Understanding your BMI
Body Mass Index (BMI) is a simple ratio of weight to height. It is a rough screening tool, not a diagnosis.
Adult BMI ranges
- Below 18.5: underweight
- 18.5 to 24.9: normal weight
- 25 to 29.9: overweight
- 30 and above: obese
What BMI does not tell you
BMI does not distinguish muscle from fat, so athletes can score as overweight. It also does not reflect where fat is stored. Always discuss health concerns with a qualified professional rather than relying on a single number.
Frequently asked questions

What is a healthy BMI?
For most adults, a BMI between 18.5 and 24.9 is considered healthy.
Does BMI measure body fat?
No, it is only a ratio of weight to height and does not measure body fat directly.
