What is the average height for a 4 year old boy in feet? According to height data from a US anthropometric report, which measured 178 four year old males, the average height of a 4 year old boy in feet is 3 feet 6 inches tall.

For ease of consumption, this figure is rounded to the nearest whole inch. So, to be more specific, the average height for a 4 year old boy is precisely 3ft 5.6in, which works out at 105.9 cm tall.

A boy will typically gain 2.5 inches to 3 inches of height between the ages of 4 and 5, a trend which is likely to continue into his teenage years.

Height, as we’ve noted elsewhere, is largely genetically determined. However, environmental factors, such as diet, exercise, and sleep, can also influence how tall or short a child will be.

So, since 4 year old boys and girls need plenty of physical activity, it’s also important that they eat a balanced, nutritious diet and get around 10-12 hours of sleep every day.

What is the average height for a 4 year old girl in feet? According to anthropometric reference data, which measured the stature of 189 four year old females, the average height of a 4 year old girl in feet is 3 feet 5 inches tall.

Specifically, the researchers found that the average height for a 4 year old female was 3 feet 5.3 inches, which is equal to 105 cm.

As with 4-year-old boys, 4-year-old girls—who are virtually the same height as boys their age—will grow an additional 2.5 inches between the ages of four and five.

It’s interesting to note that, until a child’s teenage years, boys and girls are almost the exact same height at each milestone, with girls often being a bit taller than their male peers, especially during the early stages of puberty.

What is the average weight for a 4 year old boy? According to a Vital and Health Statistics report, the average weight of a 4 year old boy is 41 pounds.

This is equal to 18.6 kilograms and 2.9 stones.

As for a four year old boy’s body mass index, the same data source shows that the average BMI for a 4 year old boy is 16.5, which is considered to be in the normal range and therefore healthy.

Typically, a boy will gain 6-7 lbs of body weight between the ages of 4 and 5 as his bones keep growing, which can be aided by consuming a calcium-rich diet.

Interestingly, research shows that parents with overweight children tend to underreport their child’s weight, whereas parents with underweight children tend to overreport their child’s weight.

So since the above data for the average 4 year old weight was taken professionally (i.e., not at home by the parents), we can be quite certain that the numbers are fairly representative of the 4 year average weight across much of the US.

What is the average weight for a 4 year old girl? According to the available body mass data, the average weight of a 4 year old girl is 40 pounds.

This value, which is only a pound less than the average 4 year old weight for boys, works out at 18.14 kilograms and 2.85 stones.

As we can see, young boys and girls are very evenly matched in both height and weight, which, as mentioned, continues until boys start to experience rapid growth during puberty.

Like boys of the same age, 4-year-old girls will also typically gain around 6 or 7 pounds between the ages of 4 and 5.

In terms of body mass index, the average BMI for 4 year old girls is 16.4, which is considered to be healthy because it’s in the normal range for body mass index values.

How tall is a 4 year old on average in America? In the United States, the average height for a 4 year old boy is 3 feet 6 inches, while the average height for a 4 year old girl is 3 feet 5 inches.

The average height for 4 year olds will likely differ per country, and perhaps considerably so. 

Still, few countries have the data quality provided by US anthropometric research, which is why the average 4 year old weight and height—and that for other age groups—is typically representative of many different areas of the US.

In conclusion: Why should parents know the average weight for 4 year olds?

A person checking how much a 4 year old should weigh

Knowing the average weight for 4 year olds enables you to see how your four year old compares in body mass to other children of their age and gender.

Additionally, knowing the average height for 4 year olds as well will enable you to work out the average BMI for 4 years olds. 

Better yet, by finding out your own four year old’s weight and height, you can use simple online calculators to get their BMI, which is one way to assess whether they’re carrying too much (or too little) body mass.
