Boys Weight chart in lbs for Preschoolers 4 years & 6 months old

Weight chart for 4 Years 6 Months boys

How weight typically progresses for preschool boys at 4 Years 6 Months.

Weight percentiles for 4 Years 6 Months boys

Growth chart data from the CDC shows weight percentiles for preschool boys at 4 Years 6 Months as follows:

• 5th percentile: 31.5 lbs

• 25th percentile: 35.0 lbs

• 50th percentile (median): 37.9 lbs

• 75th percentile: 41.4 lbs

• 95th percentile: 47.6 lbs

The percentile values on this page are displayed in lbs.

Growth chart percentiles describe where your child's measurement sits among preschool boys measured in the CDC reference study. At the 50th percentile, the measurement is right at the middle of the typical range.

Weight and development for preschool boys

Preschool-age children typically gain around 2 kg per year. At 4 years old, active play is one of the most important contributors to healthy weight patterns. Structured and unstructured physical activity for 3-5 year olds ideally totals at least 3 hours per day, including energetic activity that raises the heart rate.

Supporting intuitive eating in preschoolers

Preschoolers are naturally intuitive eaters - they are generally good at regulating their own intake. Avoid cajoling, bribing, or pressuring children to eat more or less than they want, as this can undermine the natural hunger and fullness cues that support healthy weight. Aim for three meals and 2-3 small snacks per day, with water or milk as the main drinks.

Physical activity at this age

At least 3 hours of physical activity daily for preschoolers is recommended, including at least one hour of energetic play that raises the heart rate. This does not need to be structured sport - active outdoor play, dancing, and chasing games all count. Limiting screen time and encouraging movement throughout the day is the most practical approach at this age.

Frequently asked questions

How much weight does a child gain per year?

After infancy, the rate of weight gain slows considerably. Toddlers typically gain 1.5-2 kg per year, preschoolers around 2 kg per year, and school-age children 3-5 kg per year. During puberty, the rate accelerates significantly - 4-8 kg per year is common during the peak growth phase.

Should I be concerned if my child's weight has stayed the same for a few months?

Brief weight plateaus are common in growing children and are usually not a cause for concern if the child appears healthy, has a good energy level, and is growing in height. A plateau of 3 months or more, particularly if accompanied by any health concerns or a fall across percentile lines, is worth discussing at the next GP or child health check.

What is a healthy weight for this age?

The percentile table on this page shows the full range of typical weights. All values from the 5th to the 95th percentile are within normal limits. Weight at a single point in time is less informative than a consistent growth pattern - a child who has always been at the 25th percentile and remains there is growing normally.

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.
