Measure on bare skin, relaxed, after breathing out. Waist: midway between the lowest rib and hip bone (this is the site used for waist-risk, waist-to-height and waist-to-hip results). Hip: widest point. Neck: just below the larynx. The US Navy body-fat method wants a different waist site (men: at the navel; women: narrowest point) - see its note below if you use it, since the same number feeds both.
