Face Symmetry Test
How symmetric is your face? Upload a straight-on photo and see how you compare with 3,898 real faces.
Ollie's face symmetry test maps 478 points on your face, mirrors one side onto the other, and measures how far they miss. Your result is ranked against 3800+straight-on photos of real faces, overall and for your eyes, brows, nose, mouth and jaw. It's free, runs in your browser, and your photo is never uploaded.
How the face symmetry test works
- 1
Map the face. Google's MediaPipe face model places 478 points on your face, in your browser. Nothing is sent to a server.
- 2
Mirror it. Each point on one side is paired with its twin on the other. The face is flipped and laid back over itself in the best possible fit, which cancels out a tilted head.
- 3
Measure what's left. How far the paired points still miss each other is your asymmetry, overall and for your eyes, brows, nose, mouth and jaw. It's ranked against 3800+ straight-on photos of real faces, so 70 means more symmetric than 70% of them.
How to get an accurate result
- Look straight at the camera, with your head level. A turn of a few degrees shows up as asymmetry.
- Hold the phone at arm's length, or use the rear camera. Close-up selfies stretch the middle of the face.
- Keep a neutral face. Smiles and raised eyebrows are rarely even on both sides.
- Use soft, even light from the front, and pull hair back from your face.
Common questions
How do I test my face symmetry?
Upload a clear photo where you look straight at the camera, then press Test my symmetry. Ollie maps 478 points on your face, mirrors them, and shows how symmetric you are compared with real faces, with your face mirrored left-to-left and right-to-right.
Is anyone's face perfectly symmetrical?
No. Every face is a little asymmetric. In the 3800+ reference photos, matching points on the two sides typically miss each other by about 2% of the distance between the eyes, and even the most symmetric faces are never at zero.
What is a good face symmetry score?
Anything from about 40 to 60 is average. Above 80 means your face is more symmetric than four in five faces. A low score usually says more about the photo (a slight head turn, a lopsided smile, wide-angle selfie distortion) than about your face.
Does face symmetry mean you're attractive?
Only a little. Studies find people rate slightly more symmetric faces as a bit more attractive, but the effect is small next to things like skin, expression and familiarity, and perfectly symmetric composites often look odd. That's why this test measures symmetry and does not rate looks.
Why does my score change between photos?
The camera matters as much as your face. Head turns of a few degrees, a phone held close to your face, uneven lighting and expressions all shift the points. The test rejects photos turned more than 6° to the side. For a fair score, use a straight-on photo at arm's length with a neutral face.
Is my photo stored?
No. The whole test runs in your browser and your photo never leaves your device. The share image is drawn on your device too.
