Enter your weight and height using standard or metric measures. Select "Compute BMI" and your BMI will appear below. It is used for both men and women, age 20 or older.
This is a graph of BMI categories based on the World Health Organization data. The dashed lines represent subdivisions within a major categorization. The Centers for Disease Control and Prevention CDC recommends BMI categorization for children and teens between age 2 and Being overweight increases the risk of a number of serious diseases and health conditions.
Below is a list of said risks, according to the Centers for Disease Control and Prevention CDC :. As can be seen from the list above, there are numerous negative, in some cases fatal, outcomes that may result from being overweight.
In some cases, being underweight can be a sign of some underlying condition or disease such as anorexia nervosa, which has its own risks. Consult your doctor if you think you or someone you know is underweight, particularly if the reason for being underweight does not seem obvious.
Although BMI is a widely used and useful indicator of healthy body weight, it does have its limitations. BMI is only an estimate that cannot take body composition into account. Due to a wide variety of body types as well as distribution of muscle, bone mass, and fat, BMI should be considered along with other measurements rather than being used as the sole method for determining a person's healthy body weight.
BMI cannot be fully accurate because it is a measure of excess body weight, rather than excess body fat. BMI is further influenced by factors such as age, sex, ethnicity, muscle mass, body fat, and activity level, among others.
For example, an older person who is considered a healthy weight, but is completely inactive in their daily life may have significant amounts of excess body fat even though they are not heavy.
This would be considered unhealthy, while a younger person with higher muscle composition of the same BMI would be considered healthy. In athletes, particularly bodybuilders who would be considered overweight due to muscle being heavier than fat, it is entirely possible that they are actually at a healthy weight for their body composition.
Generally, according to the CDC:. The same factors that limit the efficacy of BMI for adults can also apply to children and adolescents. Additionally, height and level of sexual maturation can influence BMI and body fat among children.
BMI is a better indicator of excess body fat for obese children than it is for overweight children, whose BMI could be a result of increased levels of either fat or fat-free mass all body components except for fat, which includes water, organs, muscle, etc.
In thin children, the difference in BMI can also be due to fat-free mass. Below are the equations used for calculating BMI in the International System of Units SI and the US customary system USC using a 5'10", pound individual as an example:. BMI prime is the ratio of a person's measured BMI to the upper limit of BMI that is considered "normal," by institutions such as the WHO and the CDC.
Since BMI prime is a ratio of two BMI values, BMI prime is a dimensionless value. A person who has a BMI prime less than 0.

Note that the calculator also computes the Ponderal Index in addition to BMI, both of which are discussed below in detail. BMI is a measurement of a person's leanness or corpulence based on their height and weight, and is intended to quantify tissue mass. It is widely used as a general indicator of whether a person has a healthy body weight for their height. Specifically, the value obtained from the calculation of BMI is used to categorize whether a person is underweight, normal weight, overweight, or obese depending on what range the value falls between.
