How to Find Your Face Shape From a Photo
By AI Clothes Swapper teamLast updated:
Quick answer: Upload a straight-on selfie to a free face shape detector. It measures your face length against your cheekbone width, then compares your forehead and jaw widths with your cheekbones. Long faces are oblong, wide-jawed short faces are square, a wide forehead over a narrow jaw is heart, and balanced proportions are oval. FaceScore does this in your browser in about 10 seconds, without uploading the photo.

Which measurements decide your face shape?
Three ratios decide it:
| Ratio | What it compares |
|---|---|
| Length to width | Estimated face length ÷ cheekbone width |
| Jaw to cheek | Jaw width ÷ cheekbone width |
| Forehead to cheek | Forehead width ÷ cheekbone width |
What are the exact cut-offs?
FaceScore checks these rules in order and uses the first one that fits:
| Face shape | Rule |
|---|---|
| Oblong | Length is 1.56× the width or more |
| Heart | Forehead is at least 0.08 wider (as a share of cheek width) than the jaw, and the jaw is under 0.80 of cheek width |
| Diamond | Forehead under 0.82 and jaw under 0.78 of cheek width (cheekbones are the widest part) |
| Square | Short face (under 1.40) with jaw 0.86 or more, or any face with jaw 0.88 or more |
| Round | Short face (under 1.40) with a narrower jaw |
| Oval | Everything else: balanced length and a jaw narrower than the cheekbones |
We set these bands from 18 straight-on portraits, where length to width ran from 1.42 to 1.59. The landmark mesh stops at the hairline, so face length is estimated from the brow-to-chin distance.
How to take a photo for a face shape test
- Pull your hair back from your forehead, temples and jaw.
- Hold the camera at eye level, at arm's length or farther.
- Look straight at the lens with a neutral face.
- Use even light; strong shadows hide the jaw line.
If two photos give different shapes, your proportions are probably near a border between two shapes. Pick haircuts that suit both.
Which haircuts suit each face shape?
| Face shape | Aim for | Try |
|---|---|---|
| Oval | Keep the balance | Most cuts; curtain bangs, long layers, a textured bob |
| Round | Add height, keep the sides slim | Volume on top, long layers, side part |
| Square | Soften the jaw | Soft layers around the jaw, side-swept bangs |
| Heart | Add width at the jaw | Chin-length bob, side part, fuller ends |
| Diamond | Add width at forehead and jaw | Fringe, chin-length cuts, tucked-behind-ear styles |
| Oblong | Shorten the face visually | Bangs, width at the sides, avoid extra height |
See the cut on your own face first
Lists help, but a haircut looks different on every face. The $19 FaceScore report makes four AI previews of your own face, including two haircuts chosen for your shape and a pair of glasses, so you can see them before you book.
FAQ
Is a face shape detector accurate? It is consistent: the same photo gives the same shape. It can be wrong when hair covers the jaw or the photo is taken from below.
Can my face shape change? Your bone structure doesn't, but weight changes and hair can change how the outline reads.
Is the test free? Yes. The face shape test, score, symmetry and canthal tilt are free with no sign-up.
