How do I measure correctly?

Measure at the narrowest point of your waist (usually just above the navel) and the widest point of your hips, both while standing relaxed.

Which number is the danger zone?

A waist-to-hip ratio over 0.90 for men or 0.85 for women is classified as high risk by WHO.

Nothing you enter leaves your device

All of the work happens inside your browser. Whatever you type is never packaged up and sent to a server, and no request this page makes carries it.

That makes it safe for contract amounts, personal details and internal documents you would rather not hand to a third party — close the tab and it is gone.

What this tool does not do

Waist to Hip Ratio Calculator only does what a browser can do on its own — it talks to no backend service. So it keeps no history for you and syncs nothing across devices; if you need a record, copy or download the result.

It is also not a substitute for professional judgement. For legal, medical or tax decisions, treat the output as a starting point rather than a final answer.
