BMI Calculator

BMI stands for “body mass index,” which is a metric for measuring body fat based on height and weight. While BMI is a popular tool, it’s not perfect. BMI does not differentiate between body fat and muscle mass. 

We recommend attending one of our free seminars to learn more about options for losing weight.

Rather than relying only on the bathroom scale to tell you if you're overweight, experts say you should also know your body mass index (BMI). BMI takes into account not just your weight, but also your height to indicate body fat. The goal for most people is a BMI that's over 18 and under 25. This tool is for adults. BMIs for children and teens use age, plus height and weight.
