Your waist-to-hip ratio (WHR) is a simple indicator of health risk related to body fat distribution. Enter your measurements below to see your ratio and risk category based on WHO guidelines.

How It Works
The waist-to-hip ratio is calculated by dividing your waist circumference by your hip circumference: WHR = Waist ÷ Hip. The World Health Organization uses WHR as an indicator of health risk because it reflects how fat is distributed in the body.
People who carry more weight around their waist (apple shape) have a higher risk of heart disease and type 2 diabetes compared to those who carry weight around their hips (pear shape). WHO classifies risk as: Males — Low ≤0.90, Moderate 0.91–1.0, High >1.0; Females — Low ≤0.80, Moderate 0.81–0.85, High >0.85.
Frequently Asked Questions
How do I correctly measure my waist and hips?
Measure your waist at the narrowest point, typically just above the belly button. Measure your hips at the widest point of your buttocks. Use a flexible tape measure, keep it level, and don't pull it too tight. Measure against bare skin for accuracy.
Is waist-to-hip ratio better than BMI?
WHR and BMI measure different things. BMI assesses overall weight relative to height, while WHR evaluates fat distribution. Research suggests WHR may be a better predictor of cardiovascular risk because abdominal fat is more metabolically dangerous. Using both together gives a more complete picture.
What is a healthy waist-to-hip ratio?
According to WHO, a healthy WHR is 0.90 or less for men and 0.80 or less for women. Values above these thresholds indicate increased risk for cardiovascular disease and metabolic conditions.
