P50 is the median: half of children the same age are shorter and half taller. P3 to P97 is the range WHO treats as normal.
| Height | Children shorter |
|---|---|
| 75 cm (2′6″) | 0.1% |
| 80 cm (2′7″) | 4% |
| 85 cm (2′9″) | 41% |

Values come straight from World Health Organization tables: the WHO Child Growth Standards (2006) for ages 0–5 and the WHO Growth Reference (2007) for ages 5–19. National references (CDC in the US, for example) can differ by a few centimetres. This is not a diagnostic tool: growth over time matters more than a single measurement, and questions about your child's growth belong with their doctor.
