Measure with a ruler
Most precise · Takes 5 minutes

For the most definitive answer, take four quick measurements. You'll need a flexible tape measure (or a ruler and a mirror).

Step 1: Prepare

Tie your hair back so your hairline and jaw are visible. Stand in front of a mirror in good light.

Step 2: Measure these 4 points

A
Forehead width — measure across the widest point, roughly halfway between your eyebrows and hairline
B
Cheekbone width — across the widest point of your cheeks, from the outer corner of one eye to the other
C
Jaw width — from one jaw angle to the tip of the chin, then double it
D
Face length — center of hairline straight down to tip of chin

Step 3: Interpret your measurements
