Waist-to-Hips Ratio (WHR) is the calculated by dividing a person’s waist measurement by their circumference at their hips. Waist is measured at the narrowest point of one’s midsection between their bottom rib and the top of their hipbone. This is usually one inch above the navel. Hips are measured at the widest point below the tip hip bone. Both measurements are taken parallel to the floor when standing straight.

Fat around the waist has been linked to increased risk of cardiovascular disease. The following are considered healthy WHR values.
