Where does your child stand today, and what's their range of possibility?
Enter your child's age, height and weight to see where they sit on the official CDC growth charts. Then set a goal line, such as the top 5%, and track it every 3 months.
Optional: parents' heights, to see the adult height range genes point to.

Height for age
Reference table · CDC growth charts
Top 5% height by age, ages 2 to 20
The height at which a child is taller than 95 out of 100 children of the same age and sex (the 95th percentile), with the average (50th percentile) for comparison. Show in cm
Possibility, at every age
A percentile is a snapshot. Growth is a story.
One number tells you where your child is today. The line it draws over months tells you far more. Track it like this:
- Pick a goal line: top 25%, top 10% or top 5%.
- Measure every 3 months, at the same time of day, without shoes, and compare each result with the goal line.
- Bring the record to checkups. It turns "is this normal?" into a real conversation.
