How do AI face shape detectors work?

AI face shape detectors look at the outline of your face and compare proportions: forehead, cheekbone and jaw width, face length and chin shape. This one uses a vision model that judges the underlying shape even when hair covers part of it, then turns the result into haircut and glasses picks.

How to check my face shape at home without a photo tool?

Pull your hair back and measure four lines with a soft tape: forehead width, cheekbone width, jaw width and face length from hairline to chin. If the cheekbones are widest you are likely oval or diamond; a widest forehead suggests heart; a widest jaw suggests triangle; similar widths suggest square, round or oblong depending on length.

Are online face shape detectors reliable?

Treat any result as an informed estimate. Online face shape detectors depend on the photo: a tilted head, a wide-angle selfie, a big smile or hair over the jaw can shift it. That is why the report shows match percentages instead of one hard label. For the clearest read, use the photo tips above.

Can I find my face shape online free?

Yes, it is free to try. New accounts get free credits at sign-up for a free face shape analysis; after that, each analysis costs 1 credit, refunded if the photo has no usable face.

Which face shapes can it detect?

Seven: oval, round, square, heart, diamond, oblong (also called rectangle or long) and triangle (also called pear). Many faces mix two shapes, which the match percentages show.

Why did I get a different face shape from another photo?

Camera distance, lens distortion, head tilt, expression and hairstyle all change how wide or long a face looks. Use a front-facing photo taken from at least an arm’s length away, at eye level, with your hair back, and compare two or three photos.

Can it tell what face shape does this person have in any photo?

Only use photos of yourself or of people who agreed. The face shape detector describes the shape of the face in the photo; it never identifies who the person is.

Does it work for men, women, beards and long hair?

Yes. It judges the underlying bone structure, so beards, bangs and long hair are fine, although a hairline and jawline that are visible give the clearest result. Haircut picks follow the hair in your photo.

What Is a Face Shape Detector?

A face shape detector is an AI tool that looks at a front-facing photo and tells you which of the seven common face shapes yours is closest to: oval, round, square, heart, diamond, oblong or triangle. This online face shape analyzer works as a face shape scanner and face shape recognizer in one: it compares the width of your forehead, cheekbones and jaw, the length of your face and the line of your chin, then shows how close you are to each shape.

Instead of measuring yourself in the mirror, you upload one selfie and get face shape detection with reasons: a match percentage for each shape, the measurements, the traits that decided it, four haircuts and three glasses styles that suit you, and two things to avoid. It is a face shape finder online with face shape recognition online in your browser: it works like an AI face shape detector app, without the download.

Use the result as a styling guide, not a measurement certificate: hair, camera angle and expression change how a face reads, and many faces sit between two shapes. Free to try with sign-up credits, then 1 credit per analysis.

Face Shape Chart: The 7 Shapes the Detector Finds

How each face shape is measured. The highlighted lines are the ones that decide it.

Oval

Longer than wide (about 1.5 to 1), cheekbones a little wider than a curved forehead and jaw, rounded chin. Most haircuts and frames work.

Round

Length close to width, full cheeks and a soft jaw without sharp corners. Height on top and angular frames add length.

Square

Forehead, cheekbones and jaw about the same width, a strong angular jaw and a flat chin. Soft layers and round frames ease the angles.

Heart

Wide forehead and cheekbones, a narrow jaw and a pointed chin. Volume near the jaw balances the forehead.

Diamond

Cheekbones clearly widest, with a narrow forehead and a narrow, pointed chin. Fringes and chin-length cuts fill out the narrow areas.

Oblong

Clearly longer than wide, with straight sides and a forehead, cheeks and jaw of similar width. Side volume and bangs shorten it.

Triangle

Jaw widest and forehead narrowest, also called a pear shape. Volume at the crown and frames wider on top balance the jaw.

A Match Score for Every Shape

Faces are rarely one pure shape. The report names your closest shape and how much you also match the others, for example 45% square with a touch of oval and oblong, so the what is my face shape AI answer comes with nuance instead of a single label.

Who Uses an Online Face Shape Detector

Style board from a face shape analysis: haircut, glasses and beard ideas

Before a Haircut

Scan your face shape before the salon or barber and bring a short list of cuts that suit you, with the reasons, instead of one screenshot.

Choosing Glasses or Sunglasses

Narrow hundreds of frames down to the three styles that balance your proportions, then try them on virtually.

Shaping a Beard or Brows

A square jaw, a round face or a narrow chin each call for a different beard or brow shape. The report tells you where to add or remove volume.

Makeup, Contour and Styling Clients

Know where to contour and place blush, or give stylists and barbers a quick starting point for a consultation.

How to Find the Face Shape by Hand, or Get a Better Scan

A good photo gives the AI a clear outline. The same four measurements also work with a tape measure.

Pull Your Hair Back

Tie your hair back or tuck it behind your ears so the forehead, temples and jawline are visible.

Face the Camera in Even Light

Hold the camera at eye level, look straight ahead and avoid strong shadows that hide the jaw or cheekbones.

Measure Four Lines

To analyse face shape by hand, measure forehead, cheekbone and jaw width plus face length, then compare them with the chart above.

Keep a Neutral Expression

Relax your face. A big smile lifts and widens the cheeks and can make a face read rounder than it is.
