Height chart for 17-Month-Old boys

Tracking height for toddler boys: percentiles, milestones, and what they mean.

Height percentiles for 17-Month-Old boys

CDC growth chart data shows the following height distribution for toddler boys at 17-Month-Old:

• 5th percentile: 75.5 cm

• 25th percentile: 78.4 cm

• 50th percentile (median): 80.5 cm

• 75th percentile: 82.6 cm

• 95th percentile: 85.8 cm

The percentile values on this page are displayed in cm.

A percentile ranking tells you where your child's measurement falls among toddler boys of the same age. The 50th percentile is the statistical midpoint of the population.

Height and development for toddler boys

Toddlers grow at a steadier and slower rate than infants, gaining around 10-12 cm per year between their first and third birthdays. Active play, adequate sleep, and good nutrition all support healthy linear growth at this stage. Growth spurts - brief periods of more rapid gain - occur intermittently and may briefly affect appetite and sleep patterns.

The transition to standing height

The transition from recumbent length to standing height measurement typically happens at 24 months. Standing height is usually 0.5-1 cm shorter than recumbent length due to spinal compression when upright, so there is sometimes an apparent drop at this transition. From age 2, plot your child's height on the 2-20 year CDC chart rather than the infant chart.

Tracking growth trends

A gradual change in percentile channel over a year or more is worth discussing with a GP, particularly if associated with any health concerns. Toddlers growing at the 25th percentile who consistently track along that line are growing normally. A child dropping from the 50th to the 5th percentile over 12 months warrants review.

Frequently asked questions

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.

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.

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.

Growth charts are screening tools, not diagnostic ones. If you have concerns about your child's measurements, a GP or paediatrician is the right first step.
