Detailed Guide
BMI offers a fast population-level screening indicator and is useful for broad trend monitoring.
It should not be treated as a standalone diagnosis because body composition and fitness level can vary widely.
For practical use, combine BMI with other indicators such as waist measures, activity, and clinical context.
This calculator is best for orientation and tracking, not for replacing professional medical evaluation.
Assumptions and Limits
BMI is a screening metric and does not directly measure body fat, muscle mass, or health diagnosis.
Common Mistakes to Avoid
- Entering height in meters when the field expects centimeters.
- Treating BMI category as medical diagnosis.
- Comparing children and adult BMI categories directly.
