Waist-to-Hip Ratio Formula
Waist-to-Hip Ratio = Waist Circumference ÷ Hip Circumference
Waist-to-Hip Ratio (WHR) measures body fat distribution by comparing waist size to hip size. Higher ratios may indicate increased health risks related to abdominal fat accumulation.
Example Calculation
Input: Waist: 80 cm, Hip: 100 cm
Output: WHR = 0.80

Questions about this calculator
Waist-to-Hip Ratio (WHR) compares your waist measurement to your hip measurement and helps assess body fat distribution.
WHR can indicate whether excess body fat is concentrated around the abdomen, which may be associated with increased health risks.
Generally, a WHR below 0.90 for men and below 0.85 for women is considered lower risk.
WHR and BMI measure different aspects of health. WHR focuses on fat distribution, while BMI focuses on weight relative to height.
Regular exercise, healthy eating, and weight management can help reduce waist circumference and improve WHR.
Visceral fat deposits deep within the abdominal cavity around vital organs, secreting inflammatory cytokines and fatty acids into circulation. This significantly increases insulin resistance and cardiovascular strain compared to subcutaneous fat stored beneath the skin.
How to measure waist-to-hip ratio
Measure the waist and hips with the same tape and unit. Keep the tape level and snug without compressing the skin. Measure the waist at the location specified by the health guidance you follow and the hips around their widest point.
Formula and example
WHR = waist circumference ÷ hip circumference. A waist of 80 cm and hips of 100 cm gives 0.80. Because the units cancel, the same ratio results when both measurements are entered in inches.
Do not use the ratio as a diagnosis
Risk thresholds vary by sex, population, age, and clinical guideline. Measurement technique, pregnancy, body shape, and medical conditions can also affect interpretation. Discuss health concerns with a qualified healthcare professional rather than relying on this ratio alone.
