Waist-to-Hip Ratio Calculator
Calculate WHR and body fat distribution risk category.
About this tool
Waist-to-hip ratio (WHR) compares waist circumference to hip circumference, and is used as an indicator of body fat distribution \u2014 research has linked a higher WHR (more fat around the waist relative to the hips) to greater cardiovascular risk than overall body weight alone.
Key Features
- Sex-specific risk categories, per WHO reference ranges
- Simple ratio from two measurements
- No scale or BMI needed
How to Use
- Select your sex.
- Measure and enter your waist circumference at its narrowest point.
- Measure and enter your hip circumference at its widest point.
- Click Calculate WHR.
Benefits
- Track body fat distribution independent of total weight
- Use alongside BMI for a fuller picture of health risk
- Simple, repeatable measurement with just a tape measure
Frequently Asked Questions
BMI doesn't distinguish where fat is stored, but fat carried around the waist (an 'apple' shape) is associated with higher cardiovascular and metabolic risk than fat carried around the hips (a 'pear' shape), even at the same BMI \u2014 WHR captures that distribution.
Measure your waist at its narrowest point, usually just above the belly button, and your hips at their widest point around the buttocks \u2014 keep the tape snug but not compressing the skin.
