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.

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.
