Nasofacial angle
How far your nose projects from the plane of your face.
Why it matters
Nasal projection balances the profile; too much or too little throws off nose-face harmony.
What nasal projection in profile means
The nasofacial angle describes how far the nose stands out from the flat plane of the face. Picture a line running down the front of the face in profile, from the brow region to the chin: the facial plane. Now picture the line of the nasal bridge, from the top of the nose to the tip. The angle between those two lines is the nasofacial angle, and it captures nasal projection.
A larger angle means a nose that juts further forward from the face; a smaller one means a flatter, less projected bridge. Powell & Humphreys (1984), in their framework for the proportions of the aesthetic profile, treated this angle as one of a connected set of profile relationships.
Why projection sits inside a system
Projection rarely reads in isolation. A nose can look strongly projected mainly because the chin behind it is set back, or modest because a strong brow and chin balance it.
That is why this tool, following Powell & Humphreys (1984) and Naini (2011), treats nasal projection as part of a profile system rather than a standalone trait: the same nose reads differently against different foreheads and chins. The convention is that projection in balance with the rest of the profile reads harmonious, while too much or too little stands out.
The typical band and its limits
The band here treats roughly 30 to 40 degrees as balanced, with a modeled average near 34. Below that the nose reads as under-projected for the face; above it, as more projected. This draws on Powell & Humphreys (1984) and Naini (2011).
The honest limit, stated by the tool, is that profile mesh accuracy is limited, so the figure is indicative. Head rotation toward or away from the camera changes apparent projection markedly, so a level, true side-on photo matters more for this metric than for most.
Reading and changing it
Read your value as a ballpark that depends as much on the chin and brow as on the nose itself. A number outside the band often says as much about a set-back chin or a flat brow as it does about the nose.
Projection is set by the nasal bones and cartilage and is fixed structurally. Presentation levers are limited to honest photography (a true profile, a level camera) and, indirectly, to anything that balances the chin and brow around the nose. Non-surgical options for reducing projection are minimal, though building up a weak chin with filler can rebalance the look temporarily. Surgically, rhinoplasty adjusts projection directly and permanently. That is stated as fact, not advice.
Typical range
~30-40°
Angle between the facial plane (glabella to chin) and the nasal dorsum (bridge). Describes how far the nose projects relative to the face. From the profile photo.
What your reading means
- Typical
- Your nose projects in balance with your face.
- Less common
- Your nasal projection is close to the preferred range.
- Distinctive
- Your nose projects more or less than the balanced range.
How we measured it
From your side photo, the angle between the facial plane (forehead to chin) and the nasal bridge.
The evidence
Profile mesh accuracy is limited; treat as indicative.
