Body Mass Index Calculator
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 uses your weight and height to show if you may have too much 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.
