FORMA FEATURE / NOSETip rotation: measurements, ratios, and research
Tip rotation contributes to the orientation of the nasal base. The nasolabial angle also depends on the upper lip, so it is not a pure rotation measurement.
How tip rotation is measured
Measure the angle between the columellar tangent and the upper-lip tangent at their junction. Keep the lip relaxed and note the exact method.
Ratios, ranges & competing claims
95.96° — Another survey’s male mean
A separate study reported a male mean of 95.96° with a standard deviation of 2.57°.
Study: The mean and SD summarize that sample; they are not a safe surgical range or an individualized target. Defining the ideal nasolabial angle
95° — A Japanese sample’s preference
The Japanese nasal-angle study favored 95° in male profiles.
Study: Agreement near the mid-90s across these studies is useful context, but upper-lip inclination and facial background still change the appearance. Ideal Nasal Angle Preferences Among Japanese People
Practical takeaway
The mid-90s are a useful male starting point.
Several sampled preferences cluster near that nasolabial angle. Judge the tip’s orientation together with visible nostril and columellar show.
What changes the answer
The angle includes upper-lip slope. Two identical tip positions can measure differently when the lip inclines differently, and the same angle can show different amounts of nostril.
