Height chart for 6-Month-Old girls

How tall should a 6-Month-Old be? Here is what the growth charts say.

Height percentiles for 6-Month-Old girls

The CDC growth charts provide the following height percentiles for baby girls at 6-Month-Old:

• 5th percentile: 23.7 in

• 25th percentile: 24.7 in

• 50th percentile (median): 25.4 in

• 75th percentile: 26.0 in

• 95th percentile: 27.0 in

The percentile values on this page are displayed in inches.

Growth percentiles place your child's measurement on a scale from 1 to 99 relative to baby girls. The 50th percentile represents the middle of the typical range.

What to expect at 6-Month-Old

At six months, length is typically around 65-68 cm for boys and 63-66 cm for girls. This milestone is reviewed at the six-month health check.

How to measure at home

At every health check, your baby's length, weight, and head circumference are plotted on the growth chart. If you are measuring at home between checks, use a firm surface and a non-stretch tape measure, and have the same person measure each time for consistency. Measure in the morning if possible, when the body is at its maximum length before the day's activity causes minor compression.

Reading the growth chart

What matters most is not where the measurement falls on any single day, but whether your baby is following a consistent channel over time. Growth is rarely perfectly smooth - there will be brief plateaus and bursts. If your baby's length crosses two percentile lines over several weeks in either direction, ask for a review at your next health check.

Frequently asked questions

What is a normal height for a baby at this age?

Normal height for babies covers a wide range. The percentile table above shows the spread from the 5th to 95th percentile - all values within this range are considered within normal limits. Being at the 10th percentile is entirely healthy if growth is consistent over time.

Does height at this age predict adult height?

Early infant length has only a modest correlation with final adult height. Genetics is the strongest predictor of eventual height, but the intrauterine environment, birth order, and early nutrition also play a role. Most children settle into their genetically determined percentile channel by age 2-3.

How is infant length measured?

Infant length is measured using a measuring board (infantometer) with the baby lying flat, head touching a fixed plate and legs fully extended. Two people are needed for an accurate measurement. Home measurements using a tape measure on a flat surface are less accurate but useful for tracking trends.

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.
