How tall is the average 5-year-old girl?

On the CDC stature-for-age chart, the median 5-year-old girl in the reference population measures 108.0 cm (3′ 6.5″). Half are shorter than that and half are taller, which is what "average" means here and is the reason a single number tells you very little on its own.

The usual range is wider than people expect. A 5-year-old girl at the 10th percentile is 102.0 cm (3′ 4.2″) and one at the 90th is 114.3 cm (3′ 9.0″) — 12.3 cm apart, and every child in between is on the chart exactly where they are supposed to be.

Computed from the CDC 2000 stature-for-age LMS parameters (L, M, S) interpolated to 5 years 0 months. These are the same tables a pediatrician's growth chart is printed from, and the same ones the app uses.

Where a percentile is and is not useful

A percentile says where a child stands against other children the same age and sex today. It does not say what they will reach as an adult, and it is not a grade. What matters far more than the number is whether a child holds their own line over time: a girl who has tracked the 25th percentile for three years is growing normally, and one who slid from the 75th to the 25th over the same period is worth a conversation with a pediatrician even though the second number looks unremarkable here.

Parents' heights set roughly the middle of where a child is likely to land. If you want the mid-parental target for your own child, the calculator on the front page does that arithmetic in the browser and nothing is sent anywhere.

Putting your own child on the chart

Height Predictor plots a child's measurements on the CDC curve above, keeps the history so the line is visible, and turns it into an adult-height range with the working shown. iPhone only for now.
