Average Height for a 11 Year Old Girl (CDC Data)
The average (50th percentile) height for a 11-year-old girl is 4'4" (133 cm), based on CDC/NCHS 2000 growth charts. Half of girls this age are taller and half are shorter.
Average Height for a 11 Year Old Girl
Pediatricians use CDC growth charts to track adolescent growth during puberty. At age 11, the median stature for girls—the 50th percentile—is 133 cm (4'4").
Teenage height varies enormously depending on puberty timing. Two 11-year-olds can differ by 6+ inches and both be normal if each is tracking consistently on their own percentile curve.
The table below shows CDC stature-for-age percentiles for 11-year-old girls. Use these alongside your pediatrician's growth charts at annual checkups.
CDC Growth Chart Percentiles — 11 Year Old Girl (Stature)
| Percentile | Height (cm) | Height (ft-in) |
|---|---|---|
| 5th | 121 cm | 3'11" |
| 10th | 124 cm | 4'1" |
| 25th | 128 cm | 4'2" |
| 50th | 133 cm | 4'4" |
| 75th | 138 cm | 4'6" |
| 90th | 142 cm | 4'8" |
| 95th | 145 cm | 4'9" |

Is My Child's Height Normal?
During adolescence, temporary comparisons to the average can be misleading because puberty timing differs. A 11-year-old girl who has not yet started puberty may be shorter than peers who have—without any underlying problem.
What matters most is growth velocity and percentile tracking over time. A steady pattern along the 15th or 85th percentile is usually normal; crossing multiple percentile lines rapidly may warrant evaluation.
Heights below the 5th or above the 95th percentile at age 11 should be discussed with a pediatrician, especially if accompanied by other symptoms or a sudden change in growth rate.
For a 11-year-old girl, the CDC defines a typical range from the 5th percentile (121 cm / 3'11") to the 95th percentile (145 cm / 4'9"). Heights within this band are generally considered normal for age. Percentiles below the 5th or above the 95th warrant a conversation with your pediatrician—not necessarily a problem, but worth monitoring.
How Much Will They Grow From Here?
Adolescence is when the most dramatic height changes occur. Girls ages 11–14 experience wide variation in growth timing—early, average, and late bloomers can differ by several inches at the same age.
At age 11, many girls are in puberty with accelerated growth. Girls typically have their peak height velocity around ages 11–13—earlier than boys—and finish growing sooner.
Growth velocity at age 11 is typically about 6–8 cm per year (puberty growth spurt). A girl at this age has about 30–35 cm of growth remaining, though girls finish growing earlier than boys. Individual timing varies widely based on genetics and puberty onset.
