The criteria, one by one

Criteria, measurements and public weights. Here is what each criterion looks at on your face.

Weights read from /api/how-it-works when the page loads.

Harmony

Two measurements. The first says how close the shape of your face is to the average shape of your bracket. The second checks whether your proportions agree with each other. In a study of 1,550 faces from ten countries, moving away from the average shape lowers attractiveness, everywhere.

One caveat, and we publish it: the second measurement is our own definition. No published study validates it yet.

Dimorphism

One measurement: how wide, long and angular the lower half of your face is. For men, the best is to be close to the average of your bracket. For women, fewer masculine traits raise the rating. That is what the same ten-country study finds: masculinity has a null or weak effect in men, while shape femininity counts in women.

Facial Width

Three measurements count, all relative to the width of your face: eye spacing, mouth width, and the ratio between mouth width and nose width. For eye spacing and that ratio, the best is to be close to the average of your bracket. For the mouth, the wider it is, the higher the measurement.

Two more measurements are computed but weigh zero. Nose width, since 12 September 2026: it measured origin more than attractiveness. And the distance between the inner corners of the eyes, which varies more from one population to another than with attractiveness. Counting them would amount to scoring someone's origin.

Eye Area

Five measurements: eye opening, the tilt of the eye corners, eye length, eye spacing relative to eye size, and eye opening relative to the iris.

One caveat: canthal tilt rests on a single primary study, done on female faces. The "3 to 5 degrees" figures you see online come from blogs.

Jawline

Five measurements: jaw width, face width relative to height, chin width, the contour angle and the taper of the lower face. A face that is very wide for its height is judged more dominant, and less attractive (PLOS ONE, 2015). The rating treats it that way.

Vertical Proportions

Four measurements: the distance from the eyes to the mouth, the ratio of the two measurable thirds, the share of the lower third and the height of the philtrum. The top of the forehead is left out, since the mesh has no point on the hairline. The "three equal thirds" are not used: on real faces, they almost never hold.

Mouth & Lips

Two measurements: the ratio between the upper and lower lip, and lip thickness.

Symmetry

One measurement: left-right symmetry, once the pose is straightened. It counts for little in the total, by design. In the study of 1,550 faces, symmetry had no effect on attractiveness (Evolution and Human Behavior, 2023).
