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.

| 95 cm (3′1″) | 0.1% |
| 100 cm (3′3″) | 2% |
| 105 cm (3′5″) | 18% |
| 110 cm (3′7″) | 55% |
| 115 cm (3′9″) | 88% |

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.
