BMI calculator
Calculate your body mass index and see a healthy weight range for your height.
How it works
BMI is weight in kilograms divided by height in meters squared. Categories follow the World Health Organization: under 18.5 underweight, 18.5 to 24.9 healthy, 25 to 29.9 overweight, and 30 or more obesity.
BMI is a screening tool, not a diagnosis.
