Side profile analyzer. See where your chin sits.

Orthodontists judge a side profile by how the forehead, the base of the nose and the chin line up, not by one feature (Arnett et al. 1999; Ricketts 1968). The line runs glabella → subnasale → pogonion. This tool reads that one angle. The jaw corner is left out because in a phone photo it usually sits under hair, the ear or soft tissue. The angle under the chin is left out because in one photo it mostly shows how you held your head.

Here is the one measurement this tool reads, and the figure the study gives.

Any dot can be dragged, and a dot a few pixels off moves the angle. We measured it on the example man's photo (960 × 1200 px) by moving each point in every direction. The base of the nose moves the angle the most.

That is why the answer is a type in words, never a decimal. The types are wide on purpose: chin sits back below 160°, chin slightly back from 160° to 176°, chin in line from 176° to 182°, chin forward above 182°. These bands are ours, set wider than the published norm so a small slip is less likely to change the answer. When your angle lands within 3° of an edge (1.5° on the side of the narrow in-line type), the answer says it sits between the two types and gives the tips for both. The published typical range, 164° to 172° (Legan & Burstone 1980), lies inside chin slightly back, which is why the page says most adults sit there. On your own photo the page finds you against the background (MediaPipe's selfie model, run in your browser) and follows the edge of your face: the forehead dot goes on the most forward point of your brow above the nose, the nose-base dot on the corner where your nose meets your lip, and the chin dot on the most forward point of your chin. If it can't find a side profile, you tap the three points yourself.

Your forehead, nose and chin are set by bone and cartilage, so exercises don't move them. Two everyday changes do affect how your profile looks from the side:

If you hold your phone in your hand at arm's length (30 cm) and twist your neck sideways to take a profile photo, two errors ruin the measurement before you even start: the 24 mm wide-angle lens makes your nose look bigger, while twisting your neck pulls your chin out of its natural place. Follow these four rules. CEVO's scan reads your iris size to tell how close the camera was, and asks for a retake if the photo was taken too close.
