What does this tool do?
Waist-to-hip ratio compares belly fat with hip circumference and has different screening cutoffs for men and women. This calculator returns the ratio and the corresponding band from World Health Organization guidance.
The Formula
Waist-to-hip ratio = Waist circumference ÷ Hip circumferenceFrequently Asked Questions
What ratio is considered healthy?
WHO uses about 0.90 for men and 0.85 for women as increased-risk thresholds. Lower values are generally associated with lower risk.
Is waist-to-hip ratio better than BMI?
They answer different questions. WHR reflects fat distribution, while BMI reflects weight relative to height. Using both with other health measures gives a fuller picture.
