An AI face shape detector analyzes a photo of your face and classifies it into a shape category — oval, round, square, heart, diamond and more. Instead of holding a ruler to a mirror, you take a selfie and the model does the measuring for you in seconds.

How does a face shape detector work?

Behind the scenes, the detector follows the same steps a stylist would — just faster and more consistently:

  • Face detection — it finds your face in the photo and isolates it.
  • Landmark mapping — dozens of points are placed along your hairline, brows, eyes, cheekbones, jaw and chin.
  • Ratio analysis — it compares face length to width, and forehead width to cheekbone and jaw width.
  • Classification — those ratios are matched to the closest shape category and returned with a confidence read.

How to use the detector

1

Add a photo. Take a front-facing selfie or pick a clear portrait from your gallery — no sign-up.

2

Detect. The app maps landmarks and measures your facial ratios entirely on your device.

3

Get your shape. Your detected face shape appears with a description and tailored hairstyle, glasses and accessory tips.

How accurate is a face shape detector?

For a clear, front-facing, evenly lit photo, AI detection is highly consistent — it removes the human tendency to "see" the shape you expect. Accuracy drops when the face is turned, tilted, partly hidden by hair, or lit from one side. If two scans disagree, it's almost always a photo issue, not your face.

Get the most accurate result

  • Pull hair back so your entire hairline and jaw are visible.
  • Look straight into the camera at eye level, neutral expression.
  • Use soft, even lighting — no strong shadow on one cheek.
  • Fill the frame with your face and keep it in focus.
