What does a height percentile mean?
Picture a hundred children the same age from the WHO reference, girls with girls and boys with boys. A baby on the 50th percentile for length or height is taller than half of them and shorter than the other half. A baby on the 15th is above fifteen of them.
The 50th is the median. That’s usually what people mean by the average for an age. It’s the middle, not a target. If a number worries you, ask your pediatrician. They know the rest of the picture.
There’s also the weight chart and the head circumference chart.
Keep every measurement in one place.
