Waist to Hip Ratio (WHR) Calculator
Enter your measurements to compute your WHR instantly.
Edit WHR to back-solve for the other measurement. Which one updates depends on your last edited field or which value is present.
How the Waist-Hip Ratio Calculator Works
- Choose Units: Use centimeters or inches for both waist and hip inputs. We convert internally to centimeters.
- Measure Correctly: Measure your natural waist (narrowest point between ribs and navel) and the widest part of your hips/buttocks. Keep the tape level and snug, not tight.
- Enter Values: Type both numbers above. WHR is computed as
W / H. - Interpret: Compare the result with the general guidance shown at right. Consult a clinician for personalized advice.
About Waist-Hip Ratio
Why is waist-hip ratio important?
WHR is a simple indicator of fat distribution. A higher WHR often correlates with greater visceral fat and has been associated with elevated risk of cardiometabolic diseases. Unlike BMI, which only considers weight and height, WHR highlights where fat is carried.
How should I measure waist and hips?
Measure your waist at the narrowest point between the lower rib and navel after a normal exhale. Measure hips at the widest part around the buttocks. Keep the tape parallel to the floor; take measurements on bare skin or thin clothing.
How do I calculate the waist to hip ratio?
Use the formula WHR = Waist / Hip. For example, 80 cm waist and 100 cm hips gives 0.80.
How does the waist to hip ratio calculator work?

What is a good waist to hip ratio?
Lower ratios generally indicate lower health risk. Broadly, WHR below ~0.80 (female) or ~0.90 (male) is often considered lower risk. Always consult healthcare providers for individual targets.
What is normal waist to hip ratio?
Definitions vary by guideline and population. Many references consider 0.80–0.85 (female) and 0.90–1.00 (male) as intermediate ranges.
How to reduce waist-hip ratio?
Lifestyle approaches like balanced nutrition, resistance + aerobic training, adequate sleep, and stress management may reduce central adiposity and improve WHR. Seek professional guidance for safe plans.
What is the average hip to waist ratio for women?
Population averages differ by region and age. A commonly cited target for lower risk in women is below ~0.80, but consult local references and clinicians for context.
