How the calculator decides
Your face shape comes from the proportions between four measurements — face length, forehead width, cheekbone width, and jaw width — plus how your chin finishes. No single measurement matters on its own; the calculator compares the ratios the same way a stylist's eye does: is the face clearly longer than it is wide, which of the three widths is largest, and does the jaw read soft, squared, or pointed?
Measuring accurately
Pull hair fully back, face a mirror in good light, and use a soft measuring tape held straight (not curved around the head): forehead at its widest point between the temples, cheekbones across the most prominent points, jaw from just below one ear to the other across the chin line, and length from the centre of the hairline to the chin tip. The diagram above lights up each line as you type.
The seven classic shapes
Oval — longer than wide, cheekbones widest, soft jaw; suits nearly every style. Round — length ≈ width with soft edges; angles and height add definition. Square — width ≈ length with a strong jaw; softening layers balance it. Heart — wide forehead narrowing to a pointed chin; volume near the jaw balances it. Oblong — clearly long; width-adding styles shorten it visually. Diamond — cheekbones dominate a narrower forehead and chin. Triangle — jaw wider than the forehead; volume on top rebalances.
Face shape is a styling guide, not a rule — lighting, hairline and expression all shift how a face reads, and most real faces blend two shapes.
