What BMI Means

BMI is a number that tells you if your weight is healthy for your height. Doctors use it to check your health. It doesn't measure body fat — but it's a good place to start.

🔢

How to Use It

Enter your height (feet and inches) and your weight (pounds). Tap Calculate. Your BMI and category show up instantly. Try a different weight to see how the number changes.

💡

What to Do Next

Normal weight? Great. Keep it up. Overweight or Obese? Don't panic. BMI is just one number. Talk to your doctor. Small changes help — like walking 15 more minutes a day.
