Upload a straight-on photo and see how closely your left and right sides mirror each other, from the eyes down to the jaw. Every face is a little asymmetric; the test shows by how much, and where.
Your photo is processed in this browser and never uploaded.
There is no published norm for this exact measurement, so the bands mark where a difference stops being explained by photo noise. They are not attractiveness thresholds: studies link symmetry to attractiveness only weakly, and perfect symmetry isn't a human trait.
| Result | Difference | What it means |
|---|---|---|
| Low deviation | below 2.5% | Within what ordinary landmark and pose noise produces. Close to the most symmetric faces we measure. |
| Moderate | 2.5% to 5% | A measurable difference, usually concentrated in one or two regions. Common, and rarely noticeable in person. |
| Marked | 5% and above | A clear difference between sides, or a photo taken with the head turned. Retake straight-on before reading too much into it. |
A slightly turned head is the main cause of a high reading. A few degrees is enough to make one side look wider.
It uses the same engine as the Face Analyzer, so both give you the same number for the same photo.
Most facial asymmetry is in the bone and is set by adulthood. Some soft-tissue differences can change: a jaw muscle that's bigger on your chewing side, puffiness from sleeping on one side, and uneven brows that grooming can even out. A side part or beard shape can also make one side look fuller. Bone asymmetry from the jaw or teeth is treated by orthodontists and jaw surgeons, not by exercises.

Note: This is a measurement from one photo, not a medical assessment. If one side of your face has changed recently, or you have pain or weakness, see a doctor.
