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 takes into

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.
