It's a quick way for anyone to check the health risks tied to body fat distribution. Everything is calculated instantly in your browser, so your measurements are never sent to a server.

FAQ
- How do I measure my waist and hips correctly?
- Stand up straight and measure your waist at its narrowest point, just above the navel, and your hips at their widest point.
- What standard do the risk levels follow?
- They follow World Health Organization (WHO) guidelines, which set the low-risk threshold at 0.90 for men and 0.80 for women.
- Does this ratio still make sense for pregnant women or people with a very muscular midsection?
- Not really — pregnancy and a heavily muscled abdomen can skew the number even when fat distribution is healthy, so treat the WHR result as a rough reference and cross-check with something like a body composition test in those cases.
