AI face shape analysis

Know your face shape from one photo

Glancely is an app to know your face shape without a mirror, a tape measure, or a guess. Upload one selfie and AI identifies your face shape — oval, round, square, heart, oblong, or diamond — then shows you the proportions it read to get there.

Knowing your face shape is a measurement, not an opinion

Face shape comes down to four numbers and one angle: how wide your forehead is, how wide your cheekbones are, how wide your jaw is, how long your face is, and how sharply the jawline turns at the corner. Whichever width wins, and how soft or square that turn is, decides the category.

That comparison is hard to run on your own face. You see it head-on every day, hair covers the hairline, and phone cameras distort the proportions at close range. Landmark detection does the same comparison the same way every time.

That's why "what shape is my face?" gets a different answer from every chart you hold yourself up to. Self-assessment goes wrong in predictable ways. A soft jaw makes people call a round face oval. Nobody measures length, so long faces get called oval too. And anyone with a fringe ends up guessing at the forehead. A face shape app that finds your face shape from measurements skips all three.

What Glancely measures

  • Forehead width, measured across the outer ends of the brows
  • Cheekbone width at the widest point
  • Jawline width, how fast it tapers, and the chin angle in degrees
  • Chin type — pointed, rounded, squared, or cleft
  • Face length and the balance of the upper, middle, and lower facial thirds
  • Overall symmetry between the two sides

How to know your face shape in Glancely

  1. Take a front-facing selfie in even light, hair back off the forehead, face relaxed.
  2. Glancely maps 76 facial landmarks on-device, corrects for any head turn or tilt, and compares the widths, lengths, and angles between them.
  3. You get your primary face shape, plus a secondary blend when your proportions sit between two categories.
  4. Every observation comes with the reasoning behind it, so you can see what drove the result.

One photo, no measuring

No string, no ruler, no tracing your outline on a bathroom mirror. A single clear selfie carries every proportion the read needs.

A blend, not a box

Most faces are not a textbook oval or a textbook square. A primary shape with a secondary blend describes real proportions more honestly than one label.

Reasoning you can check

The result names the measurements it turned on. If your jaw is nearly as wide as your cheekbones, you see that — not just the word it produced.

The six face shapes, and what tells them apart

Oval

Face length noticeably greater than cheekbone width, forehead slightly wider than the jaw, and a gently rounded jawline. The most balanced set of proportions.

Round

Face length and cheekbone width close to equal, with soft angles throughout and a rounded chin. Width sits at the cheeks.

Square

Forehead, cheekbones, and jaw close to the same width, with a sharp, defined turn at the jaw corner and a flat-edged chin.

Heart

Widest at the forehead and cheekbones, tapering to a narrow, often pointed chin. A widow's peak is common but not required.

Oblong

Face length clearly dominant, with forehead, cheekbones, and jaw of similar width — an elongated version of square or round.

Diamond

Cheekbones the widest point by a clear margin, with both a narrow forehead and a narrow, pointed chin.

Knowing the shape is step one — the haircut is step two

A face shape on its own does not tell you what to ask for at the salon. It tells you which silhouettes, lengths, volume placements, and parting directions are working with your proportions instead of against them.

Glancely carries the read straight through: once it knows your face shape, it factors in hair texture, density, length, movement, and skin undertone to build a personalized shortlist — then renders the strongest options on your own photo from the front, side, and three-quarter.

What your face shape decides

  • Where the volume goes — on top, at the sides, or at the jaw
  • Where the length stops relative to the chin
  • Whether a fringe opens the face or crowds it
  • Centre part or side part
  • How close the sides can come in

Knowing your face shape

How do I know my face shape?

Compare four measurements: forehead width, cheekbone width, jawline width, and face length. Whichever is widest, and how sharply the jaw turns, decides the category. Glancely reads all four from a single front-facing selfie so you do not have to measure anything by hand.

Is there an app to know your face shape?

Yes. Glancely is an app to know your face shape from one photo. It identifies your primary face shape, notes a secondary blend when your proportions sit between two categories, and shows the reasoning behind the read.

How do I find my face shape with an app?

Give it a photo it can measure. Use the rear camera or have someone else take it from about two metres away, because an arm's-length selfie exaggerates the centre of the face. Keep the expression neutral, since a big smile lifts and widens the cheeks. Take your glasses off and get your hair off the forehead and away from the jaw. Then the app does the rest: Glancely maps the landmarks, measures the proportions, and gives you a primary shape with a blend if you sit between two.

Can my face shape change?

The bone structure underneath doesn't, but the shape a camera sees can. Weight gain or loss changes fullness at the cheeks and along the jaw, which can move a face between round and oval or soften a square jaw. Age redistributes soft tissue in a similar way. If your weight has shifted noticeably since your last read, run it again, because the haircut that suits the face you have now is the one worth booking.

Can AI determine my face shape?

Yes. AI face shape detection works by locating facial landmarks and comparing the ratios between them, which is more consistent than judging your own face in a mirror. Glancely reports the proportions it measured and how confident the call is, so you can see why it landed on a shape rather than taking the label on faith.

What are the different face shapes?

The six common categories are oval, round, square, heart, oblong, and diamond. Most faces are not a textbook match for one — a primary shape with a secondary blend describes real proportions more accurately.

Is there a free app for face shape and hairstyle?

Yes. Glancely is free to download on iOS, and knowing your face shape costs nothing: one selfie names your primary shape and any secondary blend, with a detailed read of your face alongside it. From there it reads your hair traits and previews recommended styles on your own photo, with Glancely Premium opening up unlimited try-ons and advanced recommendations.

Why does knowing my face shape matter?

Face shape decides which silhouettes, lengths, volume placements, and parting directions balance your proportions. It is the starting point for a haircut decision, though hair texture, density, and skin undertone matter just as much for the final recommendation.

Know your face shape for certain.

One selfie, a stylist-grade read of your face, hair, and skin, and the styles built for it.
