Frequently asked
How do I measure my waist?
Stand relaxed and measure around your natural waist near the navel — not over loose clothing, and without pulling the tape tight.
Why use WHtR instead of BMI?
WHtR adds shape information BMI misses. Many people find it a more intuitive single number, though it isn't a diagnosis.
What's a 'healthy' range?
A widely cited guideline is to keep WHtR under 0.5 for adults. Like any single number, it's a screening tool, not a verdict.
Does it work for everyone?
It's a rough screen for adults. It isn't validated for children, pregnant people, or very tall/short outliers.
