- Keep the tape level, snug, and not too tight. Measure without thick clothing.
Free Waist-to-Hip Ratio Calculator
A waist-to-hip ratio calculator estimates your WHR by dividing your waist measurement by your hip measurement. This number can give a simple clue about fat distribution, especially abdominal fat.
What Is Waist-to-Hip Ratio?
Waist-to-hip ratio, also called WHR, compares the size of your waist with the size of your hips. A higher WHR may suggest more abdominal fat, which can be linked with higher cardiometabolic risk in some people.
Waist-to-Hip Ratio Formula
The formula is simple. Measure your waist and hips using the same unit, then divide waist by hip.
WHR Formula
WHR = waist circumference ÷ hip circumference
Example
85 cm waist ÷ 100 cm hip = 0.85 WHR
Waist-to-Hip Ratio Chart
| Category | Men | Women |
|---|---|---|
| Lower Range | Below 0.90 | Below 0.85 |
| Higher Risk Range | 0.90 or higher | 0.85 or higher |
How to Measure Waist and Hips
Use a flexible measuring tape. Measure your waist around the narrowest part of your abdomen or around the belly button area. Measure your hips around the widest part of your hips and buttocks. Keep the tape horizontal and snug, but do not compress the skin.
WHR vs BMI
BMI uses height and weight, while WHR looks at body shape and fat distribution. A person can have a normal BMI but still carry more fat around the waist. For a better picture, use WHR with BMI, waist circumference, body fat percentage, and professional health checks.
Why Your WHR Result Is Only a Screening Tool
WHR does not directly measure internal fat, blood sugar, cholesterol, blood pressure, liver health, fitness level, or overall disease risk. It is useful as a quick home measurement, but it should not replace medical evaluation.

Waist-to-Hip Ratio Calculator FAQs
What is waist-to-hip ratio?
Waist-to-hip ratio is a body measurement that compares waist size to hip size. It is calculated by dividing waist circumference by hip circumference.
How do I calculate waist-to-hip ratio?
Measure your waist and hips using the same unit. Then divide your waist measurement by your hip measurement. For example, an 85 cm waist and 100 cm hips gives a WHR of 0.85.
What is a high waist-to-hip ratio?
Commonly used public-health cutoffs place higher risk around 0.90 or higher for men and 0.85 or higher for women, but personal risk can vary.
Is WHR better than BMI?
WHR and BMI measure different things. BMI compares height and weight, while WHR looks at body fat distribution. Using both can give better context than using one number alone.
Can WHR diagnose disease?
No. WHR is only a screening measurement. It cannot diagnose diabetes, heart disease, obesity, or any medical condition.
