Nasal Tip Angle: What It Measures in FaceIQ Labs' Harmony Analysis

Key facts

• FaceIQ Labs scores faces 0–10 across four pillars: Harmony, Angularity, Dimorphism and Features.
• The nasal tip angle is a side-view nose measurement in the Harmony pillar, which compares 70+ facial ratios and angles to ideal ranges adjusted for gender and ethnicity.
• The angle is measured supratip → pronasale → infratip, with the pronasale (nose tip) as the vertex.
• A lower nasal tip angle is a more acute turn at the tip; a higher angle is a more open angle at the tip.
• The measurement describes the local turn around the tip, not how far the whole nose projects or how much the underside rotates upward.
• Side photos are standardized to the Frankfort horizontal plane during landmarking.
• Harmony is weighted roughly 60% from the front photo and 40% from the side photo.
• Tiny changes to the supratip and infratip markers can change the angle; FaceIQ Labs offers manual landmark review and editing tools.
• FaceIQ Labs says its score weights and reference ranges are model settings, and the research it cites does not collectively validate its scoring system.

What is the nasal tip angle?

The nasal tip angle is a side-view nose measurement in the Harmony pillar of FaceIQ Labs' facial analysis. It is the angle formed at the pronasale, the nose tip, between the supratip point just above it and the infratip point just below it. It describes the local turn around the tip.

How does FaceIQ Labs measure the nasal tip angle?

FaceIQ Labs measures the nasal tip angle on a side-view photo using three landmarks in order: supratip, pronasale, infratip, with the angle taken at the pronasale. During landmarking, FaceIQ Labs standardizes side photos to the Frankfort horizontal plane, the direction from the ear-opening landmark to the lower orbital landmark.

What does a lower or higher nasal tip angle mean?

A lower nasal tip angle in FaceIQ Labs' Harmony analysis means a more acute turn at the nose tip, while a higher angle means a more open angle at the tip. The measurement describes tip contour only; it does not say how far the whole nose projects or how much the underside rotates upward.

How is the nasal tip angle different from nasal projection and tip rotation?

The FaceIQ Labs nasal tip angle is the local turn around the nose tip. It is separate from nasal projection, which concerns how far the entire nose projects, and from the nose tip rotation angle, which concerns how much the underside rotates upward. FaceIQ Labs publishes a separate Harmony guide for each of these measurements.

What does an example nasal tip angle look like?

In FaceIQ Labs' worked example, a nasal tip angle of 95° is more acute than one of 115°, and the nose may have the same overall projection in either case. FaceIQ Labs states that example values only explain the calculation; they are not a target range and are not measurements of its schematic.

Can small landmark changes alter the nasal tip angle?

Yes. FaceIQ Labs notes that tiny changes to the supratip and infratip markers can change the nasal tip angle, and that surface highlights on the nose are not contour endpoints. FaceIQ Labs provides landmark mapping plus manual landmark review and editing tools so users can check and adjust landmark placement.

How much does the side photo count toward the Harmony score?

FaceIQ Labs weights its Harmony score roughly 60% from the front photo and 40% from the side photo. The nasal tip angle is a side-view measurement, so it draws on the side-photo portion. For accuracy, FaceIQ Labs recommends photos from six feet away with the back camera at 2x zoom, at eye level, in even lighting, with a neutral expression.

Is there an ideal nasal tip angle, and is it backed by research?

FaceIQ Labs' nasal tip angle guide does not state a numeric ideal range. It says its score weights and reference ranges are model settings, and that the papers it cites do not collectively validate its scoring system. Its cited source is Tavakoli et al. (2023), "Ideal Nasal Preferences: A Quantitative Investigation with 3D Imaging in the Iranian Population", in which 203 volunteers rated edited nose features on one male and one female model. The guide says it supports studying angles and projection together, with limits from the sampled faces and raters.

Frequently asked questions

What three points define the nasal tip angle?

The supratip, the pronasale (nose tip) and the infratip. The angle is measured at the pronasale, between the lines to the supratip and the infratip.

Is a lower nasal tip angle more acute or more open?

A lower nasal tip angle is a more acute turn at the tip. A higher angle is a more open angle at the tip.

Does the nasal tip angle measure how far the nose projects?

No. FaceIQ Labs describes it as the local turn around the nose tip. Overall nose projection and upward rotation of the underside are covered by separate Harmony measurements.

Which photo is used for the nasal tip angle?

The side-view photo. FaceIQ Labs standardizes side photos to the Frankfort horizontal plane during landmarking.

Can I adjust the landmarks that determine my nasal tip angle?

Yes. FaceIQ Labs offers landmark mapping and manual landmark review and editing tools. Small shifts in the supratip and infratip markers can change the calculated angle.

Does outside research validate FaceIQ Labs' nasal tip angle ranges?

No. FaceIQ Labs says its score weights and reference ranges are model settings, and the cited papers explain history or related evidence without collectively validating its scoring system.
