Waist to Height Ratio Formula
The following formula can be used to calculate the ratio of your waist circumference to height.
W:H = W / H
- Where W is your waist circumference
- H is your height
To calculate a waist to height ratio, divide the waist circumference by the height.
NHS guidance is often summarized as: aim for a waist size less than half your height (WHtR under 0.5) for most adults. For details (including how to measure), check the NHS website guidance on waist-to-height ratio.

FAQ
Waist-to-height ratio (WHtR) is a screening measure that can help estimate risk related to central fat distribution (e.g., cardiometabolic risk). It’s one indicator and should be interpreted alongside other factors, and results can vary for different body types (including athletes) and across age groups.
