WHR Calculation

WHR = waist ÷ hip ; both values in the same unit.



Waist size

Find the top of your hip bone and the bottom of your ribs. Breathe out normally. Place the tape measure midway between these points and wrap it around your waist.

Hip size

Your natural waist is the smallest part of your torso, where your body dips in. Your hips are below that, and they are usually wider than your waist. Your hip measurement includes your butt and your hips. Your hip measurements should be taken at where your hips are the widest. That's because when you're taking measurements, you're trying to get an accurate representation of your body, and the hips represent the widest point on your bottom half.
