How to read your result

Length, then height

Under 2, babies are measured lying down (length), using World Health Organization charts. From age 2, children are measured standing up, using CDC charts.

The usual range

Most healthy children are between the 5th and 95th percentiles. A child outside that range can still be healthy. How your child grows over time matters more than one measurement.

Percentiles aren't targets

The 50th percentile is the middle. It isn't a height to aim for.

How to measure

  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.
