BMI Calculator

Enter your height in centimetres and your weight in kilograms. The tool instantly computes BMI using the standard formula and places the result into the usual adult categories. Use metric units consistently for the most reliable comparison with published charts.

If you are tracking progress over time, measure weight at the same time of day and under similar conditions. BMI is only one signal: waist size, blood pressure, blood tests, activity level and diet quality all matter for health outcomes.

BMI was designed for epidemiology, not as a standalone diagnosis. People with higher muscle mass, fluid retention or certain medical conditions may have a BMI that does not reflect body fat. Conversely, some people within the “healthy” range may still carry excess visceral fat.

If you are concerned about weight, metabolism or chronic conditions, speak with a qualified healthcare professional. They can interpret BMI alongside other tests and your personal history.
