Waist-to-Hip Ratio Calculator
Waist-to-hip ratio (WHR) describes how body fat is distributed. Central (android) fat compared with hip (gynoid) fat is linked to cardiovascular disease, type 2 diabetes, and metabolic syndrome risk.
The DiyetisyenPRO WHR calculator uses waist and hip circumferences, compares your result to WHO reference cutoffs by sex, and offers personalized guidance.
How WHR Is Calculated
Waist circumference ÷ hip circumference. Measure in centimeters; results are typically interpreted between about 0.70 and 1.00.
Risk Categories (WHO References)
- Women: Below 0.80 low risk; 0.80–0.85 moderate; above 0.85 high.
- Men: Below 0.90 low; 0.90–0.95 moderate; above 0.95 high.
Measurement Tips
- Waist: Standing comfortably, at navel level after normal exhale.
- Hip: At the widest point of the buttocks, tape parallel to the floor.
- Tape: Use a non-stretch tape; do not compress skin.
- Repeat: Two measures under the same conditions, then average.
What the DiyetisyenPRO Tool Provides
- Instant WHR: From waist and hip inputs.
- Sex-specific risk band: Low, moderate, or high vs WHO thresholds.
- Visual scale: Where your result sits on the healthy range.
- Personal tips: Nutrition and lifestyle pointers matched to risk level.
When to See a Dietitian
If you are in moderate or high risk, your waist is rising over time, or you have weight-loss goals, a personalized nutrition plan with a dietitian supports sustainable outcomes.
Frequently asked questions
Waist-to-hip ratio (WHR) is waist circumference divided by hip circumference. It helps assess fat distribution, especially central (abdominal) fat.
Use waist (cm) ÷ hip (cm). For example, 78 cm waist and 98 cm hip gives a ratio of 0.80.
WHO references: below 0.80 for women and 0.90 for men is low risk. Above 0.85 (women) or 0.95 (men) is considered high risk.
Standing, after exhaling, measure horizontally at navel level with a non-stretch tape. Do not compress the skin.
Measure at the widest point of the hips, keeping the tape parallel to the floor.
BMI relates total weight to height. WHR shows where fat is stored. Central fat is more strongly linked to cardiovascular risk.
