Facial convexity
Overall straightness of your profile from forehead to nose base to chin.
Why it matters
A near-straight profile (slightly convex) is typically preferred; strongly convex or concave stands out.
What facial convexity measures
Facial convexity measures the overall straightness of your profile using three points: the glabella (the most forward part of the forehead between the brows), the subnasale (where the base of the nose meets the upper lip) and the pogonion (the most forward point of the chin). The angle formed at the nose base, between a line up to the forehead and a line down to the chin, is the convexity. The nose itself is deliberately excluded, so this is a read on the forehead-to-chin frame.
A larger angle means a straighter profile. A smaller angle means a more convex one, where the chin sits relatively far back behind the forehead and lip region. A profile can also run concave, with the middle of the face set forward relative to the forehead and chin.
Why straightness is conventionally preferred
A near-straight profile, often with a very slight convexity, is the relationship the profile-aesthetics tradition tends to favour, and a strongly convex or clearly concave profile stands out by contrast. Powell & Humphreys 1984 and Arnett & Bergman 1993 use this kind of glabella-to-chin reading as a way to summarise how the upper and lower face sit relative to one another.
These preferences are conventions, not laws, and they have been challenged for leaning on narrow reference populations. Convexity varies meaningfully by ethnicity and by sex, so a number outside the band describes how a profile compares to one reference frame and is not a measure of attractiveness in any absolute sense, nor of personal worth.
The typical range and its caveats
This tool scores a band of roughly 160 to 175 degrees, with a modelled mean near 166 degrees. As the source data notes, profile mesh accuracy is limited, so this angle should be treated as indicative rather than precise.
Because the measure depends on three points spread across the whole face, head tilt has a large effect: rotating the chin up or down shifts the apparent angle. Treat the value as a rough guide and lean on a relaxed, level, side-on photo.
Interpreting your number and what can change
Most of what sets your convexity is the underlying relationship between the upper jaw and the chin, which is fixed bone structure rather than anything grooming, posture or skincare can move. What you can change honestly is the read: a level head, even lighting and a true side-on angle stop the camera from inventing convexity that is not really there.
Where the profile is driven by a set-back chin, filler can add forward projection temporarily, and a genioplasty or orthognathic surgery can correct the underlying jaw relationship permanently. These are stated as factual options only. They are significant medical procedures and any decision belongs with a qualified specialist.

What your reading means
- Typical
- Your profile is pleasingly straight.
- Less common
- Your profile convexity is close to the preferred range.
- Distinctive
- Your profile reads notably convex (chin set back) or concave.
How we measured it
From your side photo, the angle from the forehead through the nose base to the chin.
The evidence
Profile mesh accuracy is limited; treat as indicative.
