BioTrainer Tools - BMI Calculator

Body Mass Index (BMI) can be used to indicate if you are overweight, obese, underweight, or normal. It will, however, overestimate fatness in people who are muscular or atheletic. Because of these problems, this body mass index calculator shows extra statistics to help you be informed and judge your own body compared to others of the same height and age.

Calculate your Body Mass Index and compare yourself to friends with a similar age and height.

Enter your age, then re-calculate:









If at 50th percentile, you are close to average weight.
At 90th percentile, your weight is greater than 90% of others.
At 20th percentile, then 80% of others weigh more than you.

What do the results mean?

Women tend to believe they look their best at values between 20 to 22 and men are usually satisfied with a BMI of 23 to 25. If your BMI is between 17 to 22, your life expectancy is longer than average. You don't need to lose weight.

If your BMI is between 23 and 25, you are not considered overweight by most people. But if your BMI is 26 or more, that's not good. But you knew that already.

Most of all, Relax! It’s not healthy to be anxious over a less-than-perfect body image. This calculator is just a guide. If this description of your body doesn’t seem right to you, don’t worry about it! Trust your own instincts.
