WHtR.org is a free set of evidence-based health calculators. Start with the waist-to-height ratio — a simple measure that compares your waist to your height and predicts cardiovascular and metabolic risk more accurately than BMI. Enter two measurements for instant results, with no sign-up and nothing stored.
