What Is the Average Weight of a 10 Year Old? (BMI Ranges)

Average weight of a 10-year-old

Do you wonder if your child grows like other kids? As parents, we often compare kids’ progress to averages. All kids grow at their own pace. But knowing normal weight for a 10-year-old gives health insights.

The average 10-year-old boy weighs 70 pounds, while the average 10-year-old girl weighs 72 pounds. As kids hit puberty between ages 8-13, girls tend to weigh more than boys. 10-year-old boys typically weigh 53-109 pounds. 10-year-old girls often weigh 53-113 pounds.

Average Weight for 10-Year-Old Boys

The weight range for 10-year-old boys can vary considerably. The typical weight range for boys at this age is between 53 and 109 pounds (24 -49.4 kg).

PercentileWeight (Pounds)Weight (Kg)

This table illustrates the distribution of weights for 10-year-old boys based on percentiles.

According to this data, a boy at the 50th percentile would weigh about 70 pounds (31.7 kg), which represents the average weight. A weight below the 5th percentile is considered underweight, while a weight above the 95th percentile is considered overweight.

Be mindful that every child is unique and can have growth spurts at different times. Always consult with a pediatrician if you have concerns about your child’s growth pattern.

Average Weight for 10-Year-Old Girls

The average weight of a 10-year-old girl can vary significantly due to factors like genetics and activity level. However, according to CDC growth charts, the average weight typically falls between 53 to 113 pounds (24 to 51.2 kg).

PercentileWeight (Pounds)Weight (Kg)

As you can see from the table, a 10-year-old girl in the 5th percentile weighs around 72 pounds (32.6 kg), while a girl in the 95th percentile weighs around 106 pounds (48 kg).

Understanding Normal Growth Rates for Children

Growing up, your child will experience periods of growth spurts and plateaus. We call this the normal growth rate in children. Key indicators such as weight-for-age and height-for-age are charted on a child’s growth chart by doctors to monitor their development over time.

These metrics help identify ‘normal’ for an age range, like 10-year-olds here. It’s important not to compare your child with others but instead to track their progression on their personalized growth curve.

What is BMI? (BMI Ranges for 10-Year-Olds)

BMI, short for Body Mass Index, is a reliable indicator used to categorize a person’s weight. It uses a simple equation involving your height and weight, providing results that group you into categories such as underweight, healthy weight, overweight or obese.

The typical BMI range for a 10-year-old boy runs from 14.2 to 19.4, and the typical BMI range for a 10-year-old girl runs from 14 to 19.5.




  • A weight below the 5th percentile is considered underweight.
  • A healthy weight range is between the 5th and 85th percentiles.
  • Overweight is classified as a weight between the 85th and 95th percentiles.
  • A weight equal to or above the 95th percentile is categorized as obesity.

How to Calculate BMI for Children?

Metric Method:

  1. To get weight in kg: If weight is in pounds, multiply by 0.45359237.
  2. To convert height to meters: If the height is in cm, divide by 100. If already in meters, skip this.
  3. To get BMI: Divide weight (kg) by height (meters) squared.

Imperial Method:

  1. Multiply weight in pounds by 703
  2. Square height (inches) to get the right results.
  3. To get BMI: Divide weight (pounds) by height (inches) squared. Then multiply by 703.

Factors That Can Affect a Child’s Weight

Many things can change a 10-year-old’s weight. Like diet, sleep, exercise, and genetics. Growth spurts from puberty can also cause quick weight changes.

Health issues can also affect your kid’s weight. It is important to understand these influences to ensure optimal health for your child.


Good nutrition is key for a normal weight at age 10. The quality and amount of food can affect a kid’s growth.

High-calorie foods such as fast foods, baked goods, and vending machine snacks often lead to children gaining excessive weight while a lack of proper nutrient intake may result in malnutrition or underweight issues.

So kids need to eat healthy, balanced meals. These meals give them nutrients to grow. Good nutrition does more than prevent weight issues. It also boosts immunity, growth, and long-term health.

Sleep Habits

Correct sleep habits play a pivotal role in maintaining a healthy weight for 10-year-old children. Lack of sufficient sleep or poor-quality sleep is correlated strongly with childhood obesity.

When kids don’t have a regular bedtime, they are more likely to gain too much weight.

Not enough sleep can raise cortisol. This can lower growth hormones. Both hormones play a role in obesity.

Good sleep quality and duration help kids stay a healthy weight as they grow.

Physical Activity

Physical activity greatly impacts a child’s weight and overall health. Exercise bolsters cardiovascular fitness. It strengthens bones, and muscles, and manages weight. By engaging in regular exercise, children can also reduce various symptoms related to obesity or other health issues.

But as kids get older they tend to exercise less, even if not overweight. This needs to be fixed early. Importantly though, for those who are overweight or obese, active play serves as an efficient tool to reduce excess body fat.

Playing sports and active games helps 10-year-olds stay at a healthy weight.


Children’s weight can be heavily influenced by genetic factors. This is seen in how certain traits relating to body size and composition are inherited from parents, making some kids more susceptible to becoming overweight or obese.

Medical conditions that have a genetic component also play a part in childhood obesity. These include diseases such as Prader-Willi syndrome and Bardet-Biedl syndrome which can lead children to gain excessive weight despite eating healthy diets.

Puberty and Growth Spurts

Puberty is a critical phase in a child’s life when they experience significant hormonal changes leading to rapid physical development. Puberty often causes growth spurts. These spurts lead to big jumps in height and weight.

A child nearing or undergoing puberty may notice an increase above their usual annual weight gain, which averages around 6.5 pounds. Surprisingly, a child’s diet impacts growth spurts. Fatty, processed foods may cause earlier puberty.

Not all children enter this stage at the same age; proximity to puberty varies greatly among individuals due to factors such as metabolism rate, genetics, and psychological factors.

Parents should realize that fluctuating weights around this time are standard and part of normal adolescent development.

Underlying Medical Conditions

Certain health conditions can significantly impact a child’s weight and growth patterns. Some children might struggle with hormonal imbalances, such as hypothyroidism or hyperthyroidism, which could result in sudden weight gain or loss.

Genetic disorders also play an influential role, kids with Prader-Willi syndrome or Down syndrome often have higher body mass indexes (BMI) compared to their peers without these conditions.

Obesity can lead to problems like diabetes, high blood pressure, and heart disease later on.

Supporting a 10-Year-Old’s Growth

Leading a healthy life helps 10-year-olds grow. It also improves their health and happiness. Focus on nutritious food, daily activity, and less screen time.

Limiting Screen Time

Reducing screen time plays a vital role in promoting healthy growth and weight management for 10-year-olds. The American Academy of Pediatrics advises setting limits on device usage, such as no more than one to two hours per day for children aged two and above.

These guidelines foster healthier habits and help prevent childhood obesity.

Excessive screen time could potentially lead to harmful effects on early childhood development, including cognitive delay and disrupted sleep cycles. Between ages four and 11, device use typically peaks; therefore it’s crucial to establish boundaries at an early stage.

With active parental involvement, kids can enjoy balanced leisure activities while maintaining their well-being.

Importance of a Healthy Lifestyle

Living a healthy lifestyle serves as the cornerstone of growth for 10-year-olds. It goes beyond maintaining an optimal weight and delves into promoting strong cognitive development, emotional well-being, and social skills.

  • Physical fitness plays a pivotal role in achieving this goal. Regular exercise not only helps maintain a balanced weight but also improves mental health by relieving stress and boosting self-esteem.
  • A balanced diet to fulfill their varied nutritional needs. Eating nutrient-rich foods equips children with the necessary fuel for both body growth and brain development. However, indulging in unhealthy eating patterns can be detrimental leading to childhood obesity or chronic diseases.
  • Adequate sleep is paramount for overall health and emotional well-being too. Sleep deficiency can hinder academic performance, and mood regulation and increase susceptibility to various infections. Therefore encouraging good sleeping habits is equally important as emphasizing regular exercise and nutritious food.

Together, exercise, nutrition, and sleep are key for the best growth in 10-year-olds. Living healthy matters.

Underweight vs. Overweight

Being under or overweight at age 10 can show health risks. An underweight kid may have poor nutrition or eating issues. Their BMI is below the 5th percentile for their age and height.

Being underweight can limit a child’s growth. It can affect their development.

Obesity is also a risk. A child is overweight if their BMI is 85th to 95th percentile for their age.  Overweight children face different health challenges including heightened risk of pediatric obesity and body image issues that might persist into adulthood.

Parents are often more worried about obesity than being underweight.

When to Seek Medical Advice?

If your 10-year-old gains or loses weight rapidly, it may indicate a need for professional advice. Doctors are skilled in determining if fussiness about food or fluctuations in weight point to an underlying medical condition.

Medical professionals will consider the child’s physical activity level and eating habits as key factors when assessing health risks. Especially with the prevalence of childhood obesity at nearly 20%, parents must remain vigilant for abrupt changes that could raise concerns about their child’s well-being.

Physical Activity Recommendations for 10-Year-Olds

  • Aim for at least 60 minutes of moderate to vigorous physical activity every day.
  • Focus on bone-strengthening activities such as skipping or jumping, done at least three times a week.
  • Incorporate muscle-strengthening exercises, like gymnastics or push-ups, into the weekly schedule.
  • Encourage hobbies that promote movement, like dancing or cycling.
  • Promote team sports which not only build strength and fitness but also social skills.
  • Use breaks and free time in school for quick bouts of active games or sports.
  • Consider family outings that involve walking, swimming, or hiking.
  • Educate about the benefits of regular exercise to motivate your child to stay active.
