Adult BMI categories
Adults 20 and older only. BMI for children and teens is read with age and sex percentiles, which this calculator does not cover.
BMI does not measure body fat directly. Muscular people can score high, and older adults can score in range while carrying more fat. It is a screening number, not a diagnosis. This is not medical advice; talk to a doctor about what is right for you.
Why use this one
- Feet, inches and pounds by default. No converting. Switch to cm and kg with one tap and your numbers carry over.
- See where you land. A color scale shows your BMI next to each category, not just a number.
- A weight range, not only a label. Get the healthy BMI weight range for your exact height, in the units you use.
- Stays on this device. Your height and weight are remembered here only. No login, nothing uploaded.
