Calculate BMI
Use this calculator to check your body mass index (BMI), which can be a helpful tool in determining your weight category. Or, use it to calculate your child’s BMI.

People who are overweight or obese are at higher risk for chronic conditions such as high blood pressure, diabetes, and high cholesterol.

Anyone who is overweight should try to avoid gaining additional weight. Additionally, if you are overweight with other risk factors (such as high LDL cholesterol, low HDL cholesterol, or high blood pressure), you should try to lose weight. Even a small weight loss (just 10% of your current weight) may help lower the risk of disease. Talk with your healthcare provider to determine appropriate ways to lose weight.

What is Body Mass Index?

The BMI is an attempt to quantify the amount of tissue mass (muscle, fat, and bone) in an individual, and then categorize that person as underweight, normal weight, overweight, or obese based on that value. However, there is some debate about where on the BMI scale the dividing lines between categories should be placed. Commonly accepted BMI ranges are underweight: under 18.5 kg/m2, normal weight: 18.5 to 25, overweight: 25 to 30, obese: over 30. People of Asian descent have different associations between BMI, percentage of body fat, and health risks than those of European descent, with a higher risk of type 2 diabetes and cardiovascular disease at BMIs lower than the WHO cut-off point for overweight, 25 kg/m2, although the cutoff for observed risk varies among different Asian populations.

Body Mass Index Formula

The formulas to calculate BMI based on two of the most commonly used unit systems:

Metric UnitsBMI = weight (kg) / (height2)(m2)U.S. UnitsBMI = 703 * weight(lb) / (height2)(in2)
