Face Shape Detector

Find your face shape from a photo — oval, round, square, heart, oblong, or diamond — plus hairstyle, glasses, and makeup tips that flatter it. It is a best-guess estimate, it is free with no sign-up, and your photo never leaves your phone: it is analyzed entirely in your browser and is never uploaded.

What is the Face Shape Detector?

The Face Shape Detector is a free tool that estimates your face shape from a photo and then suggests hairstyles, glasses, beard styles, and makeup that flatter it. Upload a clear, front-facing picture and it gives you a best-guess shape — oval, round, square, heart, oblong, or diamond — in seconds. The whole thing runs in your browser: your photo is analyzed on your own device and is never uploaded, stored, or seen by anyone. It is meant as a quick, private starting point before a haircut or a frame purchase, not a clinical measurement.

How to use it

Tap Upload a photo and pick a clear, front-facing picture of yourself — neutral expression, even lighting, hair pulled off your face.
The on-device model loads (a short, one-time download that stays on your device) and measures your facial proportions.
Read your best-guess face shape, the measured ratios behind it, and a closeness note (mostly oval, a bit of round).
If it doesn't look right, tap a different shape to override it — the styling tips update instantly.
Scroll the styling guidance for your shape, take what's useful, and go. There's nothing to save, sign into, or clean up.

The method behind it

There is no magic and no black box. The tool works in two transparent layers. First, an on-device machine-learning model — a face-landmark detector running in your browser via WebAssembly and WebGL — locates hundreds of points around your face: the chin, jaw corners, cheekbones, temples, and forehead. Second, from those points it computes a small set of interpretable ratios: face length compared with its widest point, jaw width versus cheekbone width, forehead width, and how angular or pointed the chin is. A simple, rule-based classifier then matches those ratios to the nearest face-shape archetype. Because the rules are explicit, the tool can show you why it guessed what it did — it displays the ratios it measured rather than handing you a verdict you have to take on faith.

The result is an estimate, not a precise instrument. Photo angle, expression, hairline, and lighting all shift the numbers, and most real faces are a blend of two shapes — which is exactly why you can override the guess and pick the one that matches what you see in the mirror.

The six face shapes explained

Oval — Longer than it is wide, with the forehead a touch wider than the jaw and gently rounded edges. Considered balanced because most styles suit it.
Round — Length and width are close to equal, with full cheeks and a soft, rounded jaw.
Square — Length and width are similar with a strong, angular jaw and similar forehead, cheek, and jaw widths.
Heart — A wider forehead and cheekbones that taper to a narrow, pointed chin.
Oblong — Noticeably longer than it is wide, with straight sides and a fairly even width top to bottom.
Diamond — Cheekbones are the widest point, with a narrower forehead and jaw and a pointed chin.

These are reference shapes, not boxes. Many people sit between two of them, and that's normal.

Styling by face shape

The goal of all of these tips is the same: gently balance and harmonize your proportions. Every shape has flattering options — none is better than another. Pick your shape in the tool above to see this guidance highlighted for you, or read all six here.

Oval

Hairstyles: Almost anything works — keep balance by avoiding very heavy fringes that shorten the face.
Glasses & sunglasses: Most frame shapes flatter; try frames as wide as the broadest part of your face.
Beard styles: Light, even stubble or a short beard keeps the natural balance.
Makeup & contouring: Minimal contouring needed — a light cheekbone touch is plenty.

Round

Hairstyles: Height and length add the look of length; side parts and layers slim the face.
Glasses & sunglasses: Angular or rectangular frames add definition and counter the soft curves.
Beard styles: A bit of length at the chin lengthens the face; keep the sides shorter.
Makeup & contouring: Contour below the cheekbones to add structure.

Square

Hairstyles: Soft, rounded styles and layers ease the strong jawline.
Glasses & sunglasses: Round or oval frames soften the angles; avoid sharp boxy frames.
Beard styles: A rounded beard shape softens the jaw; trimmed corners help.
Makeup & contouring: Soften the jaw corners and highlight the center of the face.

Heart

Hairstyles: Volume around the jaw and chin-length styles balance a wider forehead.
Glasses & sunglasses: Bottom-heavy or light rimless frames balance the wider top.
Beard styles: Fuller growth toward the chin adds width to the lower face.
Makeup & contouring: Contour the forehead sides and highlight the chin to balance.

Oblong

Hairstyles: Width and softness at the sides, layers, and fringes shorten the look.
Glasses & sunglasses: Tall or oversized frames break up the length; decorative temples add width.
Beard styles: Fuller sides add width; keep the chin shorter to avoid lengthening.
Makeup & contouring: Highlight across the cheeks to add width.

Diamond

Hairstyles: Volume at the forehead and chin balances the wide cheekbones.
Glasses & sunglasses: Frames with detail or width at the top (cat-eye, oval) flatter.
Beard styles: A fuller jaw and chin widen the lower face to balance the cheekbones.
Makeup & contouring: Soften the cheekbones and add light to the forehead and chin.

Use the on-page guidance for your selected shape, and treat it as general direction, not a rulebook — your own eye and your stylist always win.

Tips for an accurate result

Use a front-facing photo, looking straight at the camera.
Keep a neutral expression (a big smile changes your proportions).
Use even lighting with no harsh side shadows.
Pull hair off your face so your hairline and jaw are visible.
Avoid steep angles, tilts, and heavy filters.

Privacy

This is the part we care most about. Your photo is processed on your device, in your browser, by an on-device model. There is no server step and no backend — so the image is never uploaded, never transmitted to us or any third party, and nothing is stored. We don't keep your photo, your result, or any history. Close the tab and it's gone. We can say this plainly because it is structurally true: there is simply no place for your image to go.

Is it accurate? What to expect

Treat the result as a helpful estimate, not a clinical verdict. Browser-based geometry from a single photo gives a plausible best guess, but faces are blends, and angle, expression, hairline, and lighting all move the numbers. That's why we show the measured ratios and let you override the shape. Use it as a confident starting point for a new haircut or pair of frames — then trust your own eye and, when it matters, a professional.

When this helps (and when it doesn't)

It's useful before a haircut, when choosing glasses or sunglasses, when trying a new beard or makeup look, or just out of curiosity. It is not a medical, dental, orthodontic, or cosmetic-surgery tool, and it does not rate attractiveness or infer age, gender, or any other personal attribute. It estimates geometric face shape and suggests flattering styles — that's the whole job.

Frequently asked questions

Is the face shape detector free?

Yes. It is completely free with no sign-up, no account, and no paywall — just open it, upload a photo, and get your result.

Do you upload or store my photo?

No. Your photo is analyzed entirely in your browser using on-device machine learning. There is no backend, so the image is never uploaded, never sent to us or anyone, and nothing is stored. When you close the tab, it is gone.

How accurate is the face shape detector?

It gives a best-guess estimate based on your facial proportions, not a clinical measurement. Real faces are usually a blend of shapes, and the result varies with photo angle, expression, hairline, and lighting. We show the proportions we measured so you can see how the guess was made, and you can override it and pick the shape yourself.

How do I measure my face shape?

The tool measures it for you from a photo: it finds facial landmarks, then computes ratios such as face length versus width, jaw width versus cheekbone width, and forehead width, and matches the closest archetype. To measure it yourself, compare your face length to its widest point and check whether your jaw, cheekbones, or forehead is widest.

What are the main face shapes?

The six common shapes are oval, round, square, heart, oblong, and diamond. They are defined by proportions — for example, oval is longer than it is wide with gentle curves, square has a strong angular jaw with similar forehead, cheek, and jaw widths, and heart has a wider forehead with a narrow, pointed chin.

Why does it ask for a clear, front-facing photo?

Angle, hair, and lighting all change the proportions the tool measures. A clear, front-facing photo with a neutral expression and hair pulled off your face gives the most reliable estimate.

Does it work on my phone?

Yes — it is mobile-first. The on-device model loads only when you choose to analyze a photo, so the page stays fast, and everything runs locally on your device.

Does it judge attractiveness?

No. It only estimates geometric face shape and suggests flattering styles. There is no beauty score, no attractiveness rating, and no age, gender, or other inference — and every face shape has great styling options.
