Side view - Lips
Holdaway H line
Position of the lower lip against Holdaway's H-line from the upper lip to the chin, in millimeters. A lower lip close to this line keeps the lips and chin in one harmonious plane.
What counts as ideal
The ideal band is -0.2 mm to 1.2 mm for both men and women. A reading anywhere inside the band scores a full 10.
Ideal range
-0.2 mm to 1.2 mm
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 -2.7 mm and 4.0 mm: 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.
Holdaway H line 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.
