What Is BMI?

BMI, or Body Mass Index, is a simple calculation based on a person's height and weight. It is commonly used as a general screening measure to estimate whether a person's weight falls within a particular range for their height.

BMI Categories

BMI Range Category
Below 18.5 Underweight
18.5 – 24.9 Healthy Weight
25.0 – 29.9 Overweight
30.0 or higher Obesity

How Is BMI Calculated?

BMI is calculated by dividing weight in kilograms by height in meters squared.

For example, if someone weighs 65 kg and is 1.70 meters tall, the BMI is approximately 22.49.

BMI Calculator FAQs

What does BMI mean?

BMI stands for Body Mass Index. It is a commonly used screening measurement based on height and weight.

How do I calculate my BMI?

Enter your height in centimeters and weight in kilograms into the calculator above, then click Calculate BMI.

What is considered a normal BMI?

For adults, a BMI from approximately 18.5 to 24.9 is commonly classified as the healthy-weight range.

Is BMI a medical diagnosis?

No. BMI is a screening measurement and should not be treated as a diagnosis. Factors such as age, sex, muscle mass and overall health can also be important.

Can athletes have a high BMI?

Yes. People with substantial muscle mass can have a higher BMI because BMI does not directly distinguish between muscle and body fat.
