What Makes a Face Symmetry Test Worth Using
Every face symmetry test does the same basic thing: it finds points on your face, pairs each one with its twin on the other side, and measures how far apart they land when the face is mirrored. The differences between tools are in the details, and the details decide whether the number means anything.
- How many points it measures. 68 points (the classic dlib layout) covers the eyes, brows, nose, mouth and jaw outline. 468 to 478 points (Google's MediaPipe face mesh) also covers the cheeks and the full contour, so small differences show up.
- Whether it corrects for head tilt. A head turned a few degrees reads as asymmetry. Good tests fit the mirrored face back over the original or reject turned photos.
- What the score is compared with. "78/100" means nothing on its own. A score ranked against real faces tells you where you actually stand.
- Where your photo goes. Some tests run in your browser and never upload anything; others send the photo to a server.
- Whether it is really an attractiveness score. Several tools blend symmetry into a beauty rating. Symmetry and attractiveness are only weakly linked, so a pure symmetry test is more honest.
The Six Tests, Compared
Disclosure: Ollie's test is our own. For the other five we describe what each tool says about itself on its own page; we haven't audited their code.
1. Ollie Face Symmetry Test. Ollie's test maps 478 points with MediaPipe in your browser, so the photo never leaves your device. It fits the mirrored face back over the original to cancel out a tilted head, rejects photos turned too far to the side, and ranks your result against 3,898 straight-on photos of real faces: a score of 70 means more symmetric than 70% of them. You get an overall score plus the eyes, brows, nose, mouth and jaw, and a slider showing your face mirrored each way. It does not rate attractiveness. Your first test each day is free without an account, and a free account adds 5 credits. It also works as a free ChatGPT app and Claude connector, with no sign-in.
2. FaceSymmetryTest.org. facesymmetrytest.org says it uses 468 facial landmarks through TensorFlow.js and processes everything locally in your browser, with no login. That makes it a strong private option.
3. Face-Symmetry-Test.com. face-symmetry-test.com says it places 68 landmarks and measures seven feature pairs against your facial midline, discarding the photo after measurement. Fewer points, but a clear per-feature breakdown.
4. FaceShapeTool. faceshapetool.com says it gives a 0 to 100 symmetry score with the eyes, brows, nose and jawline scored separately, alongside facial thirds.
5. Fotor. Fotor's face symmetry test is part of a larger photo editor. You upload a front-facing selfie and get a score, with other categories such as beauty and skin smoothness offered next to it, so it leans towards a looks rating.
6. FaceSymmetryChecker. facesymmetrychecker.com says it gives percentages for the eyes, eyebrows, nose, mouth, ears and cheeks, from an upload or your camera.

Which One Should You Use?
- For a score that means something: pick a test that ranks you against real faces. Ollie says exactly what it compares you with (3,898 straight-on photos of real faces); on other tools, look for the same before trusting the number.
- For privacy: pick one that runs in your browser. Ollie and FaceSymmetryTest.org both say the photo never leaves your device.
- For a feature-by-feature breakdown: Ollie, Face-Symmetry-Test.com, FaceShapeTool and FaceSymmetryChecker all score features separately.
- Avoid: treating any of these as a beauty verdict. A symmetry score says how closely your two sides match in one photo, nothing more.
How to Get an Accurate Score on Any Test
The photo matters as much as your face. A head turned a few degrees, a phone held close enough to bend your features, uneven light or a lopsided smile all shift the points and lower your score.
- Hold the camera at eye level and at arm's length, or use the rear camera with a mirror.
- Look straight into the lens with a relaxed, closed mouth.
- Face a window or other even light, so neither side is in shadow.
- Pull hair off your face and take off glasses.
- Take two or three photos and compare: if the scores differ a lot, the photos are the problem, not your face.
Nobody scores perfectly. In Ollie's 3,898 reference faces, even the most symmetric still have measurable differences between the two sides. For what the research says about symmetry and looks, read face symmetry and AI recognition and the golden ratio, myth vs evidence.
