Body Mass Index (BMI) Assessment
Evaluate your body fatness using standard US indicators. This clinical screening tool helps identify potential health risks associated with underweight, overweight, and obesity classifications.
Clinical BMI Calculator
Please enter your height and weight accurately. The results are based on adult parameters (age 20 and older) established by federal health guidelines.

Note: BMI is a screening tool, not a diagnostic of body fatness or health. Athletes may have a high BMI due to increased muscularity rather than increased body fatness.
Understanding Your Body Mass Index (BMI)
Body Mass Index (BMI) is a person's weight in kilograms divided by the square of height in meters. A high BMI can indicate high body fatness. BMI screens for weight categories that may lead to health problems, but it does not diagnose the body fatness or health of an individual.
How is BMI used?
Healthcare providers use BMI as a screening tool to identify possible weight problems for adults. However, to determine if BMI is a health risk, a healthcare provider performs further assessments. Such assessments include evaluating diet, physical activity, family history, and other health screenings.
Limitations of the BMI Calculator
While the BMI calculator is widely used for health assessments, it does have limitations. It may overestimate body fat in athletes and others who have a muscular build. Conversely, it may underestimate body fat in older persons and others who have lost muscle mass.
