Side view - Forehead and brow

Upper forehead slope

The bend between the mid-forehead and the hairline as seen from the brow. A perfectly straight forehead profile reads 0 degrees; larger values mean a more rounded or angled forehead.

What counts as ideal

The ideal band differs by sex for this measurement: 0.0 deg to 2.0 deg for men and 6.8 deg to 9.0 deg for women. A reading anywhere inside the band scores a full 10.

Male ideal

0.0 deg to 2.0 deg

Female ideal

6.8 deg to 9.0 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 10.9 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.

Upper forehead slope 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.
