About this BMI Calculator
Body Mass Index (BMI) is the standard screening measure that relates your weight to your height. Doctors and health organisations worldwide use the same cut-offs: below 18.5 is underweight, 18.5โ24.9 is the healthy range, 25โ29.9 is overweight, and 30 or above is obese.
Enter your height and weight to get your BMI instantly, together with the healthy weight range for your height. The calculation never leaves your device, so it is completely private. Note that BMI is a screening tool, not a diagnosis โ athletes with high muscle mass and older adults should interpret it alongside professional advice.
