How to calculate your body mass index (BMI)
If you are trying to figure out if you’re overweight, calculating your body mass index (BMI) is a good baseline to start with. BMI is a common screening tool that measures body fat, and excess body fat is a defining characteristic of being overweight or obese.
Though BMI is not a direct measure of body fat, research has shown that BMI does correlate to direct measures of body fat.
BMI measures body fat based on a person’s height and weight and is easy to calculate. To calculate your BMI, you’ll need to:
- Divide your weight in pounds by your height in inches squared.
- Multiply the result by 703.
The Body Mass Index Scale
Once you have calculated your BMI, refer to the categories below to determine whether you are overweight.
- A BMI between 18.5 and 24.9 is considered within the normal, healthy range.
- A BMI between 25 and 29.9 is considered overweight.
- A BMI of 30 or more is considered obese.
- A BMI of 40 or more is considered extremely obese.
Remember: This number should be used as a starting point because BMI is a screening tool, not a diagnostic tool. Since it doesn’t take other important information into account, such as body composition and lifestyle, it’s best to have a medical professional perform additional assessments to determine if your weight is unhealthy.
