Free BMI Calculator
Our FREE Body Mass Index (BMI) calculator is based on the standard BMI measurement that calculates the percentage of body fat based on height and weight and it works for both men and women.
Why Calculate Your BMI
Maintaining a healthy body weight is very important to help you avoid serious health problems such as heart disease, high blood pressure, coronary artery disease, coronary vascular disease, heart attack, stroke, high blood cholesterol, type 2 diabetes and cancer.
In women, being overweight contributes to an increased risk for a variety of cancers including breast cancer, colon, gallbladder, and uterus.
One way of checking if YOU are at a healthy weight is to know your Body Mass Index (BMI).
The BMI Calculator can be used to indicate if you are overweight, obese, underweight or normal. It is easy to use. It takes seconds to input your information needed to calculate your BMI.
See below how to interpret your results before you calculate your BMI.
18.5 or less is underweight
18.5 to 24.99 is normal weight
25 to 29.99 is overweight
30 to 34.99 is obese (class 1 – low risk)
35 to 39.99 is obese (class 2 – moderate risk)

Now Calculate Your BMI
NOTE: The BMI Calculator is one of many tools to assess your weight. It is a useful measurement for most people over 18 years old, however it is only an estimate.
BMI Calculator For Athletes
It is not used for body builders, athletes, pregnant women, elderly or young children.
It does not take into account body weight defined as muscle or fat, just the number.
Those with a higher muscle mass, such as athletes, may have a high BMI but not be at a higher health risk.
Those with a lower muscle mass, such as children or the elderly, who may be losing muscle mass, may have a lower BMI.
During pregnancy and lactation, a woman’s body composition changes, so using BMI is not appropriate.
We also recommend you also check your measurements, and other risk factors. Remember to always visit you physician to discus your concerns about your weight.
