Calculate Your BMI

According to the NIH, BMI is broken into several categories to help you understand whether you may be facing health risks related to your weight. BMI alone cannot predict your health risks and indicate whether you are living a healthy lifestyle, but it is a tool used by physicians to assess your overall health.

• Underweight: Below 18.5
• Normal Weight: 18.5 to 24.9
• Overweight: 25 to 29.9
• Obese: 30+
• Extremely Obese: 40+

Use Your Calculator

There are quite a few calculators out there to easily help you determine your BMI, but you can also calculate yourself with a couple of simple equations:

• Multiply your weight in pounds by 703.
• Divide that answer by your height in inches.
• Divide that answer by your height in inches again.
