Waist-to-Height Ratio Calculator (WHtR)

The waist-to-height ratio calculator (WHtR) is an efficient way to calculate the distribution of body fat. You can use this tool to help you identify whether someone is extremely slim, slim, healthy, overweight, very overweight, or obese, based on your waist circumference and height.

The ratio is determined by dividing the waist circumference with the height, both measured in the same units.

How to measure the circumference of your waist. Use a tape measure. Measure all the way around your body, while keeping it level with your belly button.
