What’s typical at 11 for girls
Between 11 and 12, the median girl grows about 3 in (7.2 cm) — from 4'8½" to 4'11½".
A median 11-year-old girl has reached about 88% of the CDC's median adult height for women (5'4½"), so roughly 7½ in (19.4 cm) of growth is still typical from here.
The girls' growth spurt peaks around 11 to 12 on average, so this is the widest spread at any age: a girl who has finished her spurt and one who hasn't started can be a head apart and both be perfectly typical. Growth slows sharply after the first period, which comes around 12 to 13 on average.
How to read a percentile
A percentile compares a child with others of the same age and sex on the CDC 2000 growth charts — the same L, M and S values a pediatrician’s chart is drawn from, and where every number on this page comes from. The 50th percentile is the median: half of girls that age are shorter and half are taller. The 5th and 95th bracket the middle 90%.
Pediatricians care less about the number than the line. A child who stays near the same percentile year after year is growing normally, whatever that percentile is — a steady 15th is healthier than a 60th that has just dropped from the 90th. Crossing two of the major lines, or sitting below the 3rd, is the usual cue to have a pediatrician take a look. None of this is medical advice.

Height at 11 is one input. The calculator combines it with both parents’ heights and puberty timing to give the range adult height will most likely land in — free, no account.
