Understanding Height Percentiles
Height percentiles are a statistical tool used to compare an individual's height to others of the same age and gender. They help healthcare professionals, parents, and individuals understand where someone stands relative to the general population in terms of height.
Our calculator uses data based on WHO (World Health Organization) and CDC (Centers for Disease Control) growth charts to provide accurate percentile rankings. These charts represent the height distribution of healthy populations and serve as the standard for growth assessment worldwide.
Height Percentile Categories
| Percentile Range | Category | Interpretation | Population Distribution |
|---|---|---|---|
| 97th percentile and above | Very Tall | Exceptionally tall for age and gender | Top 3% of population |
| 90th - 97th percentile | Tall | Above average height | 7% of population |
| 75th - 90th percentile | Above Average | Taller than most people | 15% of population |
| 25th - 75th percentile | Average | Normal height range | 50% of population |
| 10th - 25th percentile | Below Average | Shorter than most people | 15% of population |
| 3rd - 10th percentile | Short | Below average height | 7% of population |
| Below 3rd percentile | Very Short | Significantly below average | Bottom 3% of population |
