows do not hide one side.
The result also tells you which half of the photo sits slightly wider of the center line. If you have a favorite photo side, that is one way to compare it with the other.
