BMI Calculator
Enter your height and weight to estimate your body mass index.
How this works
BMI is weight in kilograms divided by height in meters, squared. It's a quick screening number, not a diagnosis -- it doesn't account for muscle mass, bone density, age, or sex, so talk to a doctor for a fuller picture of your health.
- Under 18.5: underweight
- 18.5 – 24.9: normal weight
- 25 – 29.9: overweight
- 30 and above: obese
