What Is a Normal BMI (Body Mass Index)?
Body Mass Index (BMI) is an estimate of your body fat level based on your height and weight. A high BMI weight category indicates the potential for health problems.
How to Determine Your BMI
Your BMI estimates how much you should weigh, based on your height. Here are the steps to calculate it:
- Multiply your weight in pounds by 703.
- Divide that answer by your height in inches.
- Divide that answer by your height in inches again
For your convenience the Centers for Disease Control (CDC) has BMI calculators for both adults:
