The Growth Check · Step 1 of 5

A two-minute check for parents who want a clearer growth conversation. Get a CDC-based percentile, a family-context range, and what to track next.

How old is your son?

Family-context percentile is calibrated by age. Whole years is fine.

This tool is for boys ages 8 to 16. Under 8 or over 16, growth is tracked differently.

How tall is he right now?

The most recent measurement you have is fine. Approximate is fine.

How tall is his mother?

Midpoint:

This is a statistical range. Real outcomes span a wider window because timing, nutrition, sleep, and genetic recombination all matter.

What this means

What's worth watching now

  • Measure his height every 6 months in the same conditions (morning, no shoes, back against a wall).
  • Watch the trend, not any single number. A boy staying near his percentile is normal.
  • Bring the trend — not just today's measurement — to his next pediatrician visit.
  • Sleep, nutrition, and physical activity influence growth. Genetics sets the ceiling.
We've sent this summary to your email. Watch for it in the next few minutes.

The Growth Check is parent education, not medical advice or diagnosis. Percentile calculations use CDC 2000 growth reference data for boys 2-20. Predicted adult height range uses the mid-parental height formula ± 8.5cm confidence interval. If you have concerns about your son's growth, talk to his pediatrician — with the trend in hand. © 2026 The Growth Path.
