How this is calculated
Formula: BMI = weight (kg) ÷ height² (m²)
BMI divides weight in kilograms by height in meters squared. Imperial entries are converted before the same formula is applied.
Standard adult categories are the same for women and men, but BMI does not measure body fat or its distribution.
Pregnancy, older age, muscularity, menopause-related body-composition changes, and ethnicity can affect interpretation, so use BMI with other health information.
Standard adult BMI categories
| Category | BMI | Interpretation |
|---|---|---|
| Underweight | Below 18.5 | May warrant nutrition or medical review |
| Healthy-weight range | 18.5–24.9 | Population screening range |
| Overweight | 25.0–29.9 | Consider waist and other risk factors |
| Obesity | 30.0 or above | Discuss overall risk with a clinician |
Interpret BMI in context
Tips
- •Pair BMI with waist circumference, blood pressure, labs, fitness, and health history.
- •Do not use standard BMI categories during pregnancy.
- •Focus on sustainable behaviors rather than pursuing a single number.
- •Talk with a clinician about unexpected weight change or menstrual changes.

Frequently asked questions
The standard healthy-weight screening range for nonpregnant adults is 18.5–24.9. Individual health cannot be determined from BMI alone.
BMI is a population screening estimate, not a diagnosis or direct measure of body fat. It is not valid for pregnancy and may misclassify some people. Consult a healthcare professional for personal assessment.
