Waist to Hip Ratio Calculator

The waist-to-hip ratio is the circumference of your waist divided by the circumference of your hips. It is used to assess the distribution of body fat and identify risk for cardiovascular disease, type 2 diabetes, and metabolic syndrome.

Measure your waist at its narrowest point, typically about 1 inch above your belly button. Stand relaxed, breathe out naturally, and measure at the end of a gentle exhalation without pulling in your stomach.

Measure your hips at the widest point of your buttocks. Stand with your feet together and the tape measure level and parallel to the floor all the way around.

Men and women naturally distribute fat differently. Women typically carry more subcutaneous fat (under the skin), while men tend to accumulate more visceral fat (around internal organs). The thresholds reflect these biological differences and their associated health risks.

WHR and BMI measure different things. BMI measures overall body size but cannot distinguish between fat and muscle or indicate fat distribution. WHR specifically measures abdominal obesity, which is strongly linked to cardiovascular risk. Using both together gives a more complete picture.

A combination of regular aerobic exercise, strength training, and a calorie-controlled diet reduces overall body fat and abdominal fat specifically. Spot reduction of abdominal fat is not possible, but total body fat loss reliably reduces waist circumference over time.
