Free Printable Body Mass Index (BMI) Charts

The body mass index, or BMI, is a chart used to estimate the amount of weight on your body. The index usually takes into account a person’s gender, age, height, weight, and other variables to give you insight on what your weight should be. In order to calculate your BMI, you would measure your weight in kilograms and your height in meters. Afterwards, divide your weight by your height. Divide that number by your height again, and that is your BMI. Typically speaking, there are four ranges when reading the BMI.



The BMI defines individuals that are underweight as those whose index is lower than 18.5. Being underweight carries a host of health problems, such as fatigue, fragile bones, and a weakened immune system.

These ranges, of course, vary between each individual. Even so, the BMI is a good way to know whether or not you have a healthy weight, and if you need to make any lifestyle changes associated with it. What’s more, it’s easy to calculate, and oftentimes, a good way to get an estimate as to what you may need. While a simple BMI chart might not encompass everything, it’s an excellent way to help you get started on where you might need to be.
