About this tool
Divide your waist by your height and you get a ratio that many people find easier to picture than weight alone. Values near 0.5 are often used as a rough guide, with higher values sitting in a higher band. Treat the result as a general prompt to look at overall habits, not as a medical verdict.
Frequently asked questions
Do I measure waist at the belly button?
Measure around the middle, roughly at belly-button level, with the tape level and relaxed.
Why use height at all?
Height gives the waist a scale, so the same waist means something different for a shorter and a taller person.
