Average height for a 2-year-old girl
At exactly 2 years old, the median girl in the US is 2'9½" (85.0 cm) tall, according to the CDC growth charts. Half of 2-year-old girls are between 2'8½" and 2'10½", and about 9 in 10 fall between 2'7" and 2'11½".

What’s typical at 2 for girls
Between 2 and 3, the median girl grows about 3½ in (8.9 cm) — from 2'9½" to 3'1".
A median 2-year-old girl has reached about 52% of the CDC's median adult height for women (5'4½"), so roughly 31 in (78.4 cm) of growth is still typical from here.
This is the steady stretch of childhood: growth runs at a fairly even pace and most girls track along the same percentile line year after year. Puberty typically begins between 8 and 13 for girls, and the growth spurt comes early in it.
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.
How tall will a 2-year-old girl be as an adult?
Height at 2 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.
