How to Read Your BMI
| BMI (kg/m²) | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5–24.9 | Normal |
| 25–29.9 | Overweight |
| 30 and above | Obese |
These are the standard adult cut-offs used by the calculator. BMI is a screening measure: it does not distinguish muscle from fat, and it is not meant for children or pregnant people.
