What Is the Average Weight of a 10 Year Old? (Quick Facts)

Average weight of a 10-year-old

Every child is different, we all know this. However, there are averages for everything in life, including weight. The average weight for a 10 year old is about 70.5 pounds.

With each child being different, there are a number of factors that could help determine the weight of both boys and girls.

  • Genetics and Metabolism
  • Gender
  • Lifestyle

Average Weight and Gender

As we know, boys and girls are different. There are thousands of differences in the genetic codes of both gender and, because of that, almost everything physical will be different. This includes height, weight, hair growth, voice, face shape, etc.

Typically, at age 10, girls are overall “bigger” than boys. This is because girls hit puberty before boys do. However, girls also finish puberty before boys do. So, while boys will keep growing and getting bigger, girls will slow down or completely stop.

On average, a 10 year old boy will weigh about 68 pounds while a 10 year old girl will weigh about 72 pounds.

Now, determining whether or not the weight of your 10 year old is healthy depends on a few things. One of the most important factors of this is the height. If your child is shorter and weighs more, there is a chance he or she will be considered overweight. It goes the other way too: if your child is taller and weighs the ‘average’ weight, he or she might be considered underweight.

Following growth charts is important for this reason. Also, using a BMI chart is helpful to determine a healthy weight-to-height ratio. However, you do need to look at the body type of the child. A more slender build might suggest being underweight even if the child is perfectly healthy. It’s best to talk to your child’s doctor about any concerns you have.

Genetics and Metabolism

Genetics is a huge factor in how weight is determined. Metabolism is directly related to genetics. If both parents have a slower metabolism then the child will most likely have a slower metabolism. If both parents have a fast metabolism, the child will most likely have fast one. If one parent has a slow and the other a fast metabolism, the child has a chance to have either a slow or a fast metabolism.

Gender does not play a role in the speed of your metabolism. Both boys and girls can have either a slow or fast metabolism. That is due to the genetics. Typically, children have faster metabolisms than adults.

Certain metabolic disorders can cause a person to either become overweight or become underweight. Your doctor or your child’s pediatrician can tell you if this is a problem for you or your children.

More often than not, newborns are screened for many of these metabolic disorders at birth. Discovering these disorders as early as possible is crucial to help prevent further health problems and even death.

Genetic disorders can also play a role in weight. Bardet-Biedl syndrome is a genetic disorder that causes many problems for a person. One of those problems is abnormal weight gains that usually starts in childhood and continues on into adult life.

Often times, kids with down syndrome also weigh more. This is partly because of the genetic disorder, but also because food tends to be used to soothe the upset child. It’s important to teach the child about healthy lifestyles.

Lifestyle and Weight

Believe it or not, the lifestyle you live can and will affect your children as they grow up. Your children follow what you do and mimic how you act. After all, you are their parent–you are their biggest role model.

Lifestyle is one of the biggest factors in weight for children, adolescents, and adults. It does not just include how physically active you are either. Lifestyle includes:

  • Physical activity
  • Diet
  • Attitude


Believe it or not, your attitude can affect your child’s weight. If you are constantly negative and stressed, your child might begin to cope with that by eating more than he or she should. Especially if that negative attitude begins to develop in your child.

It is important to try to be as positive around your children as you can. Having strong body confidence will help too. If your child sees you loving yourself and taking care of yourself from a young age, he or she will mimic that behavior and do the same.

It is very important to teach your children to love themselves and to be healthy in the way they eat, their physical activities, and the way they think. Positive families tend to be healthier. Pass this on to your babies!

Do things as a family, too. Eat meals at the table together. This has been proven to help children have a healthier weight and attitude about life. Play games together, support your children and encourage them to do what they believe.


No, diet doesn’t mean going on a diet and staying there forever. Diet just entails how you eat and what you eat. This is a huge factor in weight in childhood.

It is important to start giving your children healthy foods at a young age so as he or she gets older they enjoy them. Start your baby with veggies instead of fruit when introducing baby foods. They might not like it, but they will if that’s all you give them for a while.

As they get older, let them see you eating healthy. We aren’t saying to never go out and have some junk food, but teach them moderation with that. Encourage water over soda. Even fruit juices over soda is a better, healthier option! Avoid fast food from a young age so their brain doesn’t start to only want that.

Teaching your children how to have a healthy diet from a young age is important for their health. It is also good for your health! Show your children that healthy food is not ‘yucky,’ and that it really is delicious! There are endless options to having tasty and healthy meals.

It is also important to teach your children not to overeat. Help them learn about proper portions. If they are still hungry after, teach them to take a smaller second helping.

Physical Activity

Being active is also another large factor in weight in both children and adults. It’s best to help get your children active at a young as so that as he or she gets older, they will want to carry this on.

Being the example of healthy physical activity will help too. If you lead a sedentary lifestyle, your child will most likely end up living that lifestyle too. This can cause them to become overweight. Moving and being active helps to keep the metabolism moving, thus helping your child stay at a healthy weight. The less activity a child has, the more likely they are to gain unnecessary weight.

If your child is disabled and not able to get as much activity as other kids, it is really important to have a strict and healthy diet. Teach them to eat proper portions and only when hungry. Help them learn to make healthy meal and snack choices so as they get older, they can do it on their own.

If your child is disabled, do what you can to help them get more active. Talk to his or her pediatrician about what you can do to help your child get some exercise. Your child’s doctor will be more than happy to help you figure out what you can do to help your baby.

Remember, if you ever have any concerns about your child’s weight, then talk to his or her pediatrician right away. They will help you figure out what exactly is your concern and what you can do to help your child get healthier.
