BMI calculator
Body mass index (BMI) is a quick screening number based on your height and weight. It doesn't measure body fat or health on its own, but it's a common starting point for a conversation with a physician.
Please check your height and weight.

What BMI can and can't tell you
- BMI is a screening tool, not a diagnosis. It doesn't measure body fat, muscle or where weight is carried.
- It can read high for muscular or very active people, and it may not reflect health the same way across ages, sexes and backgrounds.
- These adult ranges are for people 20 and older. They don't apply during pregnancy or to children and teens.
Have questions about your weight or health? A licensed physician can look at the whole picture: your history, your goals and your real life. Your BMI alone doesn't decide whether any treatment is right for you.
