90–100
Very symmetric
The two halves of your face match closely in this photo. The mirrored images should look almost the same.

Face Symmetry Test
How symmetrical is your face? Measure it, then see it mirrored.
This free face symmetry test compares 220 mirrored landmark pairs on one photo, scores your facial symmetry from 0 to 100 and rebuilds your face from each half. It runs in your browser, so the photo is never uploaded.

The method
How the face symmetry test works
Most symmetry checks flip a photo down the middle of the image. This face symmetry test finds the middle of your face instead, so a slightly off-centre or leaning photo still gets a fair reading.
- 1
Find 478 landmarks
An on-device face model places a mesh of 478 points on your photo: eyes, brows, nose, lips, jaw and the outline of the face.
- 2
Undo the head turn
The mesh is fitted against a template to estimate how far your head is turned, tilted and leaning, then rotated back to a front view.
- 3
Fit your midline
The face symmetry test aligns the mesh with its own mirror image. The line that makes the two halves agree best is your facial midline.
- 4
Measure every pair
220 left–right landmark pairs are compared across that midline. The average mismatch, as a share of face width, becomes your 0–100 score.
The scale
What your face symmetry test score means
A higher score means the two halves of your face sit closer to a perfect mirror in this photo.
78–89
Symmetric
A typical, even face: small differences between the halves that people do not notice in person.
62–77
Mildly asymmetric
One or two features sit differently on each side. A slightly turned head or a half-smile often causes this.
Below 62
Noticeably asymmetric in this photo
The halves differ clearly in this photo. Check the photo conditions first: head turn and expression are the usual reasons.
These are bands inside this face symmetry test. They are not population percentiles.
The mirror
Left-side and right-side mirrored faces
After the score, the face symmetry test draws two images: one built only from the left half of your photo and one built only from the right. On a perfectly symmetric face the two would be identical. On a real face they look like two slightly different people, because mirroring doubles every small difference. That is normal, and it is the clearest way to see what the number measures.
Why faces differ
What makes a face asymmetrical
Normal biology
Faces grow slightly unevenly. Sleeping side, chewing side, dental work and sun exposure all leave small differences between the halves.
Expression
A half-smile, a raised brow or a clenched jaw moves one side more than the other. A relaxed, neutral face measures best.
Camera angle
A head turned or tilted by a few degrees changes how wide each half looks. The test corrects for it, but a straight-on photo is still steadier.
Lens and light
Close wide-angle selfies distort the edges of the face, and light from one side shifts where features appear to end.
Symmetry is the most consistent predictor of perceived attractiveness in research, but it is one signal among many. It is 35% of the score in our attractiveness test, which also measures facial thirds, facial fifths and the golden ratio.
Questions
Face symmetry test FAQ
What is a face symmetry test?
A face symmetry test measures how closely the left and right halves of a face mirror each other. This one finds 478 landmarks on your photo, pairs 220 of them left to right, fits the midline of your face and scores how far each pair is from a perfect mirror, from 0 to 100.
Is the face symmetry test free?
Yes. The face symmetry test, the 0–100 score and both mirrored images are free, with no account. If you save a result you can buy a Face Report for $17.49 once, which scores eyes, brows, nose, mouth and jawline separately and adds hairstyle try-ons and a plan. There is no subscription.
Is my photo uploaded?
No. The face model runs in your browser and the photo is analysed on your own device. The mirrored images are drawn on your screen and never leave it. If you choose to save a result, only measured numbers are stored. A photo is uploaded only if you buy a Face Report and agree to it.
Is anyone’s face perfectly symmetrical?
No. Every face is slightly asymmetric: one eye sits a little higher, one brow arches more, the jaw is fuller on one side. Small differences are normal and are almost never noticed in person. A score in the “Symmetric” band already means a typical, even face.
What is a good face symmetry test score?
On this scale, 78 and above is symmetric and 90 and above is very symmetric. Scores from 62 to 77 show mild asymmetry, which a turned head or a half-smile often causes. These are bands inside this tool, not population percentiles.
Why do the two mirrored faces look so different?
Mirroring doubles every difference between your two halves, so even a typical face produces two faces that look like relatives rather than twins. A head turned a few degrees also makes one half wider in the photo. Retake the photo facing the camera straight on before reading much into it.
Does a turned head change the score?
Less than in most tools. This face symmetry test estimates how far your head is turned and tilted, rotates the landmarks back to a front view and then measures. A strongly turned photo is refused rather than scored badly, and the photo check tells you when the angle still mattered.
Can I improve my facial symmetry?
You can make the measurement fairer with a level head, even light and a neutral expression. Grooming changes how even a face reads, for example matching brow height. Adult bone structure does not change with facial exercises, and this test is not medical advice.
