A 27-month-old typically weighs between 22 and 33 pounds, with the average falling right around 26 to 27 pounds. Boys tend to weigh slightly more than girls at this age, but the healthy range is wide. A child who’s been growing steadily along their own curve on a growth chart is almost certainly on track, even if they’re smaller or larger than average.
Average Weight by Percentile
Growth charts plot your child’s weight against thousands of other children the same age and sex. The 50th percentile is the statistical middle, not a target. A child at the 25th percentile is just as healthy as one at the 75th, as long as they’re following a consistent pattern over time.
For 27-month-old girls, the WHO growth standards show these benchmarks:
- 5th percentile: about 21.8 pounds (9.9 kg)
- 50th percentile: about 26.7 pounds (12.1 kg)
- 95th percentile: about 33.1 pounds (15.0 kg)
Boys at the same age run slightly higher across all percentiles, typically 1 to 2 pounds more. If your child falls anywhere between the 5th and 85th percentiles and has been growing steadily, that’s considered a healthy weight range. Below the 5th percentile is classified as underweight, while above the 85th is considered overweight and above the 95th is classified as obesity. These cutoffs apply to children aged 2 and older using BMI-for-age charts.
Why the Range Is So Wide
Genetics play the biggest role in where a toddler lands on the growth chart. Tall parents tend to have taller, heavier kids. Shorter parents tend to have smaller ones. Premature babies and those who were small at birth sometimes track along lower percentiles for years without any underlying problem. The same goes for larger babies who consistently track high.
What matters far more than the number on the scale is the pattern. A child who’s been at the 20th percentile since infancy and stays there is growing normally. A child who drops from the 60th to the 15th percentile over a few months may need evaluation, even though the 15th percentile is technically within the healthy range.
How Fast Toddlers Gain Weight
Growth slows dramatically after the first year. Between ages 2 and 3, most children gain about 4 to 6 pounds over the entire year. That works out to roughly a pound every two to three months, which can feel like almost nothing compared to infancy. It’s also common for toddlers to gain in spurts, staying at one weight for weeks and then jumping up seemingly overnight.
Height increases at a similar pace, around 2 to 3 inches per year. Because toddlers are getting taller and more active without gaining much weight, many look noticeably leaner than they did as babies. The round belly and chubby limbs of infancy start giving way to a longer, more proportional body. This is completely normal and not a sign that your child isn’t eating enough.
Which Growth Chart to Use
The CDC recommends using WHO growth charts for children from birth through age 2, then switching to CDC growth charts from age 2 through 19. At 27 months, your child has just crossed that transition point. It’s worth knowing that switching charts can sometimes shift a child’s percentile slightly, since the two charts are based on different data sets. A small jump or dip in percentile at the 2-year mark doesn’t necessarily reflect an actual change in growth.
Your pediatrician’s office handles this transition routinely. If your child’s percentile looks different at the 2-year visit compared to earlier checkups, ask whether the chart change explains it before worrying.
What Healthy Eating Looks Like at This Age
An average 2-year-old needs about 1,000 to 1,400 calories a day, depending on how active they are. That’s not a lot of food, and toddlers are notoriously unpredictable eaters. Many go through phases where they eat almost nothing one day and make up for it the next. Others fixate on a single food for weeks before abruptly losing interest.
The best approach is offering a variety of foods at regular meals and snacks, then letting your child decide how much to eat. Whole milk or fortified milk alternatives, fruits, vegetables, whole grains, and protein sources like eggs, beans, or small pieces of meat cover the basics. At this age, portion sizes are small. A serving of protein for a toddler is about the size of their palm, and a serving of fruit is a few tablespoons.
Toddlers who drink too much milk (more than about 16 to 24 ounces a day) sometimes eat less solid food and can miss out on iron and other nutrients. If your child seems to fill up on milk and skip meals, cutting back on milk portions and offering it after food rather than before can help.
Signs That Weight May Be a Concern
A single weight measurement doesn’t tell the full story. Pediatricians look at the trend across multiple visits. The most important red flag is a child who steadily falls off their expected growth curve, dropping through percentile lines over several months. This pattern, sometimes called failure to thrive, means the child isn’t gaining weight at the expected rate for their age.
Other signs worth noting include a child who seems unusually tired or low-energy, has little interest in food over a sustained period (not just a picky phase), or isn’t meeting physical milestones. By 27 to 30 months, most toddlers can jump with both feet off the ground, kick a ball, twist doorknobs, and pull off loose clothing. If your child is growing steadily and hitting these milestones, their weight is very likely fine, wherever it falls on the chart.
