Face shape detector
Updated October 24, 2026 · Free, no sign-up, no upload
Find out whether your face is oval, round, square, oblong, heart or diamond from one front-facing photo, with glasses and hairstyle ideas for your shape. The detection runs on your device; your photo is never uploaded.
How to find your face shape
- Take or choose a photo facing the camera straight on, at eye level, with your hair pulled back.
- Pick it above. The face model loads once (about 7 MB), then finds your face in a second or two.
- Read your result: the closest shape, how close the others are, and the four measurements drawn on your photo.
The six face shapes
Oval
Longer than it is wide, with the jaw a little narrower than the forehead and soft, rounded lines. The most balanced shape.
Glasses: Almost any frame suits you; wayfarers, aviators and square frames that are as wide as your face look best.
Hair: Most cuts work. Keep some face showing; very heavy fringes hide your balance.
Round
About as long as it is wide, with full cheeks and a soft, rounded jaw and chin.
Glasses: Angular and rectangular frames add definition; avoid small round ones.
Hair: Height on top, side parts and long layers that fall below the chin make the face look longer.
Square
A wide, strong jaw about as wide as the forehead and cheekbones, with angular lines.
Glasses: Round and oval frames soften the angles; thin metal or rimless frames keep it light.
Hair: Soft layers, side-swept fringes and texture around the jaw; avoid blunt cuts that end at the jawline.
Oblong
Clearly longer than it is wide, with forehead, cheekbones and jaw of similar width.
Glasses: Tall, oversized or decorated frames break up the length.
Hair: Volume at the sides, fringes and waves; avoid a lot of height on top.
Heart
A wider forehead and cheekbones narrowing to a slim, often pointed chin.
Glasses: Frames wider at the bottom, aviators and light rimless styles balance the forehead.
Hair: Side-swept fringes and chin-length cuts or bobs that add width at the jaw.
Diamond
Cheekbones are the widest part, with a narrower forehead and jaw.
Glasses: Cat-eye, oval and browline frames, which are wider at the top.
Hair: Fringes and fuller styles at the forehead and chin; slick-backed styles show off the cheekbones.
How it measures your face
The detector uses MediaPipe Face Landmarker, an open-source model from Google that places 478 points on a face. From those it measures four things: face length, and the width of your forehead, cheekbones and jaw. Each shape has typical proportions (a round face is about as long as it is wide; a heart face has a jaw much narrower than its forehead), and your result is the shape your proportions are closest to.
Questions
How does the face shape detector work?
It finds 478 points on your face, then measures your face length, forehead, cheekbones and jaw, and compares those proportions with each face shape. You get the closest shape and how close the others are.
Is my photo uploaded?
No. The face model runs in your browser on your own device: your photo is never sent to our server or anyone else's, and it is gone when you close the page.
How accurate is it?
It is a good starting point, not a verdict: hair covering the forehead, a tilted head, a wide-angle selfie or strong shadows all change the proportions. If two shapes score close, you likely sit between them, which is common.
How should I take the photo?
Face the camera straight on, at eye level, about an arm's length away, in even light. Pull hair off your forehead and keep a neutral expression.
What are the main face shapes?
Oval, round, square, oblong (long), heart and diamond. Some guides add triangle and rectangle; most faces are a mix of two shapes.
