Use this BMI calculator to estimate body mass index based on height and weight.
BMI, or body mass index, is a general screening measurement that compares weight to height. It can be useful for understanding broad weight categories, but it does not measure body fat directly and does not diagnose health.
BMI is a screening indicator and does not measure body fat directly. It can misclassify athletes, the elderly, and pregnant women. For personalized health advice, consult a qualified medical professional.

What This Tool Does
BMI is a simple calculation that uses height and weight. It may place a person into a general category such as underweight, healthy weight, overweight, or obesity.
However, BMI does not consider muscle mass, bone structure, age, sex, pregnancy, body composition, ethnicity, athletic training, or medical history. For that reason, BMI should be used only as a general screening estimate.
Common Uses
You can use this BMI calculator to:
- Estimate your BMI
Understand general BMI categories - Track the broad body measurement changes over time
- Prepare questions for a healthcare provider
- Use a quick reference for general wellness planning
Example
If a person enters their height and weight, the calculator estimates BMI using a standard formula. The result can give a general category, but it cannot determine whether a person is healthy or unhealthy by itself.
Limitations
BMI is not a diagnosis. It may be inaccurate for athletes, older adults, children, pregnant individuals, and people with higher or lower muscle mass.
