Use the Waist-to-Height Ratio calculator

The Waist-to-Height Ratio calculator is a tool that provides an assessment of your health, by dividing your waist circumference by your height to estimate how much fat is distributed around your stomach. While Body Mass Index (If you haven’t checked your BMI yet, do it now) gives a general indication of obesity, the Waist-to-Height Ratio calculator can be used to estimate your risk of heart disease and other obesity related risk factors. The Waist-to-Height Ratio calculator can therefore be used to gain a more holistic understanding of your health.The tool is designed to support people living with obesity to focus on reducing the risk of heart disease as part of an overall approach to improving health.
