Calculate Your Waist to Hip Ratio
Your waist and hip measurements can tell you something about how your body measurements relate to each other.
The Waist to Hip Ratio, often shortened to WHR, compares the circumference of your waist with the circumference of your hips.
Our calculator makes this calculation simple. Enter your waist and hip measurements, use the same unit for both and check your result.
You don’t need to work out the ratio yourself. Just make sure your measurements are entered correctly.
This tool is useful for people who want to understand their body proportions or keep a record of their measurements.
Waist to Hip Ratio Calculator
Calculate waist-to-hip ratio from two circumference measurements. Health-risk interpretation depends on sex, age and clinical context.
How to Calculate Waist to Hip Ratio
The calculation is straightforward:
Waist to Hip Ratio = Waist Circumference ÷ Hip Circumference
For example:
- Waist measurement: 30 inches
- Hip measurement: 40 inches
- Calculation: 30 ÷ 40
- Result: 0.75
This means the waist measurement is 75% of the hip measurement.
The example is only for explaining the calculation. Your result will depend on your own measurements.
How to Measure Your Waist
Stand naturally and keep your stomach relaxed.
Place a flexible measuring tape around your waist at the measurement point specified by the method you are following. Keep the tape level and avoid pulling it too tightly.
How to Measure Your Hips
Stand with your feet together and measure around the widest part of your hips and buttocks.
Keep the tape level all the way around your body.
For a meaningful comparison, use the same measurement method every time.
Why Do People Check Their Waist to Hip Ratio?
WHR is used to describe how waist circumference compares with hip circumference.
It is also used in some health assessments as one of several indicators related to fat distribution.
However, a single ratio cannot tell you everything about your health. Age, medical history and other measurements may also matter.
Frequently Asked Questions
What is the waist to hip ratio formula?
Divide your waist circumference by your hip circumference. Both measurements should use the same unit.
Can I use inches instead of centimetres?
Yes. You can use either unit as long as both measurements are in the same unit.
What does WHR stand for?
WHR stands for Waist to Hip Ratio.
Is waist to hip ratio the same as BMI?
No. BMI compares weight and height, while WHR compares waist and hip circumference.
Can men and women use this calculator?
Yes. It can be used by adults of either sex to calculate the ratio. Interpretation of health-related thresholds may differ.
Is a lower waist to hip ratio always better?
Not necessarily. WHR is only one measurement and should not be used alone to judge someone’s health.
