Synopsis
This reference chart provides month-by-month height and weight measurements for female toddlers between 12 and 23 months of age, sourced from authoritative health organizations including the World Health Organization (WHO), the National Institutes of Health, and the Centers for Disease Control and Prevention. The data offers parents, caregivers, and healthcare providers a reliable baseline for tracking developmental milestones during this critical growth period. Presenting measurements in both imperial and metric formats makes the information accessible to families worldwide, while the straightforward table format allows for quick reference during pediatric appointments or home monitoring. Parents of children with disabilities or developmental concerns will find this particularly helpful for identifying potential growth variations that may warrant medical consultation, though the chart appropriately notes that individual measurements can naturally fall above or below these averages.At a Glance
- 1 - At 12 months the average girl measures 19.7 lb (8.95 kg) and 29.1" (74.0 cm).
- 2 - By 23 months she averages 24.8 lb (11.27 kg) and 33.7" (85.5 cm).
- 3 - Chart data is drawn from the World Health Organization and the U.S. Centers for Disease Control and Prevention.
Topic Definition
- Female Toddler Growth Chart
A female toddler growth chart is a reference table that lays out the average height and weight expected for girls between roughly one and two years of age, here covering 12 through 23 months. Rather than serving as a pass-or-fail test, it collects averages from large population studies so parents, caregivers, and doctors can see where a toddler sits alongside others her age. Its value comes from watching the pattern over time, since healthy toddlers grow along their own curves shaped by genetics, nutrition, activity, and any underlying health conditions. A girl's numbers can sit comfortably above or below the average and still be perfectly normal, which is why a chart like this works best as a starting point for tracking progress and for guiding a conversation with a pediatrician who can weigh the figures against her full health picture.
Overview
Understanding Height and Weight Changes in Toddler Girls
Female toddlers come in all shapes and sizes, so it is not always easy to know if your girl is following a healthy path regarding height and weight. However, keep in mind that the numbers in these types of charts are just a benchmark. Your girls' weight and height can often be higher or lower than the average.

| 12 Months | 19.7 lb. (8.95 kg) | 29.1" (74.0 cm) |

Frequently Asked Questions
How much weight should a toddler girl gain between 12 and 23 months?
Weight gain slows noticeably after infancy, so many toddler girls add only a few pounds across this whole year. Steady, gradual progress along her own curve matters far more than the exact amount gained in any single month.
Why does my toddler girl seem to eat less than she used to?
Appetite naturally dips as growth slows after the first year, and picky eating is very common at this stage. As long as she stays energetic and continues growing steadily, smaller or irregular meals are usually normal.
How should I measure my toddler's height at home?
Toddlers this age are typically measured standing against a wall with heels together and heels, back, and head touching the surface. Because home readings can vary, the standing height taken at a pediatric visit is the more reliable figure.
Do toddler girls and boys follow different growth patterns?
Yes, girls and boys have slightly different average weights and lengths, which is why separate charts exist for each. Comparing a toddler girl to boy averages can make her progress look off when it is actually right on track.
Does becoming more active affect a toddler girl's weight?
Yes, once toddlers start walking and running they burn far more energy, which can slow weight gain while length keeps increasing. This often makes a busy toddler look leaner than she did as a baby, which is generally healthy.
When should I raise growth concerns with a doctor?
It is worth speaking with a pediatrician if your toddler's weight or length flattens or drops across several checkups, or if she loses previously gained skills. A single off measurement is rarely cause for alarm on its own.
How These Figures Were Derived and Last Verified
Every number in the table above is the median (50th percentile) of a published growth reference, not an average of site visitors or an in-house estimate. The figures come from the WHO Child Growth Standards, which the CDC recommends for children under two years of age in the United States. In each row the imperial and metric values are converted from the source figure in its original unit and rounded consistently, so the two unit systems agree with one another. The complete set of figures was last checked cell by cell against the source data files on 26 July 2026, and matches our full height-to-weight guide for infants through teens.

Insights, Analysis, and Developments
Editorial Note: Growth charts remain one of pediatric medicine's most practical tools, yet their real value lies not in rigid adherence to averages but in revealing patterns over time. While these WHO and CDC benchmarks reflect typical development for female toddlers, every child follows her own trajectory influenced by genetics, nutrition, activity levels, and underlying health conditions. What matters most isn't whether a toddler hits exact numbers at specific months, but rather that she maintains consistent progress along her personal growth curve. For families raising children with disabilities or chronic conditions that affect growth - whether related to nutrition absorption, mobility, or metabolic function - these charts become conversation starters rather than judgment tools, helping healthcare teams identify when intervention might optimize development and when patience simply allows nature to unfold at its own pace.
