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 — 76 of them, mapped on your phone the moment the photo is taken: forehead, cheekbone, and jaw width, face length against that width, the angle of the chin in degrees, how fast the jaw tapers. It corrects for a turned or tilted head, and reports how confident the call is. 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
  • Chin angle and jaw taper, 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 maps 76 facial landmarks on your phone, measures the proportions between them, and classifies the pattern against six calibrated shape profiles.
  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.

Detector, scanner, calculator, or online tool?

Search for a way to detect your face shape and you'll find four kinds of tool. They all try to answer the same question, and they differ in where the numbers come from. A face shape calculator takes measurements you type in, so it can only be as accurate as your tape and your guess at where the hairline starts. A face shape scanner runs on the live camera and makes a quick call while your face moves. An online face shape detector takes a photo you upload in a browser, which is handy on a laptop. Most of them return one label and stop there.

A face shape detector app works from a still photo on the device that took it. That's where the extra precision comes from. The landmarks are mapped on the phone, so head turn and tilt can be measured and corrected for. The confidence of the call can be reported honestly. And the result stays connected to everything that follows it, from hair type to the haircuts worth trying. If you're using a laptop, any detector will give you a starting label. If the answer is going to decide a haircut, use the one that measures.

What any detector should give you

  • Proportions measured from the photo, not typed in or self-reported
  • A secondary blend when you sit between two shapes
  • A confidence level that drops for a turned or tilted head
  • The measurements behind the label, so you can check them
  • A way to run it on a photo you already have

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.

Your shape's first move

  • Round: height on top, length that ends below the chin
  • Square: soft texture where the jaw turns
  • Oval: free to follow your hair type
  • Heart: fullness at the jaw, lightness at the temples
  • Oblong: width at the sides, a fringe to take off length
  • Diamond: fullness at forehead and chin, close at the cheekbones

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.

Is there an online face shape detector?

Yes, several websites will detect a face shape from a photo you upload in the browser, and they're a reasonable first pass if you're on a laptop. Glancely is an app rather than a website, and that's deliberate: mapping the 76 landmarks on the phone that took the photo is what lets it correct for head turn and tilt, report how confident the call is, and carry the result straight into hairstyle recommendations.

Can I detect my face shape from a photo I already have?

Yes, as long as the photo is a good one. Upload an existing picture instead of taking a new selfie and the detector reads it the same way. Pick one that's straight-on, in even light, without a filter, and taken from a little distance rather than at arm's length — a close-up wide-angle selfie stretches the middle of the face. If the photo would skew the result, Glancely flags it and suggests a retake.

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?

Yes. Glancely is free to download on iOS, and the detection itself is free: one selfie comes back as your primary face shape with a secondary blend, alongside much of the facial read your hairstyle recommendations are built on. Glancely Premium opens up the rest.

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.
