FileSenixWhen you visit the doctor for a normal checkup, the nurse always measures exactly how tall you are and exactly how much you weigh.
They use these two numbers to figure out your BMI, which stands for Body Mass Index. It sounds like a big fancy word, but it is actually very simple.
Your BMI is just a special number that helps doctors guess if your weight is perfectly healthy for someone of your exact height. It is a great way to check on your body.
If the number is too high or too low, the doctor might give you some helpful tips on eating better food or playing more sports to get healthy.
You absolutely do not have to wait for your next doctor visit to find out your secret number. You can easily check it right this second with our free BMI Calculator tool.
Just type in how tall you are and how much you weigh. The calculator does the math instantly and tells you if your number falls into the healthy, happy zone!
