Face shape detector

Measures four proportions of your face and matches them to the closest of six shapes: oval, round, square, heart, oblong or diamond, with how confident the match is.

What the detector measures

The scan places 478 landmarks on your face, including along the jawline, across the cheekbones and at the hairline edge of the forehead. The detector takes four measurements from the front view:

  • Length to width: forehead to chin, against the width across the cheekbones.
  • Forehead to jaw: whether the face is wider at the top, at the bottom, or even.
  • Jaw angle: how sharply the jawline turns at the corners, in degrees.
  • Cheekbone width: whether the cheekbones are clearly the widest part of the face.

The four values are matched against six shapes with thresholds documented in the code, and the closest match is returned with a confidence.

The six shapes

  • Oval: longer than wide, forehead slightly wider than the jaw, a rounded jawline.
  • Round: length close to width, cheekbones widest, a soft jaw angle.
  • Square: length close to width, forehead, cheekbones and jaw of similar width, a defined jaw angle.
  • Heart: wide forehead and cheekbones tapering to a narrow jaw and chin.
  • Oblong: clearly longer than wide, with forehead, cheekbones and jaw of similar width.
  • Diamond: cheekbones clearly wider than both forehead and jaw.

A shape is a description, not a grade. Its use is practical: choosing a haircut that adds height or width, frames that contrast with the outline, a beard that changes how the jaw reads. For the full method, including how to cross-check by hand with a tape measure, read the face shape guide.

Reading the confidence

Confidence runs from 0.5, a tie between the two closest shapes, to 0.95. Above about 0.8 your proportions sit clearly inside one shape; between 0.6 and 0.8 they lean toward it. Near 0.5 you are between two shapes, and the result will flip between them across scans. That is the honest answer for many faces: the categories have edges, faces don’t.

What changes the result

  • Lens distance. A phone held close makes the face read narrower and therefore longer. Prop it at arm’s length or further.
  • Hair. A fringe hides the top of the forehead; hair over the cheeks or jaw narrows the width. Pull it back.
  • Head pitch. Chin up or down changes the apparent length. The scan only measures the front view when your head is level.
  • Expression. A smile widens the lower face and can push the result toward round.
  • Light. A shadow along the jaw hides its edge. Face even light.

What the full report adds

The free result is your shape and its confidence. The Full Face Report costs $9, paid once, and adds the four ratios behind it, hairstyle, glasses and beard advice for your shape, your attractiveness score broken into its components, your profile and canthal tilt. It is built on your device from the same scan.

The same scan also gives your attractiveness score and canthal tilt.

Questions

Questions about the face shape detector

Is the face shape detector free?

Yes. The shape and its confidence are free, with no account or email. The Full Face Report ($9, once) adds the ratios behind the shape and hairstyle, glasses and beard advice for it, along with your attractiveness score breakdown, profile and canthal tilt.

How accurate is it?

The measurements are precise; the categories are not. Face shapes are a stylist’s vocabulary with no agreed boundaries, so the detector uses documented thresholds and reports a confidence. High confidence means your proportions sit clearly inside one shape. Low confidence means you are between two, which is common, and the advice for both applies.

Why do I get a different shape on different scans?

If your proportions sit near a boundary, small changes tip the result: a phone held closer makes the face read narrower and longer, a smile widens the lower face, and hair over the forehead shortens it. Scan in the same setup with your hair back and a neutral face, and go with the shape that comes up most.

What if my face is between two shapes?

Then the confidence is lower and the second shape is worth reading about. Oval and oblong, and round and square, are the most common pairs. Styling advice for neighbouring shapes overlaps a lot, so you lose little by choosing either.

Does face shape affect the attractiveness score?

Not as a label. The score never uses the shape name. It does use some of the same measurements, such as jaw width against cheekbone width, inside the jaw and chin component.

Is my face uploaded?

No. The landmarks are found by Google’s MediaPipe Face Landmarker running in your browser and the ratios are calculated there. Nothing about your face is sent to a server. The only request we make is Stripe checkout if you buy the report, and it carries nothing about your face.
