About BMI
BMI uses height and weight to estimate whether someone falls into a general weight category. It is useful as a quick screening tool, but it does not directly measure body fat, muscle mass, athletic build, or overall health.
- Underweight: below 18.5
- Normal: 18.5 to 24.9
- Overweight: 25.0 to 29.9
- Obese: 30.0 and above

BMI is a screening tool, not a full health diagnosis.
Healthy range is based on BMI 18.5 through 24.9 for your entered height.
