Face Shape Detector – Face Shape Finder for Men and Women

A face shape detector you control

This face shape detector works the way a stylist with a tape measure does. It compares four measurements — forehead width, cheekbone width, jaw width and face length — and tells you which of the common face shapes your proportions are closest to: oval, round, square, oblong, heart, diamond or triangle. You see the measured ratios, the second-closest shape and hair, glasses and beard ideas for your result.

Use it as a face shape finder in two ways. Mark the eight points on your photo by hand, with a magnifier while you drag. Or switch to automatic mode, which loads a face-landmark model into the page and places the markers for you to check. Either way the photo is never uploaded. Face shapes for men and women use the same measurements; only the style ideas differ.

How to use the Face Shape Detector

1. Take a straight-on photo at arm’s length or further, hair pulled back, chin level, no tilt. Choose it in the box (a drawn sample is loaded to start).
2. Mark the left and right forehead edges, the widest points of the cheekbones, the two jaw corners below the ears, the middle of the hairline and the chin tip. Or pick “Detect automatically” and press “Load model and detect”.
3. Drag any marker to fine-tune; a 4× magnifier appears while you drag, and the arrow buttons move the selected marker one pixel.
4. Choose how your jawline looks (soft, angular or pointed chin) if you know.
5. Read your shape, the three ratios, the closest alternatives and the style ideas. Copy the result if you want to show it to your stylist.

How the face shape is worked out

The cheekbone width is the reference. The tool divides face length, forehead width and jaw width by it, giving three ratios, then measures the distance to each shape’s typical ratios in the table above. Forehead and jaw differences of 0.06 count as much as a length difference of 0.10, because widths vary less than length between people. The shape with the smallest distance wins.

Worked example (the sample face): cheekbones 400 px, forehead 344 px, jaw 296 px, hairline to chin 552 px. Ratios are 552 ÷ 400 = 1.38, 344 ÷ 400 = 0.86 and 296 ÷ 400 = 0.74 — exactly the oval row, so it is a clear oval; heart is next. Because only ratios are used, no card or ruler is needed, and the photo’s size does not matter.

The jawline answer adds a penalty to shapes it contradicts: an angular jaw counts against round and oval, a soft jaw against square, a pointed chin against round, square and triangle. That mirrors the stylist rule that round and square faces have similar widths and differ in the jaw corners.

Face shapes at a glance

• Oval — longer than wide, forehead slightly wider than the jaw. The most flexible shape for haircuts and frames.
• Round — length close to width, soft jaw. Angular frames and height on top add length.
• Square — widths nearly equal, strong jaw corners. Round or oval frames and soft layers soften it.
• Oblong — clearly long, similar widths. Width at the cheekbones balances it.
• Heart — wide forehead, narrow jaw. Fullness near the chin balances it.
• Diamond — cheekbones widest, narrow forehead and jaw. Add width above and below.
• Triangle — jaw wider than forehead. Bold-top frames and volume at the crown help.

Getting a reliable reading

Lenses distort faces at close range: a selfie at 25–30 cm makes the middle of the face look wider and the nose bigger. Ask someone to take the photo from 1.5 m or more, or use a timer with the camera at eye level. Keep your head straight; looking up or down changes the face length. Pull your hair back so the hairline and jaw corners are visible, and mark the bone edges, not the hair.

Automatic mode places the top marker on the upper forehead, below most hairlines, so the face length starts short — drag marker 7 to your hairline before reading the result. Beards hide the jaw corners and chin; mark where the bone is, by feel if needed. For glasses, the frame’s size matters as much as its shape, so check the glasses frame size guide and your pupillary distance. For clothing and makeup colours, try the personal color analysis quiz or the skin undertone test.
