Height percentiles for 2 Years 9 Months girls
The height distribution for preschool girls at 2 Years 9 Months, based on CDC growth standards:
5th percentile: 33.9 in
25th percentile: 35.4 in
50th percentile (median): 36.4 in
75th percentile: 37.5 in
95th percentile: 39.0 in
The percentile values on this page are displayed in inches.
Percentile rankings compare your child's measurement against CDC reference data for preschool girls. The 50th percentile is the median - the midpoint of all measurements in the reference group.
What to expect at 2 Years 9 Months
Height between ages 2 and 3 typically increases at a rate of 9-11 cm per year. This is the period when children begin to stand for height measurement rather than being measured lying down - a change that can produce a small apparent decrease due to the different technique. Most children follow a consistent percentile channel from this age, making year-on-year comparison a useful tracking tool.
Best practice for home measurement
Height in the toddler and preschool years is best tracked by measuring every 6-12 months in the same conditions - ideally in the morning, without shoes, standing straight against a wall with heels touching the surface. Record each measurement with the date. Small variations between different measurers or times of day are normal.
Key growth indicators to watch
A child at the 25th percentile who stays at the 25th percentile is growing normally. A child who was at the 50th and has dropped to the 5th over 12 months warrants GP review. Chronic illness, nutritional deficiency, or prolonged stress can impair linear growth. Regular check-ups remain the most reliable way to identify any concerns early.
Frequently asked questions
Why is my child shorter or taller than their classmates?
Variation in height between children of the same age reflects differences in genetics, timing of puberty, nutrition, and general health - all of which are entirely normal. Children often go through growth spurts at different times, which can widen apparent differences temporarily before other children catch up.
How much does a child grow per year at this age?
Most school-age children grow approximately 5-6 cm per year between ages 5 and 10. During puberty, the growth rate accelerates to 7-10 cm per year at the peak of the spurt before slowing again. A growth rate below 4 cm per year in a school-age child outside of puberty is worth discussing with a GP.
What is a normal height for this age?
The percentile table on this page shows the full range of typical heights. All values from the 5th to the 95th percentile are considered within normal limits. Height at a single point in time is less informative than a consistent pattern of growth over months and years.
Data sources and methodology
The percentile ranges on this page are drawn from CDC growth chart data from the National Center for Health Statistics and WHO Child Growth Standards (for children under 5). CDC data published May 30, 2000, with 2022 extended BMI tables. Percentiles are modelled using the LMS method (Box-Cox transformation), which accounts for the skewed distribution of measurements at each age. All measurements are given in metric units with imperial equivalents.
These percentile ranges provide a population-level reference. A paediatrician or family doctor can give context specific to the individual's own growth trajectory.
