Jawline Analyzer
This free jawline analyzer measures two things that together describe how defined a jaw reads in a photo: how much your jaw tapers in from your cheekbones, and how sharply the two sides of your jaw meet at the chin.
About the Jawline Analyzer
Taper is your jaw width divided by your cheekbone width, and the classical reference sits around 0.86, meaning the jaw is normally a little narrower than the cheekbones. Chin angle is the angle formed at your chin point between the left and right jaw contours, referenced against roughly 108 degrees, where a smaller angle reads as a more pointed chin and a larger one as a blunter, squarer chin. Taper contributes 60% of the jawline score and chin angle the remaining 40%. That score is then 15% of your overall Harmony Score, alongside symmetry, proportions, eye spacing, and cheekbones.
Two honest caveats. A dense beard obscures the true jaw contour and will usually read as a softer jawline than you have, so measure clean-shaven or with short stubble for the most accurate result. And chin-up or chin-down camera angles change this measurement more than almost any other on the face, so shoot level with your eyes. The report translates your specific numbers into grooming and collar choices rather than recommending any procedure. Analysis runs entirely in your browser and your photo is never uploaded.
This test is part of Calqora's full Face Analysis tool: the same photo also gives you scores for every other category, so you get the complete picture, not just one number.
How We Calculate Your Score
No black box: your Harmony Score is a weighted composite of five measurable categories, each computed from a 478-point 3D face mesh detected on your device. The feature-by-feature breakdown of your eyes, eyebrows, nose, and lips shown with the report is descriptive detail. It does not feed into the score.
Facial Symmetry
weight 25%
A midline is drawn through your nose bridge and chin, then 9 landmark pairs (eye corners, brow ends, nostrils, mouth corners, jaw contour) are compared across it, both horizontal distance and vertical height.
Facial Thirds & Proportions
weight 25%
Your face is split into vertical thirds (hairline→brow, brow→nose base, nose base→chin) and scored on how evenly they divide (60%), plus your face length ÷ cheekbone width against the classical 1.618 golden-ratio reference (40%).
Eye Spacing & Canthal Tilt
weight 20%
The distance between your inner eye corners is compared to the width of one eye (the classical rule of fifths), and the angle from outer to inner eye corner measures canthal tilt.
Jawline Definition
weight 15%
Jaw width ÷ cheekbone width measures taper (60%), and the angle formed at your chin between the left and right jaw contours measures chin definition (40%).
Cheekbone Prominence
weight 15%
Cheekbone width ÷ jaw width (60%) and cheekbone width ÷ face length (40%) measure how strongly the midface projects relative to the lower face.

Frequently Asked Questions
How does the jawline analyzer measure my jaw?
An on-device AI model maps a 478-point 3D mesh on your photo. From it the tool measures jaw width at the gonial corners, cheekbone width at its widest horizontal point, and the angle formed at your chin between the two jaw contours. Jaw divided by cheekbone width gives the taper ratio, weighted at 60% of the jawline score, with the chin angle making up the other 40%.
What is a good jaw to cheekbone ratio?
The classical reference is about 0.86, a jaw slightly narrower than the cheekbones, which produces the taper most styling advice assumes. Ratios near 1.0 mean jaw and cheekbones are close to equal width, which reads as a square or rectangular lower face. Neither is better. They suit different haircuts, beard shapes, and glasses, which is what the report is actually for.
Can I improve my jawline?
Bone structure does not change with exercise, and chewing devices do not alter the underlying jaw geometry this tool measures. What genuinely changes how defined a jaw looks is body composition, a short boxed beard or defined stubble line, collar and neckline choices, and camera angle. The report gives styling guidance in those terms. It does not recommend cosmetic procedures.
Does facial hair affect the jawline measurement?
Yes, more than anything else. A dense beard hides the actual jaw contour and the landmark detector will trace the hair rather than the bone, which typically produces a lower taper score and a blunter chin angle than your real structure. For the most accurate reading, measure clean-shaven or with short stubble, then use the report to decide what beard shape suits the result.
Is the jawline analysis private?
Yes. The model runs in your browser and your photo is never uploaded, stored, or logged. No account is required, and the shareable result card contains only your scores, never your image.
