How it is measured

∠ between G→Pog and N→Prn

  • G Glabella — The most forward point of the forehead, on the midline between the eyebrows.
  • Pog Pogonion — The most forward point of the chin.
  • N Nasion — The deepest point of the dip between the forehead and the bridge of the nose.
  • Prn Pronasale (nose tip) — The most forward point of the nasal tip.

Ideal range and tiers

Each value falls into a tier (T1 = ideal). Comfortably inside T1 the rating is 10, easing to 9.5 at the edges of the ideal range; beyond it the rating falls with the deviation — fastest in the first tiers outside the ideal — down to −10 (below 0 where the original tier sheet takes points away) at the far end of the worst tier.
