Side view - Chin and jaw

Mandibular plane angle

The steepness of the jawline from the jaw corner to the chin against the horizontal. Flatter planes read as a strong, horizontal jawline; steep planes as a downward-sloping lower face.

What counts as ideal

The ideal band is 15.0 deg to 22.0 deg for both men and women. A reading anywhere inside the band scores a full 10.

Ideal range

15.0 deg to 22.0 deg

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 -6.0 deg and 32.0 deg: 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.

Mandibular plane angle 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.
