Healthy-Weight Calculator
Calculate Your Body Mass Index
According to the Centers for Disease Control and Prevention (CDC), measuring your Body Mass Index (BMI) is the most reliable way to calculate a healthy weight range for your height. To calculate your BMI and healthy weight, enter your height and weight below.
Put this information to use:
A BMI of 19-24 is considered normal, while BMIs of 25-29 are defined as overweight. Obesity begins at a BMI of 30, which translates to about 30 extra pounds, depending on your height. These definitions of overweight and obesity were established after several studies examined the BMIs of millions of people and correlated them with rates of illness and death.* BMIs in the normal range are associated with the lowest rates of illness and death, while higher BMIs are associated with progressively higher rates of illness and death.
Even though BMI is very useful, looking at these numbers alone can be somewhat deceptive. The "normal" range in the BMI table covers a lot of ground. A person at the lower end of the spectrum could gain a significant amount of weight, which in itself is a risk factor for disease, and still remain in healthy territory. For example, a 5'6", 130-pound woman with a BMI of 21 could gain 20 pounds and still keep her BMI under 25.
