Face shape and hairstyle guide
What the four face widths say about your shape, and the haircut direction that balances each of the seven shapes.
Face shape is a ratio problem, not a mystery: the face length against the cheekbone width, the forehead against the jaw, and the cheekbones against both. Measure those, name the shape, then choose a cut that moves the visual balance where you want it.
How a face shape is measured
The calculator and the scan use the same four numbers. Measure them on a front-facing photo at eye level, or with a tape in front of a mirror.
Face length
Hairline to the bottom of the chin. The scan estimates the hairline from the top of the mesh, so it labels this number as an estimate.
Cheekbone width
The widest point across the cheekbones, just below the outer corners of the eyes.
Forehead width
Across the forehead at its widest point, usually halfway between the brows and the hairline.
Jaw width
Between the two jaw angles, below the ears, where the jawline turns towards the chin.
The seven shapes and the cut that balances each
Every direction below adds width where the face is narrow or softens where it is wide. None of it changes the face; all of it changes what the eye lands on first.
Oval
Length around one and a half times the cheekbone width, forehead slightly wider than the jaw. Most lengths and partings work; keep volume moderate and avoid covering the whole forehead.
Round
Length close to the width, soft jaw. Height at the crown, a side parting and layers that fall below the chin lengthen the face; avoid chin-length blunt cuts and full round fringes.
Square
Forehead and jaw almost the same width, strong jaw angles. Soft layers, waves and side-swept fringes round the corners; avoid blunt lines that end at the jaw.
Heart
Forehead clearly wider than the jaw, narrow chin. Chin-length or longer cuts with width at the jaw, curtain fringes and side partings; avoid heavy crown volume.
Diamond
Cheekbones wider than forehead and jaw. Fringes and width at the forehead, chin-length layers and textured bobs; avoid slicked-back sides that expose the cheekbones.
Oblong
Length well above the width, often with a long midface. Fringes, side volume and shoulder-length cuts shorten the face; avoid extra height on top and very long straight hair.
Triangle
Jaw wider than the forehead. Volume and layers above the jaw, side-swept fringes and crown height; avoid width at the jawline.
From measurement to a haircut decision
Measure or scan Use the face shape calculator with four numbers, or run the free scan and let the landmarks measure the same widths from a photo.
Read the fit, not just the label The result shows a fit score and the runner-up shape. A low fit means you sit between two shapes; borrow advice from both.
Pick a direction, then a stylist Choose the balance you want, take the description to a stylist, and let them adapt it to your hair texture and routine. The full report does this with previews on your own photo.
Face shape questions
Can my face shape change?
The bone structure does not, but the measured shape moves with weight, age, hairline and the photo itself. Measure under the same conditions before comparing results.
What if I am between two shapes?
That is common; the calculator reports a fit score and a runner-up shape for this reason. Take the advice both shapes share and ignore the advice where they disagree.
Does face shape decide the haircut?
It is one input. Hair texture, density, hairline, how much time you spend styling and your own taste matter at least as much. Use the shape to rule out directions, not to pick one.
Do I need a photo?
No. The face shape calculator takes four measurements you can take with a tape in front of a mirror. A photo is only needed for the scan, which measures everything at once.
Are the shape rules the same for everyone?
The rules are ratio thresholds, so they apply the same way to every face, and they are an experimental convention. They do not infer anything about who you are.
