What it means

In inches, the usual range for a 17-year-old is 64.2 to 73.6 in for boys and 60.0 to 68.3 in for girls (5th to 95th percentile).

For a 17-year-old, the median for boys is 4.9 in more than for girls (69.0 vs 64.1 in).

Standing height from age 2. From age 2, children are measured standing up and compared with CDC growth charts. Under 2, babies are measured lying down (length), using World Health Organization charts.

What's a usual range? Most healthy children are between the 5th and 95th percentiles. Many healthy children are shorter or taller than that. What matters is how your child grows over time.

Percentiles aren't targets. The 50th percentile is the middle: half of children are taller and half are shorter. It isn't a height to aim for.

How to measure your child

  1. Measure your child standing straight without shoes, looking straight ahead.
  2. Write down the height to one decimal place, in inches or centimeters.
  3. Use the same method each time you compare.

Common questions

Short answers about how these calculators work.

World Health Organization length charts from birth to 23 months. From 24 months, including age 2, we use CDC height charts.

On these growth charts, the 50th percentile for boys is a little above the one for girls at most ages. It describes the children measured for the charts. It isn't a goal.
