Free Waist-to-Hip Ratio Calculator
Check your waist-to-hip ratio and health band.
What is the Waist-to-Hip Ratio Calculator?
Where you carry weight matters as much as how much you carry. The waist-to-hip ratio compares those two measurements as a simple indicator of body-fat distribution, which research links to health risk more closely than weight alone.
This calculator works out your ratio from a waist and hip measurement and shows which general health band it falls into.
Last updated: Aug 12, 2026
What does this tool do?
You enter your waist and hip circumference, and the tool divides waist by hip to give the ratio.
It then compares that ratio against widely used thresholds, which differ by sex, and shows whether it sits in a lower, moderate or higher risk band.
Key features

Health band
Compares against sex-specific thresholds.
Any units
Use inches or centimeters, as long as both match.

Example
Common use cases
- Health-conscious people — Track a meaningful body metric.
- Dieters — Monitor fat distribution over time.
- Fitness enthusiasts — Complement weight and BMI.
- Coaches — Give clients an extra data point.
- Nurses — Do a quick screening measurement.
- Students — Learn how WHR is calculated.
- Older adults — Watch a risk-linked measure.
- Anyone measuring progress — Look beyond the scale.
Benefits
- It reflects fat distribution, not just total weight.
- It's a quick, tape-measure-only check.
- It shows a health band, not just a number.
- Your measurements stay on your device.
Tips
- Measure the waist at its narrowest point and the hips at the widest.
- Use the same units for both measurements.
- Measure over bare skin or light clothing, without pulling the tape tight.
- Take each measurement twice and average for consistency.
- Lower ratios generally indicate lower risk.
- Track the trend over time rather than one reading.
- WHR complements BMI and body fat — use them together.
- It's a general screening guide, not a diagnosis.
Common mistakes to avoid
Measuring the wrong spots
Fix: Waist at the narrowest point, hips at the widest — not at the belt line.
Mixing units
Fix: Use the same units for waist and hip; the ratio is unitless.
Pulling the tape tight
Fix: Keep it snug but not compressing the skin.
Treating it as a diagnosis
Fix: It's a screening indicator — discuss health concerns with a professional.

Measure your waist at the narrowest point and your hips at the widest, using the same units.
Either inches or centimeters — the ratio is unitless as long as both use the same unit.
It captures fat distribution, which BMI misses, so they work best together rather than one replacing the other.
No. It's a general screening guide; consult a professional about health concerns.
No. Everything is calculated in your browser.
Conclusion
Waist-to-hip ratio adds a risk-linked dimension the scale can't show. Track it alongside the BMI and body-fat calculators for a rounded view of your health.
