Growth Percentiles

Growth percentiles compare your child to other children of the same age and gender. They show what percentage of children are smaller.

How to interpret percentiles:

  • 50th percentile: average — half of children are smaller, half are larger
  • 25th-75th percentile: normal range — most children fall here
  • 5th-95th percentile: still within normal limits
  • Below 5th or above 95th: may warrant discussion with pediatrician

Key points:

  • Consistent growth along a percentile curve is more important than the specific percentile
  • Crossing two or more major percentile lines (up or down) may need evaluation
  • Genetics play a major role — tall parents tend to have taller children
  • Growth spurts can cause temporary jumps between percentiles
  • This calculator uses simplified reference data. For precise percentiles, consult your pediatrician with WHO/CDC growth charts.
