## What is the average 2nd grader height for boys?

What is the average 2nd grader height for boys? **The average height for a 2nd grader boy is 4 feet 2 inches tall, rounded to the nearest whole inch**.

The unrounded average 2nd grader height for boys is 4ft 1.6in or 126.1 centimeters.

Between the first and second grades, a boy will typically get around 3 inches taller.

Similarly, a 2nd grade boy will gain an additional 2.5 inches of height between the second and third grades. This rate of height growth will increase dramatically as a boy enters puberty.

## What is the average height of a 2nd grader girl?

What is the average height of a 2nd grader girl? **The average height for a 2nd grade girl is 4 foot 1 inch**.

During second grade, most girls are around an inch shorter than boys. But if a girl has an earlier birthday, then she may be taller than some of her male peers.

Since the time of first grade, a second grade girl will usually have gotten around 2 inches taller.

This rate of growth continues as she progresses into third grade, a timeframe that will see the average girl gain an additional 2 inches of stature.

## What is the average 2nd grader weight for boys?

What is the average 2nd grader weight for boys? **The average weight of a second grader boy is 61 pounds or 27.7 kilograms**.

Boys tend to be slightly heavier than their female peers at this age, which makes sense given that they’re also a bit taller on average and because weight and height tend to increase together as a child develops.

Since the previous grade, a second grade boy will have put on nearly 8 lbs of body mass. Some boys who are growing at a faster rate may gain more weight than this (the reverse of this is also true).

Similarly, between the 2nd and 3rd grades, a boy will gain approximately 9 lbs of body mass. So, as you can see, height and weight gain are very stable at this age.

## What is the average weight of a second grader girl?

What is the average weight of a second grader girl? **The average weight of a 2nd grader girl is 60.2 pounds or 27.3 kilograms**.

As mentioned, 2nd grade girls tend to weigh a bit less than 2nd grade boys, but not by much.

Also, if a girl is one of the *older* children in her class, then there’s a high chance that she’ll actually weigh **more** than many of her male peers due to her being more advanced in her physical development (i.e., she’ll probably be taller as well).

Between the first and second grades, a girl will have gained almost 8 lbs of body weight—the same as her male peers—and will go on to gain an additional 9 lbs of body weight (again, like 2nd grade boys).

These second grader growth trajectories show that, at this age, boys and girls grow at similar rates and have almost identical heights and weights.

## How can 2nd graders maintain a healthy body weight?

Second graders can maintain a healthy body weight and improve their health by performing plenty of physical activity.

An hour per day is the recommended minimum exercise duration for 2nd graders, which can take the form of running, jumping, skipping, swimming, or any other safe form of exercise that a child enjoys.

Research shows that physically active children have a higher peak bone mass, greater cardiovascular fitness, and a leaner physique than their more sedentary peers.

So if you want your second grader to be as healthy as possible, you should focus on increasing their activity level (and on ensuring good nutrition) rather than fixating on the numbers on the tape and scale.

## How old are 2nd graders in the USA?

How old are 2nd graders in the USA? **In America, second graders are 7 to 8 years old**. This corresponds to year 3 in UK school years, which is the first year of English junior school.

## In summary: How tall are second graders, and how much should they weigh?

We know that second graders are around 4 foot 1 or 4 feet 2 inches tall and weigh roughly 60 to 61 pounds on average.

But as I mentioned, health is not determined by the numbers on the scale or measuring tape.

So making sure that second graders are physically active, which certainly helps to maintain a healthy body weight, will improve their bone density, muscle strength, and cardiovascular fitness, all of which contribute to a child’s health.
