What this face shape detector does
A face shape detector measures the proportions of your face and matches them to one of seven shapes: oval, round, square, oblong, heart, diamond or triangle. Fitcut's runs in your browser, so your photo never leaves your phone. It gives your shape as a mix (for example 62% oval and 25% oblong), the six measurements behind it, and three haircuts from the catalog that fit those proportions. It is free and needs no account.
The shape is a starting point, not the answer. Your hair texture, thickness and hairline decide what a cut can physically do, so the full analysis ranks every cut for your hair as well as your face. See how that works in our AI haircut recommender.
How do I know my face shape?
Compare your face's length with its width, then compare your forehead, cheekbones and jaw: which is widest, and how angular is the jaw corner? Those few proportions decide the shape. You can measure them three ways: with this detector, with a soft tape measure and a mirror, or by tracing your outline on a mirror. They differ in how much you have to judge by eye.
| Method | What you need | What you judge by eye | Result |
|---|---|---|---|
| This detector | A straight-on photo, hair pulled back | Nothing: the outline is found and measured, with your iris as the ruler | A mix of the seven shapes, six measurements and a confidence level |
| Tape measure | A soft tape measure, a mirror, about 5 minutes | Where each width starts and ends, and how angular the jaw corner is | Four numbers and two ratios to compare with the shape table |
| Mirror tracing | A mirror and a washable marker or lipstick | The whole outline and which shape it looks like | One label, often unreliable: visual calls agree poorly with measurements |
Measure your face shape with a tape measure
- Pull your hair back and face a mirror straight on, chin level.
- Face length: from the middle of your hairline to the bottom of your chin.
- Forehead width: across the forehead, about halfway between your brows and hairline.
- Cheekbone width: across the widest point of your cheekbones, just below the outer corners of your eyes.
- Jaw width: from one jaw corner to the other, below the earlobes.
- Divide face length by cheekbone width, and forehead width by jaw width. Note which of the three widths is largest.
Then compare your two ratios with the table of the seven face shapes further down this page. If you land between two shapes, the "what separates them" list below names the one thing to check.
Measured, not guessed.
Step 1
Map
A face model running in your browser finds your face and checks the photo: one face, straight on, neutral expression, good light, hair back.
Step 2
Measure
Your iris (about 11.7 mm across in adults) is the ruler. We level the head, correct for close-up selfie distortion, then measure widths, length and the jaw corner.
Step 3
Compare
The proportions become a face-shape mix, plus three cuts from the catalog you picked that suit those proportions.
Six measurements, one ruler
- Face length
- From the bridge of the nose to the bottom of the chin.
- Cheekbone width
- Across the widest part of the face at the cheekbones.
- Forehead width
- Across the forehead, about a third of the way up from the brows.
- Jaw width
- Between the corners of the jaw.
- Jaw corner
- How curved or angular the jaw corner is, from 0 (curved) to 1 (angular).
- Forehead height
- Hairline to brow line as a share of the full face, when your hairline is visible.
Face-shape labels are fuzzy. We score on measurements.
The seven shapes are a stylists' convention, not a validated classification. Charts draw the lines in different places, and judging by eye is unreliable: in one study, visual face-type calls agreed with caliper measurements at a kappa of just 0.19.
The best published face-shape classifier reached about 85% accuracy on noisy photos. So we don't hand you one label. We show your shape as a mix, like 62% oval and 25% oblong, and our scorer never uses the label at all.
Proportions are also only part of the story. Your texture, density and hairline decide what a cut can physically do, so they carry more weight than face geometry.
The seven face shapes, side by side
The proportions each shape is defined by, as our shape guides use them. A length ÷ width of 1.0 means as long as wide.
| Shape | Length ÷ width | Widest point | Forehead ÷ jaw | Also look at |
|---|---|---|---|---|
| Oval | about 1.3 to 1.45 | the cheekbones, by a little | about 1.0 to 1.15, forehead slightly wider | soft to moderate |
| Round | about 1.0 to 1.2 | the cheeks | close to 1.0 | soft and curved (low angularity) |
| Square | about 1.0 to 1.25 | none; widths are even | close to 1.0 | sharp and angular (high angularity) |
| Oblong | about 1.5 or more | none; widths are even | close to 1.0 | moderate |
| Heart | about 1.25 to 1.45 | the forehead and temples | about 1.15 or more (forehead 15%+ wider) | soft, tapering to the chin |
| Diamond | about 1.35 to 1.5 | the cheekbones, by a lot | close to 1.0; both narrow | Cheekbone prominence about 1.2 or more |
| Triangle | about 1.2 to 1.4 | the jaw | about 0.9 or less (jaw wider) | often angular |
Between two shapes? What separates them
Most faces sit between two shapes. When the detector gives you a split result, this is the one thing to check for each pair.
- Oval or Oblong
- Length ÷ width past about 1.5, with even widths all the way down, reads oblong.
- Oval or Round
- Below about 1.2, with full cheeks and a soft jaw, it starts to read round.
- Oval or Heart
- A forehead 15% or more wider than the jaw, tapering to a finer chin, reads heart; an oval's forehead is only slightly wider.
- Round or Square
- Same proportions; the jaw corner decides. A sharp, angular jaw reads square.
- Square or Oblong
- Both have even widths, but an oblong face is clearly longer (past about 1.5).
- Heart or Diamond
- In a heart the forehead is widest; in a diamond the cheekbones are, and the forehead is narrower.
- Heart or Triangle
- Opposites: a triangle face has the jaw wider than the forehead.
- Diamond or Oval
- Both are widest at the cheeks; in a diamond the forehead and jaw fall away much more sharply.
- Triangle or Square
- A square face keeps forehead and jaw about even; in a triangle the jaw clearly wins.
- Triangle or Round
- A round face is widest at the cheeks with a soft jaw.
Your photo never leaves your phone
The detector uses an open-source face model that runs inside your browser. Your photo is measured in memory on your device and discarded when you leave the page. We don't upload it, store it or see it, and there's no account or email gate. The only download is the model itself, once, from Google's model server.

Each guide ranks the cuts our engine scores highest for that shape, says why each works and when it does not, and gives guard numbers and upkeep.
