Calculate your Body Mass Index (BMI) to assess your weight status and get insights about your health indicators.
Our BMI calculator makes it a piece of cake for you to find your number. However, please remember that BMI is a rough estimation. The result can be somewhat misleading for individuals who are well-muscled (such as bodybuilders) or for those who have lost a significant amount of muscle (such as the elderly).
If you are unsure whether or not you fall within the "normal" range of muscle mass, please consider using one of our more specialized calculators. If you want to determine your body composition that adjusts for skeletal mass, you may want to use our body frame size calculator. Additionally, check out our skinfold body fat calculator to figure out what percentage of your body is fat.
There are five basic ranges within the BMI scale:
The BMI Prime is a nifty modification to our own BMI calculator. It's a decimal number where 1.0 = the upper limit to the "normal BMI" range. It's a super easy way to see if you're overweight or not. If your BMI Prime is more than 1, then you've got some weight to lose.
Simply enter your height and weight, select your gender, and our calculator will provide you with your BMI value and category. The tool also calculates your BMI Prime for additional insight into your weight status.
