Understanding your result
How it works
Waist-to-height ratio = waist ÷ height (same units)
Carrying weight around the middle is a stronger risk signal than overall weight. The healthy target is below 0.5 — your waist under half your height. 0.5–0.6 is raised risk; above 0.6 is high. It also shows your waist-to-hip ratio (raised above 0.90 for men, 0.85 for women).
⚕️ A screening indicator only, not a diagnosis. Measure your waist at the midpoint between your lowest rib and the top of your hip bone, after breathing out.
Questions
What is a healthy waist-to-height ratio?
Below 0.5 for most adults — keep your waist to less than half your height. 0.5–0.6 signals raised risk; above 0.6 is high.
Is it better than BMI?
It often flags central-fat risk that BMI misses, and needs no weight scale — many clinicians use both together.
