Waist to Height Ratio Calculator
A simple rule: keep your waist to less than half your height. Divide your waist by your height to see your ratio and its band.
How we got it
Waist divided by height. Bands from NICE (UK, 2022): under 0.5 healthy, 0.5 to 0.59 increased, 0.6 or more high. Tape error is about plus or minus 0.02.
