Side view - Chin and jaw

Ramus to mandible ratio

The length of the ramus (ear to jaw corner) divided by the jawline (corner to chin). It proportions the vertical and horizontal parts of the jaw; mid-range ratios support a defined jaw corner at a good height.

What counts as ideal

The ideal band is 0.62 to 0.75 for both men and women. A reading anywhere inside the band scores a full 10.

Ideal range

0.62 to 0.75

How it is scored

Everything inside the band scores 10, and the penalty accelerates the further a reading falls outside it rather than dropping off a cliff at the edge. For the male band, the falloff is measured against bounds of 0.41 and 1.14: a reading out at either of those has spent its full allowance and scores about 3. The curve keeps going past them, so an extreme reading still separates from a merely poor one.

Ramus to mandible ratio is one of 67 measurements in the harmony pillar. No single measurement decides a face: each one contributes its own shortfall to a weighted mean, and one hopeless measurement costs a full measurement's worth and never more.
