Total facial convexity (with nose)
Profile convexity including the nose (forehead to nose tip to chin).
Why it matters
Adds the nose into the profile read — useful for seeing whether the nose drives an overall convex look.
What this measure adds over plain convexity
Total facial convexity uses the same idea as facial convexity but swaps the middle point: instead of the nose base, it runs the angle through the nose tip, measuring glabella to nose tip to pogonion (the chin). In other words, it folds the nose into the read of the profile, so it answers a slightly different question, how convex the face looks once the nose is included.
Because the nose tip stands forward of the nose base, this angle is naturally smaller (more convex) than the bare forehead-to-chin reading. Comparing the two is informative: a large difference between them is a sign that the nose itself, rather than the jaw relationship, is what makes the profile look convex.
Why it matters perceptually
The eye does not separate the nose from the rest of the profile when forming an impression, so a measure that includes the nose tip can track what an onlooker actually sees more closely than one that leaves the nose out. Naini 2011 and Powell & Humphreys 1984 treat overall profile convexity as one of the summary descriptors of a balanced side view.
This remains an aesthetic convention, and the underlying preferences are debated and vary by ethnicity and sex. A value outside the preferred band describes a profile shape and the contribution of the nose to it; it is not a ranking of a face and has no bearing on a person's worth.
The typical range and its caveats
This tool scores a band of roughly 135 to 150 degrees, with a modelled mean near 143 degrees, lower than the plain facial-convexity band precisely because the forward nose tip is now part of the line. As with all profile metrics here, mesh accuracy is limited, so the figure is indicative.
Head tilt and the angle of the camera move this measure even more than the nose-base version, because the nose tip is the most forward and most movement-sensitive of the three points. Use a level, relaxed, side-on photo and confirm with a second image.
Interpreting your number and what can change
Read this alongside plain facial convexity. If the two are close, the profile shape comes mostly from the jaw-and-forehead frame; if total convexity is much smaller, the nose is doing the work. Either way, the bone-and-cartilage structure is fixed, and the honest levers are photographic, a true side angle, good posture and even lighting.
Where someone wishes to change the balance, rhinoplasty alters the nose and a genioplasty alters the chin, and the two are sometimes considered together because each shifts this angle. They are noted here only as factual options, not recommendations, and are decisions for a qualified surgeon.
Typical range
~135-150°
Glabella to nose tip to pogonion — overall profile convexity including the nose. Distinguishes a straight from a convex (or concave) profile. From the profile photo.
What your reading means
- Typical
- Your overall profile (with nose) is well balanced.
- Less common
- Your total convexity is close to the preferred range.
- Distinctive
- Including the nose, your profile reads notably convex or concave.
How we measured it
From your side photo, the angle from the forehead through the nose tip to the chin.
The evidence
Profile mesh accuracy is limited; treat as indicative.
