📏 Waist-to-Hip Ratio Calculator

Waist-to-hip ratio shows where your body stores fat. Fat around the waist is linked with a higher risk of heart disease and type 2 diabetes than fat around the hips.

How the Waist-to-Hip Ratio Calculator works

Measure your waist at the midpoint between your lowest rib and the top of your hip bone, and your hips at the widest part. Use the same unit for both. The waist is divided by the hips.

WHR = Waist ÷ Hip WHO: substantially increased risk at WHR ≥ 0.90 (men) or ≥ 0.85 (women)

Step-by-step calculation

  1. 1Measure waist and hips.
  2. 2Divide waist by hips.
  3. 3Compare with WHO cut-offs.

Worked example

A man with a 34-inch waist and 40-inch hips has a WHR of 34 ÷ 40 = 0.85, below the WHO cut-off of 0.90 for men.

Is WHR better than BMI?

It measures something different. Using both gives a fuller picture; neither is a diagnosis.
