Dimorphism pillar - Facial features

Jaw

Jaw width measured against cheekbone width, combined with chin height measured against face height. Androgen-driven growth widens the jaw at the gonial angles and lengthens the chin, which makes the jaw one of the two strongest hard-tissue sex markers in the skull-trait literature. Higher readings mean a broader jaw and a longer chin.

By RateMyFaceAI. Methodology

What the reading means

Jaw places a face on the same 0 to 10 spectrum as every other signal in this pillar: 0 is the softest, most feminine shape and 10 the strongest, most masculine shape. There is no ideal band and neither end is better than the other. The reading comes from a set of landmarks, so photo angle, expression and lighting all move it.

The pillar index combines all 10 signals, over whichever of them a face carries a reading for. A signal with no reading drops out instead of counting as a neutral 5, and the signals do not all count equally.

Component readings

Jaw width / cheekbone width
Vertical chin height / face height

The report shows each of these beside the signal, so you can see which part of the reading drove it.

How well it separates

Across the 240 profiles with a reading, men average 6.32 and women 4.42. That is a very large separation: 1.95 pooled standard deviations apart, a statistic called Cohen's d. The two groups overlap on every signal here, so a single reading never identifies anyone's sex.

Male mean

6.32 / 10

Female mean

4.42 / 10

Readings run from 2.24 to 8.02, with a median of 5.73.

How much this signal counts toward the index follows the published evidence behind it, not the separation measured here. A photographed celebrity library is not a population sample, so read these figures as a description of this library.
