Front view - Mouth and lips

Chin to philtrum ratio

Chin height (below the lower lip) divided by philtrum height (nose base to upper lip). It balances the two halves of the lower face; mid-range ratios avoid the look of a long philtrum or an oversized chin.

What counts as ideal

The ideal band is 2.15 to 2.45 for both men and women. A reading anywhere inside the band scores a full 10.

Ideal range

2.15 to 2.45

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 1.65 and 2.95: 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.

Chin to philtrum 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.
