Waist to hip ratio

Your waist to hip ratio estimates the fat distribution in your body. Find out how this can affect your overall health with this interactive tool.

Regardless of your height and build, a relative excess of fat around your waist appears to increase your risk of developing one or more chronic diseases or conditions such as heart disease and diabetes. One way doctors recommend assessing your weight-related risk is by measuring your waist circumference in relation to your hip circumference.


Measure the circumference of your waist and hips in centimetres. Your waist circumference is measured at the narrowest point between your ribs and hips after exhaling. Once you have taken this measurement, insert it in the box on the left.

Your hip circumference is measured at the point where the buttocks are most extended when viewed from the side. Insert this measurement in the box on the right.

Waist and hip measurements and the advice below are appropriate for adults only and recommended ratios differ based on your age and gender. Enter your age and select the appropriate gender where indicated. Then click ‘Calculate’ for your waist-to-hip ratio and an explanation of how to interpret the result in terms of your health risk.
