Waist-to-Hip Ratio Calculator
Your waist-to-hip ratio is your waist measurement divided by your hip measurement. Enter both in the same unit and get the ratio. This calculator shows the number and applies no cut-off.
Worked example
A waist of 85 cm and hips of 95 cm give a waist-to-hip ratio of 0.89.

Results are estimates from published formulas, not medical advice. Your own body can sit above or below them.
Where the formulas come from, and how we check them: how we calculate.
The calculation
Waist ÷ hips, in the same unit. An 85 cm waist and 95 cm hips give 85 ÷ 95 = 0.89. It is a ratio, so centimetres and inches give the same answer.
Why this page shows no category
The World Health Organization held an expert consultation on waist circumference and waist-hip ratio in Geneva in December 2008 and published its report in 2011; one stated objective was to define potential cut-off points for public health action. We link the report so you can read what it says in its own words, and we do not apply a cut-off here: which value counts as raised depends on the population and the purpose, and a number from a web page cannot tell you that.
How to measure
- Use a flexible tape, flat against the skin, snug but not pressing, and measure relaxed.
- Waist: the same place every time. Guides differ on exactly where it is.
- Hips: around the widest part of the buttocks, tape level all the way around.
- Stand with your feet together, and measure without bulky clothes.
Reading the number
A ratio goes down if the waist gets smaller or the hips get bigger, so it can change without your waist changing. If you track it, look at the waist and hip measurements as well. For a ratio against height instead, use the waist-to-height ratio calculator. If you are pregnant, have a medical condition, or are worried about your weight or your body, talk to your doctor. This page makes no health claims about any result.
