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.

Frequently asked questions
Is 5'6" tall for a 17-year-old girl?
Yes. 5'6" is about the 76th percentile for girls aged 17, so taller than roughly 76 out of 100. Being tall at 17 can also mean an early growth spurt, so it doesn’t guarantee being tall as an adult.
Is 5'2" short for a 17-year-old girl?
5'2" is about the 20th percentile for girls aged 17: below average but well within the normal range. Many girls who are shorter at 17 simply start puberty later and catch up.
How much will a 17-year-old girl grow?
