Side Profile Analysis
Upload one true side-on photo. Your profile is traced automatically, eleven soft-tissue points are placed on it, and you get the angles clinicians use to describe a profile: facial convexity, nasolabial, nasofrontal and mentolabial angles, your gonial (jaw) angle, both lips against the E-line and chin projection. Every point is drawn on your photo and can be dragged.

How it is measured
Trace the outline, find the points, measure the angles.
A front-facing face mesh cannot see a 90° profile, so this tool does not use one. An on-device segmentation model separates hair, face skin, neck and background. The front edge of your head is traced row by row, smoothed, and walked from the nose tip: its forward peaks are the brow, nose tip, lips and chin, its valleys the nose root, the point under the nose and the chin fold. The jaw corner comes from where face skin meets the neck. When that corner is hidden by the ear or hair, or a beard or bangs cover the outline, the tool says so and you drag the point into place. The angles use the final points, so you can check each one.
- Facial convexity
- Angle at the point under the nose, between the brow ridge and the chin. Around 165–175° is the common reference.
- Nasolabial angle
- Between the underside of the nose and the upper lip. Around 90–110° is the common reference.
- Nasofrontal angle
- Where the forehead meets the nose. Around 115–135° is the common reference.
- Mentolabial angle
- The fold between lower lip and chin. Around 110–140° is the common reference; lower is a deeper fold.
- Gonial angle
- The jaw corner, between the back edge of the jaw and the lower border. Lower reads sharper and more angular.
- E-line
- Nose tip to chin. Lips usually sit slightly behind it.
Measure it yourself
How to take a good side profile photo
- 1Stand side-on to the camera with the camera at face height, a metre or more away (or zoomed in from further).
- 2Look straight ahead at a point level with your eyes; don't tilt your chin up or down.
- 3Tie hair back so the jaw corner and ear are visible, and use a plain background.
- 4Upload it: the points appear on their own. Drag any point that sits off, for example over a beard or bangs.
Skip the ruler: the free tool above does it from one photo in about 30 seconds ↑

FAQ
What is a good side profile?+
Profiles are described rather than graded: straight, convex (chin set back) or concave (chin forward). The readings show where yours sits against common clinical reference ranges, which vary with sex and ethnicity.
What is the gonial angle?+
The angle at the corner of the jaw. A lower angle reads as a sharper, more defined jaw; a higher one as softer. On soft tissue it is approximate, because the bone corner sits under muscle and skin.
What is the E-line?+
Ricketts' esthetic line, from the nose tip to the chin. It is used to describe how far forward the lips sit.
Are the points placed automatically?+
Yes. The outline is traced on your device and eleven points are placed on it. A beard, bangs, glasses on the nose or a busy background can move a point, so each one can be dragged, and you can switch to placing all of them yourself.
Why is my jaw angle marked as estimated?+
The corner of the jaw is only visible when nothing covers it. Long hair, the ear or a beard often hide it; the tool then guesses its position and asks you to drag it onto the corner of your jaw.
Is my photo uploaded?+
No. Everything runs in your browser.
