Is waist to height more accurate than BMI?

It is more directly tied to visceral fat — the type that wraps organs and drives insulin resistance — so yes, for cardiometabolic risk it tends to track better than BMI.

The rule of thumb used by NHS: keep your waist less than half your height. Anything past that is a flag for higher cardiometabolic risk.

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 Height 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.
