Waist-to-Height Ratio
The waist-to-height ratio (WHtR) is increasingly recognised as a better predictor of health risks than BMI. The simple rule: keep your waist circumference to less than half your height. Enter your measurements to see your ratio, risk category, and how it compares to BMI-based assessments.
Used for context only; the 0.5 threshold applies universally.
Why Waist-to-Height Ratio Is Useful
The waist-to-height ratio is a simple, inexpensive screening tool that has been validated across different ages, sexes, and ethnic groups. A 2012 meta-analysis of over 300,000 adults found that WHtR was a better predictor of cardiovascular risk, diabetes, and mortality than BMI.
The beauty of this measure is its simplicity: the 0.5 boundary works for adults and children alike. If your waist is less than half your height, your risk is generally low. If it exceeds half your height, the risk rises significantly.
Unlike BMI, WHtR captures abdominal fat distribution, which is the most metabolically dangerous type of fat. Visceral fat surrounding your organs releases inflammatory chemicals and hormones that increase your risk of heart disease, insulin resistance, and certain cancers.
