What is a Healthy BMI Range?
For most adults aged 20 and older, a healthy BMI range is clinically defined by the World Health Organization (WHO) as being between 18.5 and 24.9 kg/m². Scores within this target boundary correlate with lower standard cardiovascular and metabolic risks.

The standard health parameters segment scores into clear, comparative classifications:
| BMI Score (kg/m²) | Clinical Classification | Standard Risk Profile |
|---|---|---|
| < 18.5 | Underweight | Moderate Concern |
| 18.5 – 24.9 | Healthy Weight | Low Risk |
| 25.0 – 29.9 | Overweight | Increased Risk |
| 30.0 + | Obese | High Health Risk |
Age and Pediatric Variations
Healthy boundaries change when evaluating children or older populations. For teens and toddlers, growth percentiles are mapped against sex-specific developmental milestones rather than static adult metrics.
