1. Measure across the top of your cheekbones. Place the end of your tape measure just past the outer corner of your eye. This is your start point. Then, carefully lay the tape measure in a straight line across the bridge of your nose to just past the outer corner of your other eye. This is your end point of measurement. The tape measure should be resting on the top of the "apples" of your cheeks, or just on top of your cheekbones.
2. Measure your jaw line next. Start on one side of your jaw at the base near your ear. Run the measuring tape along your jaw line until you come to the middle of your chin.Multiple the number at the end point by two and write down this measurement.
3. Measure your forehead now. Place the start point of the measuring tape on one side of your forehead at the widest point halfway between your eyebrows and your hairline. Run the measuring tape along your forehead until you come to the same point on the opposite side of your head.
4. Measure the length of your face. Start at the middle of your hairline. Run the measuring tape down your face, over your nose, to the tip of your chin.
