About this measurement
The angle at the base of the nose between the glabella and the chin. It grades profile convexity: smaller angles mean a more convex profile (forward midface or recessed chin), larger a flatter one; mid-range is preferred.
Ideal range and how it is measuredScoring curve
165.8 deg (8.0/10)
Every value inside the ideal band scores 10 and the penalty accelerates the further a value falls outside it; where the curve runs flat along the bottom, values score 0. The dashed line marks where your value lands.
