BMI calculator

What is a Body Mass Index (or BMI) calculator for? In short, this is an indication as to whether you are overweight, obese, underweight or right on target weight. As great at the body mass index (or BMI) sounds, unfortunately it does over-estimate results for people who are muscular or athletic in build making them seem (according to the charts) as though they are overweight.

So what about the results? In general, women believe they look their best at resulting values of between 20 to 22, Men, usually being satisfied with between 23 and 25. In addition, if your result is between 17 to 22, your life expectancy tends to be slightly longer than average.

Don't worry too much about the results from the calculator, it is not perfect. If the description of your body seems wrong, trust your own judgment as a healthy mental attitude is as important in most cases as overall physical fitness.


Between 23 and 25, you are not considered overweight by most people.

26 or more is not good, but then you probably knew that already.
