A face shape detector that tells you what to do with it

Upload one selfie and Glancely detects your face shape — oval, round, square, heart, oblong, or diamond — from measured proportions, not a quiz. You get the label, the secondary blend most faces actually have, and the part other detectors skip: the hairstyles that follow from it, previewed on your own photo.

Why detection beats the mirror-and-tape method

The classic advice — trace your reflection on the mirror, measure with a tape, compare against a chart — fails where it matters. You're judging angles on a curved surface, from arm's length, with a strong incentive to round yourself into the flattering category.

A detector working from a straight-on photo measures the same landmarks every time: forehead, cheekbone, and jaw width, face length against that width, the angle of the jaw, the finish of the chin. The pattern of those ratios is your shape — and the measurement doesn't care what you were hoping to hear.

What the detector measures

  • Forehead, cheekbone, and jaw width — and how the three compare
  • Face length relative to width
  • Jaw angle and chin shape, which separate the near-miss categories
  • Thirds balance and symmetry, folded into the full facial read

How to detect your face shape with a photo

  1. Take or upload one straight-on selfie — hair pulled back helps the jawline read.
  2. Glancely measures your proportions and classifies the pattern.
  3. You get a primary shape plus a secondary blend when you sit between categories.
  4. The result flows straight into hairstyle recommendations you can preview on your own face.

Not a quiz

Face shape quizzes ask you to self-report the measurements — which is the exact task people are bad at. Here the photo answers the questions.

Blends, not boxes

Most faces are two shapes at once. The detector reports oval with square tendencies rather than forcing a single box — because the blend changes the advice.

The answer has a next step

A label alone is trivia. Detection here feeds recommendations: cuts chosen for your proportions, each one rendered on your photo before you commit.

From detected shape to decided haircut

The reason to detect your face shape was never the label — it's the decisions downstream. Width at the cheeks argues for height on top; a long face wants horizontal weight; a strong jaw softens under texture. Your shape is the input to all of it.

Once Glancely has the measurement, it carries you the rest of the way: hairstyles matched to your face shape, and every candidate previewed on your own photo so the theory gets checked against your actual face.

Face shape detection

Is there an app that detects your face shape?

Yes. Glancely is a face shape detector, free to download on iOS. One selfie is measured across forehead, cheekbone, and jaw width, face length, jaw angle, and chin shape, and classified as oval, round, square, heart, oblong, or diamond — with the reasoning shown, not just the label.

How does a face shape detector work?

It measures the ratios a stylist eyeballs: how your forehead, cheekbones, and jaw compare in width, how long the face runs against that width, how sharp the jaw angle is, and how the chin finishes. The pattern of those ratios is what separates one shape category from another.

What if I'm between two face shapes?

Most people are. A single hard label is the weakness of quiz-style detectors — real faces blend categories. Glancely reports a primary shape plus a secondary blend, like oval with square tendencies, because the blend changes which hairstyles actually work.

Is there a free app to detect my face shape?

Glancely is free to download on iOS. One selfie is all the detector needs, and the result comes back as a primary shape with a secondary blend — along with the rest of the facial read your hairstyle recommendations are built on.

How accurate is an AI face shape detector compared to measuring by hand?

More consistent, mostly. Hand-measuring with a tape and a mirror fails at the hard part — judging angles and proportions on a curved surface from a bad vantage point. A detector working from a straight-on photo measures the same landmarks every time and isn't tempted to round toward the shape you were hoping for.

What should I do once I know my face shape?

Use it. The shape is only useful as an input: it tells you which haircuts add balance and which fight your proportions. In Glancely the detection flows straight into recommendations, and every suggested cut can be previewed on your own photo before you commit.

Detect it, then decide with it.

One selfie returns your face shape, your blend, and the haircuts built for both — previewed on you.
