How to Measure Your Face Shape at Home

A ruler-and-mirror method that matches what face-classification apps measure: four distances, one ratio, three width comparisons.

You need a flexible tape (or a ruler and a mirror), hair tied back, and five minutes. The measurements below are exactly the ones browser-based face classifiers compute from landmarks — doing them by hand gets you the same answer without uploading anything.

Steps

1. Face length: from the centre of your hairline to the lowest point of your chin. Pull the tape straight down past your nose.
2. Face width: across the widest point of the cheekbones, usually just outside the eye corners. Keep the tape level.
3. Forehead width: across the widest part of the forehead, roughly halfway between brows and hairline.
4. Jaw width: from one jaw corner to the other, measured just below the ears at the angle of the jaw.
5. Now the ratios: length ÷ cheekbone width; forehead vs jaw (which is wider?); and look at the jawline's angle in the mirror — curved, angular, or tapered to a point?

Reading the result

Length ≈ width with a curved jaw → round. Length ≈ width with an angular jaw → square. Length > 1.6× width → oblong. Cheekbones clearly widest with a narrow forehead → diamond. Forehead widest tapering to a pointed chin → heart. Jaw clearly widest → triangle. Ratio near 1.5 with a rounded chin → oval.
