Understanding Your Result

One number

Many ways to be well

Body Mass Index (BMI) is a simple, widely used screening calculation based on your height and weight. While it provides a helpful starting point for assessing whether your weight is within a healthy range, it does not directly measure body fat percentage or how fat is distributed across your body.

Because muscle tissue is denser than fat, individuals with high muscle mass—such as athletes or strength trainers—may record a higher BMI without carrying excess body fat. Similarly, age, sex, and natural body frame differences can influence how your result should be interpreted.

Support for your next step

Wellbeing, made practical

For a more complete picture of your overall health, healthcare professionals often look at BMI alongside other indicators such as waist-to-height ratio, blood pressure, cholesterol levels, and lifestyle habits including physical activity and nutrition.

Please note that standard adult BMI ranges are intended for adults aged 18 and over and are not suitable for children, teenagers, or women who are pregnant. If you have questions about your weight or health goals, speak with a GP, pharmacist, or registered dietitian for tailored advice.
