What is a healthy waist-to-hip ratio?

For men, below about 0.90 is considered low risk. For women, below about 0.80. Higher ratios point to more fat stored around the middle, which carries greater health risk.

How is this different from waist-to-height ratio?

Both look at central fat. Waist-to-hip compares your middle to your hips, capturing body shape, while waist-to-height compares your middle to your height. They are complementary quick checks.

The science

Where you carry fat matters as much as how much you carry. Waist-to-hip ratio compares your waist to your hips, and a higher ratio, meaning more fat around the middle, is linked with greater health risk. It takes two measurements and a moment, and the World Health Organization uses it as a recognized marker.
