BMI is a screening tool, not a diagnosis - it does not account for muscle mass, bone density or body composition. Talk to a health professional before making decisions based on this number.
About this tool
IconVault's BMI Calculator computes your body mass index from height and weight in metric (cm/kg) or imperial (in/lb) units, and shows the result on a color-coded gauge across the four standard WHO category bands: Underweight, Normal, Overweight and Obese. It also tells you the healthy weight range for your height, and you can copy the result with one click.
Everything is free and runs fully in your browser: your numbers are never sent anywhere. One honest note: BMI is a screening tool, not medical advice. It does not account for muscle mass or body composition, so talk to a health professional before acting on the number.
