Height chart for 1-Year-Old boys

Height at 1-Year-Old: what the data shows for toddler boys.

Height percentiles for 1-Year-Old boys

CDC growth chart data shows the following height distribution for toddler boys at 1-Year-Old:

• 5th percentile: 70.4 cm (2 ft 3.7 in)

• 25th percentile: 73.0 cm (2 ft 4.7 in)

• 50th percentile (median): 74.9 cm (2 ft 5.5 in)

• 75th percentile: 76.9 cm (2 ft 6.3 in)

• 95th percentile: 80.0 cm (2 ft 7.5 in)

Percentiles rank your child's measurement against a reference population of toddler boys. The 50th percentile is the midpoint - half measure above it and half below.

Height and development for toddler boys

One-year-olds have typically grown around 25 cm from their birth length - one of the most dramatic periods of linear growth in human life. From the first birthday onward, the pace of height gain slows to approximately 10-12 cm per year through early childhood.

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.

For personalised guidance, consult a paediatrician or healthcare provider who can assess your child's measurements in the context of their full growth history.
