Waist-to-Hip Ratio Calculator
Calculate WHR and health risk
WHR = waist circumference ÷ hip circumference. Higher ratios indicate more abdominal fat and higher health risk.

What Is Waist-to-Hip Ratio?
Waist-to-hip ratio (WHR) compares your waist circumference to your hip circumference. It indicates where you store body fat — around the waist (apple shape) or hips (pear shape).
WHR = waist circumference ÷ hip circumference
**Health risk categories (WHO)**: - Men: Low risk < 0.90, Moderate 0.90–0.99, High ≥ 1.0 - Women: Low risk < 0.80, Moderate 0.80–0.84, High ≥ 0.85
Higher WHR (more abdominal/visceral fat) is associated with higher risk of heart disease, type 2 diabetes and other metabolic conditions.
**Measurement tips**: Measure waist at the narrowest point (above belly button) and hips at the widest point. Use the same unit for both — inches or centimeters both work.
- WHR = waist ÷ hip
- Unit-independent (inches or cm)
- WHO risk categories by gender
- Higher ratio = more abdominal fat
Worked Example
Example: Female, waist 32 inches, hips 38 inches.
- WHR = 32 ÷ 38 = 0.842 - Women's category: 0.80–0.84 → Moderate risk
If her waist were 36 inches: WHR = 36 ÷ 38 = 0.947 → High risk (≥ 0.85).

Is WHR better than BMI?
They measure different things. BMI measures overall weight relative to height; WHR measures fat distribution. WHR is often considered a better indicator of metabolic risk, especially for people with high muscle mass.
Can I use centimeters?
Yes. WHR is a ratio, so as long as you use the same unit for both waist and hip, the result is the same.
