Front view - Mouth and lips
Lower to upper lip ratio
Lower lip height divided by upper lip height. A somewhat fuller lower lip is the classical preference, so ratios moderately above 1 are ideal.
What counts as ideal
The ideal band is 1.55 to 1.85 for both men and women. A reading anywhere inside the band scores a full 10.
Ideal range
1.55 to 1.85
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 0.65 and 2.66: 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.
Lower to upper lip 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.
