The science
The two measurements that describe a profile
01
Orthodontic profile assessment leans on a handful of references, and this tool measures the two most useful. The facial convexity angle — brow ridge to the base of the nose to the chin — describes how the jaw sits relative to the upper face: roughly 165–177° reads straight ("orthognathic"), smaller angles read convex (chin relatively back), larger read concave (chin relatively forward). The Ricketts E-line runs from nose tip to chin: adult lips typically rest slightly behind it, and lip position against it is the standard quick read of profile balance.
02
You place the five points yourself, because landmark models are trained on frontal faces — and manual placement adds a couple degrees of noise, so treat the angle as a range. More important context: attractive profiles span the entire straight-to-convex spectrum, and profile geometry is skeletal — no exercise changes it. Real changes in this category are orthodontic and surgical territory, which is exactly why honest measurement beats forum speculation.
Reading your convexity result
A straight (orthognathic) profile — roughly 165–177° — means your upper face, midface, and chin stack in a near-line: the configuration orthodontics treats as the reference, though not a requirement for an attractive profile. A convex profile (smaller angle) means the chin sits relatively behind the forehead line; mild convexity is extremely common and often reads soft or youthful. A concave-leaning profile (larger angle) means a relatively forward lower jaw — the "strong chin" configuration that fashion periodically celebrates.
The E-line adds the lip layer: lips well behind the line pair with convex profiles and prominent noses; lips at or ahead of the line pair with forward jaws or fuller lips. Orthodontists read these two measures together before treatment because braces and jaw surgery literally move them — which is also the honest disclosure: if your measurements sit far outside the typical bands and it bothers you, the interventions that change profile geometry are orthodontic and surgical, not topical.
Taking a profile photo that measures true
Stand side-on to the camera at eye level, look at the horizon (not down at a phone — neck flexion changes the chin position), relax your lips and jaw, and pull hair behind the ear so the brow ridge and forehead slope are visible. Have someone else shoot from 1.5–2 meters: a selfie-arm profile is both rotated and lens-distorted, and can move the convexity angle by more than the measurement bands are wide.
FAQ
Common questions
What is a good side profile?+
There is no single good one — convexity angles from roughly 165–177° all read as balanced, and attractive faces exist across the range. The measurement describes your geometry; it does not grade it.
What is the E-line?+
Ricketts’ esthetic line: nose tip to chin. Orthodontists use lip position relative to it as a quick profile reference — adult lips typically sit a few millimeters behind it, further behind in profiles with prominent noses or chins.
Can mewing change my side profile?+
Not in adults, per the available evidence. Adult facial bone does not remodel from tongue posture. Genuine changes to profile geometry come from orthodontics or surgery — everything else is lighting and posture.
What is a recessed chin and do I have one?+
A chin that sits notably behind the E-line and pushes convexity under ~160°. Mild versions are common and purely cosmetic; pronounced versions sometimes pair with bite issues, which is an orthodontist conversation rather than a skincare one.
Does mewing improve the side profile?+
Not in adults — facial bone does not remodel from tongue posture, and the viral before/afters are posture, lighting, weight change, and growth in teenagers. Posture does genuinely change how a profile photographs, which is the honest kernel inside the myth.
Which profile is most attractive?+
Preference studies find high ratings across the straight-to-mildly-convex range, with cultural variation. There is no single winner — which is exactly why this tool reports measurements and typical bands instead of a verdict.
