Nose measurement

Nasal Tip Angle

Angle at the nose tip between the nasal dorsum (towards nasion) and the columella. It reflects tip definition and rotation; slightly larger values are typical in women.

The points and construction lines on a reference profile, with the Frankfort horizontal level.

How it is measured

∠ N–Prn–Cm

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.
Cm Columella point — The point just behind the tip where the rounded tip turns into the straighter underside of the nose (the columella).

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.

Men
Tier	Range	Rating
T1 Ideal	112–125°	9.5–10
T2 Near ideal	109–112° or 125–128°	7.2–9.5
T3 Mild deviation	105–109° or 128–132°	5.2–7.2
T4 Moderate deviation	100–105° or 132–137°	3.4–5.2
T5 Significant deviation	97–100° or 137–140°	−5 to 3.4
T6 Severe deviation	< 97° or > 140°	−10 to −5

Women
Tier	Range	Rating
T1 Ideal	118–131°	9.5–10
T2 Near ideal	115–118° or 131–134°	7.2–9.5

T4 Moderate deviation	106–111° or 138–143°	3.4–5.2
