BMI Calculator
Enter height and weight (metric or imperial) for your BMI, category, and healthy range.
About this tool
Body Mass Index is a quick screening number based on your height and weight: weight in kilograms divided by height in metres squared. This calculator supports both metric and imperial inputs and instantly tells you which standard category your result falls into.
It also shows the healthy weight range for your height, which is often more useful than the single BMI number — especially if you are tracking progress over time.
How to use
- Switch between Metric (cm/kg) and Imperial (ft/lb) if needed.
- Enter your height and weight.
- Read your BMI, category, and healthy weight range.
