Face Shape Detector: What Is My Face Shape?
Upload a photo and get all seven face shapes ranked as a distribution, not one label. The detector measures three width ratios plus the jaw corner and chin taper angles, because width alone cannot tell a square face from a round one — and your image never leaves the browser.

Before you analyze
- 1Use your own photo, or one you have permission to use.
- 2One adult face only. No minors or age estimation.
- 3Results describe this photo, not objective beauty or health.
A typical first run loads about 15 MB of model/runtime files, then the browser caches them. Nothing is submitted to our analysis API.

The first run can take a moment. Your photo remains on this device.
We could not analyze this photo
Your photo and landmarks stay in page memory and are cleared when you reset or leave. Face-shape tools keep a small result summary in this tab for up to 30 minutes so you can continue to hairstyles or glasses. Clear the result to remove it.
Scan your face with the camera
Keep one face in view and look straight ahead while the scanner collects usable frames. It measures five contour features across several seconds. This camera mode is a beta; multi-frame analysis has not been validated as more accurate than a photo.
Include your forehead, cheeks and chin. Use even front lighting and keep hair away from the outline.
Camera frames stay in this browser. The camera stops when the scan ends, you cancel, switch modes or leave this tab.
Confirm the statement above to start. The first run also needs to download the local model.
0 usable frames
If the camera cannot start, use a photo or enter manual measurements.
Or measure your face yourself
Take four measurements with a tape or ruler and answer two questions about your jaw and chin. This runs the same seven-profile classifier as the photo tool, without loading the face model.
Four measurements
Use any unit you like — centimetres, inches, anything — as long as all four use the same one. Only the ratios between them are used.
Across the widest point of your forehead, roughly halfway between your brows and hairline.
Across the top of your cheekbones, from the outer corner of one eye to the other.
From below one ear to below the other, at the corner where the jaw turns toward the chin.
From the centre of your hairline straight down to the bottom of your chin.
Enter all four measurements to continue.
Your ranking appears here
All seven profiles are scored, so you can see how close the runner-up is.
Hand measurements are less repeatable than landmark detection, especially at the forehead and jaw. Treat this as a cross-check on the photo result rather than a replacement for it.
How the detector tells close face shapes apart
An oval and oblong face can taper similarly; face length helps separate them. Round and square contours can have similar widths; the jaw corner becomes more useful. The result ranks all seven profiles so you can compare the leading matches.
- Length and widths
- Show which part of the contour is longer or wider.
- Jaw and chin angles
- Describe a curved corner, a defined turn or a pointed taper.
- Match shares
- Show relative similarity to our profiles, not a diagnostic probability.

Face shape guides
Each guide covers how to identify the shape, the reference measurements behind it, and hairstyle, glasses, beard, contour and accessory starting points.
Oval
Moderately long, with the forehead a little wider than the jaw and a softly rounded chin.
Read guide →
Round
Similar in length and width, with a soft jaw that curves instead of turning a corner.
Read guide →
Square
Short and wide like a round face, but with a jaw that turns a clear corner below the ear.
Read guide →
Oblong
The longest of the seven profiles, with widths that stay fairly even from forehead to jaw.
Read guide →
Heart
A wide forehead narrowing to a pointed chin, often with a widow's peak.
Read guide →
Diamond
Widest at the cheekbones, with both a narrow forehead and a narrow, pointed chin.
Read guide →
Triangle
A jaw wider than the forehead — the inverse of the heart profile.
Read guide →Evidence behind this result
The output is built from inspectable photo geometry and a separate image-quality signal.
Width relationships
Measures forehead, cheek and jaw widths relative to the cheek contour.
Contour angles
Adds the jaw corner angle and the chin taper angle, which separate square from round and pointed from broad.
Full distribution
Ranks all seven reference profiles with normalized similarity shares instead of forcing a single label.
How this tool works
1. Trace
Visible face-oval and key width landmarks define the photo contour.
2. Measure
Three scale-independent width ratios and two contour angles are taken from the landmark set.
3. Rank
Each of the seven profiles is scored on all five measurements and converted into a match percentage.
What the result cannot tell you
01
Hair, facial hair, pose and camera perspective can obscure the true contour.
02
Most people sit between shape categories; the confidence score reflects separation between matches.
03
The labels are styling shorthand, not biological or medical classifications.
About this tool
How local processing works →Can I have more than one face shape?+
Yes. Face shape is continuous, which is why this detector ranks all seven profiles with a percentage each. When the top two are within about ten points, both are reasonable descriptions of the same face.
How is a square face different from a round one?+
Not by width. Both are relatively short and wide, so the difference is the jaw corner: a square contour turns sharply toward the chin, a round one curves. This detector measures that angle directly rather than inferring it from width ratios.
Should I pull my hair back?+
If possible. A clear forehead, cheek and jaw outline gives the detector better visible evidence, and the forehead width is the measurement hair affects most.
Is the result stored?+
Detection runs locally. A summary of the seven shape weights and five measurements stays in this tab for up to 30 minutes so hairstyle and glasses pages can reuse it. The summary does not include your photo or landmarks. You can clear it from the result.
