How to Measure Accurately

Waist

Measure at navel level, relaxed (don't suck in). Take measurement after exhaling normally.

Neck

Measure just below the Adam's apple (larynx). Keep the tape level and snug but not tight.

Hip (Women)

Measure at the widest point of your buttocks with feet together.
