Simple Measurement
You only need a flexible measuring tape and two body measurements to calculate your ratio.

Waist to Hip Ratio Calculator
Calculate your waist-to-hip ratio in seconds and get a simple interpretation of your body fat distribution using your waist and hip measurements.
Calculate Your WHR
Enter both measurements using the same unit.
What Is Waist-to-Hip Ratio?
Waist-to-hip ratio, commonly shortened to WHR, compares the circumference of your waist with the circumference of your hips.
Body Fat Distribution
WHR provides general information about how body weight may be distributed around the waist and hips.
Screening Tool
The result can support a broader health assessment, but it should not be treated as a diagnosis.
How the Waist to Hip Ratio Calculator Works
Follow these steps to get a consistent and useful waist-to-hip ratio result.
Measure your waist
Wrap a flexible tape around your waist between the lowest rib and the top of the hip bone. Keep the tape level and avoid pulling it too tightly.
Measure your hips
Measure around the widest part of your hips and buttocks while keeping the tape horizontal.
Use the same unit
Enter both values in centimetres or both values in inches. Do not mix different measurement units.
Calculate and review
The calculator divides your waist circumference by your hip circumference and displays the resulting ratio.
Waist-to-Hip Ratio Formula
WHR = Waist Circumference ÷ Hip Circumference
Waist-to-Hip Ratio Reference Guide
The calculator uses commonly cited adult screening cutoffs. Individual risk can vary based on age, ethnicity, health history, pregnancy, and other factors.
| Reference category | Ratio | General interpretation |
|---|---|---|
| Male | 0.90 or lower | Within reference cutoff |
| Male | Above 0.90 | Above reference cutoff |
| Female | 0.85 or lower | Within reference cutoff |
| Female | Above 0.85 | Above reference cutoff |
How to Get an Accurate Measurement
Small differences in tape position can change your result, so use the same technique each time.
- Measure over bare skin or thin, close-fitting clothing.
- Stand upright with your feet together and body relaxed.
- Keep the measuring tape level with the floor.
- Let the tape touch the skin without compressing it.
- Take the waist measurement after a normal exhalation.
- Repeat each measurement and use the average when the readings differ.
Understanding Your WHR Result
A waist-to-hip ratio is one of several measurements that may be used to understand body composition and abdominal fat distribution. A higher result means your waist is larger in relation to your hips.
WHR does not measure total body fat and cannot explain why a measurement is higher or lower. Body shape, muscle development, age, genetics, pregnancy, medical conditions, and measurement technique can all affect the result.
Should WHR replace BMI?
No single measurement provides a complete picture of health. WHR, BMI, waist circumference, blood pressure, laboratory results, medical history, and lifestyle factors may provide different types of information.
When should you speak to a healthcare professional?
Consider professional advice when you are concerned about your result, have experienced a significant unexplained change in body measurements, or have risk factors such as high blood pressure, diabetes, or a family history of cardiovascular disease.
Frequently Asked Questions
Common questions about calculating and understanding waist-to-hip ratio.
Divide your waist circumference by your hip circumference. For example, an 80 cm waist divided by 100 cm hips produces a waist-to-hip ratio of 0.80.
Yes. You can use inches or centimetres because the result is a ratio. Both measurements must use the same unit.
Place the tape around the midpoint between your lowest rib and the top of your hip bone. Keep it level and take the measurement after a normal exhalation.
Measure around the widest part of your hips and buttocks. Keep the tape horizontal without pulling it tightly into the skin.
Common adult screening references describe a ratio above 0.90 for men or above 0.85 for women as being above the general reference cutoff. Individual interpretation may vary.
No. The calculator is an educational screening tool. A healthcare professional should assess your overall health and individual risk factors.
There is usually no benefit in measuring it every day. When tracking changes, use the same technique and similar conditions every few weeks.
