Free Face Shape Detector
Upload a photo or use your camera. Our AI face shape analyzer detects your face shape in under 3 seconds — then shows exactly which hairstyles, glasses & beard styles suit you.
What is a face shape detector? A face shape detector is a free AI tool that identifies whether your face is oval, oblong, round, square, heart, diamond, or triangle. It works by mapping facial landmarks on a photo or live camera image, measuring your face length, forehead, cheekbone, and jaw widths, and comparing those proportions against the geometric definition of each shape. This detector (also called a face shape analyzer, finder, identifier, scanner, or test) runs entirely in your browser, so your photo is never uploaded. You can also try the face shape calculator with manual measurements or the face shape quiz without any tools at all.

What Is My Face Shape?
Your face shape is decided by four numbers. They are your face length, forehead width, cheekbone width, and jaw width. The way these four compare to each other places your face in one of 7 shapes.
Here is the quick logic the detector uses:
Not sure where you fall? The AI face shape detector at the top of this page measures all four values from a single photo and shows your match score for every shape. Want even more precision? The face shape calculator uses your actual measurements for 92%+ accuracy.
How to Know Your Face Shape (3 Reliable Methods)
There are three trusted ways to find your face shape. Pick the one that fits how you like to work.
- 1AI photo detection (fastest). Upload a front-facing photo or use the live camera above. The analyzer maps 68 landmarks and identifies your shape in under 3 seconds with a confidence score.
- 2Manual measurements (most precise). Measure your forehead, cheekbones, jaw and face length with a soft tape, then enter them into the face shape calculator. Careful measuring reaches 92%+ accuracy.
- 3The mirror trace method (no tools). Pull your hair back, look straight into a mirror, and trace your face outline with a washable marker. Compare the outline to the 7-shape chart above.
Whichever method you choose, check two things: your length-to-width ratio and which of the three widths is largest. Those two signals separate all 7 shapes.
Face Shape Detector and Hairstyles: Why It Matters
Your face shape is the single best guide for choosing a haircut. The right cut balances your natural proportions. The wrong one exaggerates them.
After you run the detector, scroll to the style guide above for the full do-and-avoid lists matched to your exact result, including the popular pixie cut (best on oval and heart shapes, workable on round with added crown height).
