Is my daughter’s height normal?
Any height between roughly the 3rd and 97th percentile is common. What matters more is the trend: a child who stays on the same percentile line over the years is usually growing normally. Talk to a doctor if your child is below the 3rd percentile, much shorter than the parents’ heights suggest, has stopped growing, or has crossed two major percentile lines downward. See the height percentile calculator and height predictions for 15-year-old girls.

Frequently asked questions
Is 5'6" tall for a 15-year-old girl?
Yes. 5'6" is about the 80th percentile for girls aged 15, so taller than roughly 80 out of 100. Being tall at 15 can also mean an early growth spurt, so it doesn’t guarantee being tall as an adult.
Is 5'2" short for a 15-year-old girl?
5'2" is about the 23rd percentile for girls aged 15: below average but well within the normal range. Many girls who are shorter at 15 simply start puberty later and catch up.
How much will a 15-year-old girl grow?
At the median, girls grow about 0.3 in (0.7 cm) between 15 and 16, and about 0.6 in (1 cm) in total before adulthood. The real number depends on genetics and puberty timing.
How tall will a 15-year-old girl be as an adult?
A girl of median height at 15 is on track for about 5'4.5" (163 cm). For a personal estimate that also uses the parents’ heights, use the height calculator.
