What BMI means
Body Mass Index is calculated as weight in kilograms divided by height in metres squared. It is a screening measurement used in adult population settings, not a direct measurement of body fat or a diagnosis. The same BMI value can mean different things for people with different body compositions and health backgrounds.
Important limitations
- Adult BMI categories are not intended for children and teenagers; age- and sex-specific growth charts are used for them.
- BMI does not distinguish muscle from fat or show where body fat is carried.
- Pregnancy, fluid changes, athletic build and some medical conditions can affect interpretation.
Use the result as a rough reference only. For an individual health assessment, discuss it with a qualified healthcare professional who can consider your wider health context.
