Face Shape Detector
Find your face shape from a single photo — measured on 478 facial landmarks, in your browser. Your photo is never uploaded, and no account is needed.
You get your shape and the three ratios we used to decide it. Free, unlimited.

Read the formula
Four experimental geometry components. Each is clamped to 0–1; these references are product choices, not population percentiles.
We do not measure objective beauty, skin quality, age, color season or anatomical hairline thirds. Contour angles are not bone angles. Photo perspective and model error affect measurements.

Face shape is a descriptive label, not a score. Nothing is better or worse about any of the seven shapes — they simply call for different hairstyles, frame shapes and necklines.
The three ratios behind your label
Every face-shape label comes down to three measurements. These are yours:
| What we measure | Your value | Reference | Direction |
|---|---|---|---|
| Face length vs width | — | varies by shape reference | compact ← → elongated |
| Jaw vs cheekbone | — | jaw narrower than cheekbones | narrower jaw ← → wider jaw |
| Forehead vs cheekbone | — | depends on shape | narrower forehead ← → wider forehead |
The reference positions above are our product settings, chosen to produce a consistent label. They are not a classification standard, and other tools will draw the boundaries differently.
The seven face shapes
| Face shape | Defining ratios | What it usually means for styling |
|---|---|---|
| Oval | length ≈1.5× width, jaw narrower than cheekbones | Most styles work; balance is already there |
| Round | length ≈ width, soft jaw angle | Add vertical line — height at the crown, angular frames |
| Square | length ≈ width, strong jaw angle | Soften with volume on top, rounded frames |
| Heart | forehead wider than jaw, pointed chin | Add width at the jaw line, avoid heavy fringes |
| Diamond | cheekbones widest, narrow forehead and jaw | Soften the cheekbone line, add width at forehead and jaw |
| Oblong | length > 1.6× width | Add horizontal line — fringe, wider frames |
| Triangle | jaw wider than forehead | Add width up top, keep the jaw line clean |
These descriptions are a styling guide. The detector uses the three reference ratios published on our method page, not jaw angle or a labelled reference set. Treat the label as a starting point, not a verdict.
How we decide yours
We locate 478 landmarks, measure the three ratios above, and rank the distance to each shape's reference point. The full report shows the closest match and an alternative. These are reference matches, not probabilities or biological categories.
The full landmark list and tolerances are published. Read the full method →
Why your photo changes your result
This is the most useful thing on this page. Face shape is one of the measurements a camera affects most:
- Lens distance. A phone held 30 cm from your face makes the nose and the centre of the face larger and the jaw narrower. Step back and use a longer focal length and the same face measures differently.
- Head angle. Tilting the chin down shortens the lower third; lifting it lengthens the face.
- Head rotation. A head turned even slightly makes one cheekbone read wider than the other — often enough to push the label toward Diamond.
- Expression. A relaxed jaw measures wider than a clenched one. A smile widens the mouth and can move the jaw-to-cheekbone ratio into a different band.
- Lighting and hair. Hair covering the temples reduces the measured forehead width. Hard side light can make one half of the face read wider than the other.
This is why we show you the three ratios and not just the label. If your result is a close call between two shapes, changing how the photo was taken is more likely to change your label than anything else you could do. Same face, different camera setup, different answer.
What this label doesn't tell you
Face shape describes visible proportions in one photo. It is not bone structure — a phone camera cannot see bone. Two people with the same label can have very different underlying anatomy.
We do not measure skin, and this is not a beauty rating. No shape is better than another; they call for different styling.
Frequently asked questions
How do I find my face shape?
Upload a photo taken straight on, with your hair away from your temples, and we measure three ratios across 478 landmarks: face length versus width, jaw versus cheekbone, and forehead versus cheekbone. The combination places you in one of seven shapes. It takes a few seconds and runs in your browser.
What if my face is between two shapes?
We show the closest match and an alternative in the full report. The labels describe this photo, and different photo conditions can change the ranking.
Is this face shape detector free?
Yes. The detector, your shape, the alternative match and the three ratios behind your label are free, with no account and no usage limit. Paid reports and PDF delivery are not available yet.
Does it work the same for men and women?
Yes. The measurement is geometric and identical for both — the same three ratios and the same seven shapes. We do not use a gender model, because the geometry does not have one.
Do I need to sign up?
No. There is no account, no email required, and no limit on how many times you run it.
Is my photo uploaded?
No. The scan runs in your browser from 478 landmarks, and the photo never leaves your device. Nothing is stored on our servers.
