Face Shape Detector: Find Your Face Shape From a Photo
Upload a front-facing photo. Your browser measures your face’s proportions in about a second, then shows which of five shapes (oval, round, square, heart or oblong) it is closest to. Your photo is not uploaded.

How this face shape detector works
Google’s MediaPipe Face Landmarker finds 478 points on your face inside your browser. From them we measure the width of your forehead, cheekbones, jaw and chin and the length of your face, all relative to your cheekbone width. A small statistical model, trained on 2,497 labelled photos, then picks the shape those proportions most resemble.
2. Your browser measures it
About a second, with no upload and no account. The lines on your photo show what was measured.
3. See the closest shapes
You get a ranked list of all five shapes, not a single verdict, plus the measured ratios behind it.
How accurate is it?
We tested it on 300 photos the model had never seen. The shape it ranked first matched the dataset’s label 50% of the time, and the label was among its top two 72% of the time. Guessing would get 20% and 40%.
That is a ceiling set by the question as much as by the maths: people agree on face shape only loosely, and the dataset’s labels are human judgements of celebrity photos. So the result is “closest to”, and when no shape clears 50% you see “between” two shapes instead of a forced answer.
The five face shapes
Oval
Balanced proportions: a little longer than wide, a forehead slightly wider than the jaw, and a softly rounded chin.
Round
Length and width close to equal, full cheeks, and a soft jaw and chin without strong angles.
Square
A forehead, cheekbones and jaw of similar width, with a strong, angular jawline.
Heart
A wider forehead and cheekbones that taper to a narrower chin, often more pointed.
Oblong
Noticeably longer than wide, with forehead, cheeks and jaw of similar width.
Tips for a fair reading
Face the camera
A turned head changes every width. Look straight at the lens with your chin level.
Hair back
Hair over the forehead or jaw hides the outline the model follows. Tie it back or tuck it behind your ears.
Neutral expression
A big smile or open mouth reshapes the lower face. Relax your jaw.
Camera at eye level
Hold it at arm’s length and use the 2x lens: close wide-angle selfies stretch the middle of the face.
Soft, even light
Strong shadows along the jaw make the outline harder to find.
No filters
Beauty filters reshape the jaw and cheeks, so you would be measuring the filter.
What a face shape result cannot tell you
A face shape is a rough description of an outline, not a rule. Beards, hair, makeup contouring, weight changes and age all alter the outline, and many faces sit between two shapes. A stylist or optician will use it as one starting point alongside your hair, features and taste. It says nothing about attractiveness, and it is not medical or cosmetic advice.

Common questions
FAQ
Upload a front-facing photo above. The detector measures your forehead, cheekbone, jaw and chin widths against your face length and shows the shape your proportions are closest to, ranked against the other four.
Pull your hair back, look straight at a mirror or camera, and compare four widths — forehead, cheekbones, jaw and chin — plus the length from forehead to chin. A face that is clearly longer than wide is oblong; roughly equal length and width with a soft jaw is round, with a strong jaw is square; a wider forehead tapering to the chin is heart; balanced and slightly longer than wide is oval.
It is a good guide, not a verdict. On photos it had never seen, the top-ranked shape matched the dataset label 50% of the time and was in the top two 72% of the time, against 20% and 40% for guessing. People themselves disagree about face shape, so treat it as “closest to”.
No. The detector runs in your browser and the photo is not uploaded for it. The only thing downloaded is the face model, about 7 MB, once.
Yes. It measures the same proportions on every face and does not use gender. A beard can hide the jaw outline, so for the fairest reading use a photo where your jaw is visible.
Yes. Weight changes, age, a beard or a different hairstyle can all change how an outline reads, and a photo taken at a different angle can too. That is why the result is a ranking, and why retaking the photo is worth trying.
Many faces do. When no shape clears 50% you will see “between” the top two. That is an honest answer: your proportions sit between those shapes.
None. Face shape is a description, not a ranking of attractiveness, and every shape suits many looks.
No. This tool measures outline proportions only. The AI face rater judges how well a photo presents you — light, angle, expression and styling — and gives a retake plan.
