Waist Ratio Calculator

Waist-to-hip and waist-to-height ratios — the two numbers that beat BMI for belly fat.

Waist-to-hip ratio (WHR)0.88Lower risk range (men)
Waist-to-height ratio0.49Healthy — waist under half your height
Waist target (half your height)≤ 86 cmThe simple rule: keep your waist below half your height

For men, a WHR under 0.90 is the lower-risk range in WHO references; waist-to-height under 0.5 is the widely used healthy cut-off. Belly (visceral) fat drives most of the risk these ratios flag, and it responds to the basics: a modest calorie deficit, daily steps, sleep and strength training.

General information for healthy adults — not medical advice. If you have a medical condition, are on medication, or anything feels off, talk to a doctor before acting on numbers from any calculator.
