Front view - Eyes and brows
Eye separation ratio
Interpupillary distance as a percentage of cheekbone width. It measures whether the eyes sit close together or far apart for the width of the face; mid-range spacing is preferred.
What counts as ideal
The ideal band differs by sex for this measurement: 45.70% to 46.80% for men and 46.50% to 47.50% for women. A reading anywhere inside the band scores a full 10.
Male ideal
45.70% to 46.80%
Female ideal
46.50% to 47.50%
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 40.47% and 51.04%: 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.
Eye separation 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.
