Enter values above and click Calculate — results will appear here with the formula explained.
Waist-to-hip ratio divides waist circumference by hip circumference, both measured in the same unit, and sorts the result against World Health Organization screening thresholds: above 0.90 for men and 0.85 for women correlates with higher visceral adiposity and metabolic risk in population data. It captures distribution where BMI captures mass — a person with healthy BMI can still carry risky central deposition, and conversely a muscular build can score high on BMI but normal on WHR — so the calculator presents both for context rather than judgment.
WHR is screening, not diagnosis. Measurement protocol drives the number: waist at the midpoint between the lowest rib and iliac crest after gentle exhalation, hips at the maximum gluteal protrusion, tape horizontal without compression. Track the same protocol and time of day across weeks; day-to-day water and meal variability typically swings the ratio by 0.02 or more.

Waist-to-hip ratio divides waist circumference by hip circumference, both measured in the same unit, and sorts the result against World Health Organization screening thresholds: above 0.90 for men and 0.85 for women correlates with higher visceral adiposity and metabolic risk in population data. It captures distribution where BMI captures mass — a person with healthy BMI can still carry risky central deposition, and conversely a muscular build can score high on BMI but normal on WHR — so the calculator presents both for context rather than judgment. Formula: WHR = waist / hip; Risk: M >0.90, F >0.85 high
Waist to Hip Ratio Calculator: Calculate waist-to-hip ratio (WHR) from waist and hip measurements — see ratio, health risk category and ideal range. Formula: WHR = waist / hip. Example: With 85cm waist, 100cm hip: WHR 0.

With 85cm waist, 100cm hip: WHR 0.85. For male, moderate (0.90 threshold not met), for female at threshold.
