Finding your healthy weight range

We've all heard it before: maintaining a healthy weight is important. But why does having a healthy weight matter - and how do we find out if what we weigh is considered in a healthy range? A simple way to know if your weight is healthy is to determine your body mass index, or BMI. BMI is the measure of your weight in relation to your height. Use this simple calculation to determine your BMI: BMI = Weight ÷ height in inches ÷ height in inches again × 703*. Or use our BMI calculator. Find your BMI below and see what range you fall into.

BMI ranges

Underweight Less than 18.5
Normal 18.5 to 24.9
Overweight 25 to 29.9
Obese 30 to 39.9
Morbidly obese 40 and greater

When your weight is in normal range, you decrease your risk for heart disease, high blood pressure, type 2 diabetes and certain types of cancer.

*For adults only; children's BMI is calculated differently. Talk to your child's health care provider if you are concerned about your child's weight.
