Kids may grow as much as 15 inches and gain fat and muscle as their bodies begin to grow and gain that adult shape.

Some kids hit puberty as early as 8 years old and others experience puberty late.

What Factors Determine the Average Weight?
The particular average weight of 13-year-old kids is a lot harder to deduce and that is because a lot of other things can influence the body weight of young kids.
Rate of Development:
Children generally enter puberty between the ages of 8 and 14 years old.
However, they don’t enter puberty at once and while some hit puberty very early, some do not experience it until later.
Some kids may have finished undergoing puberty when some are just starting and this makes it much harder to pin down a particular figure for the average weight of a 13-year-old.
The Kid’s Height and Body Makeup:
The height of your child also determines their weight in most cases. Taller kids tend to weigh more than shorter ones.
Muscle weighs more than fat and this is the reason why kids with more muscle mass and bone density tend to weigh more than their counterparts.
A more muscular child will most likely weigh more than a child who is a learner or one who has fat instead of muscle.
While the type of Diet and activity the child engages in may play a role in their body shape, Genetics also plays a key role too.
People from different genetic backgrounds often have different body compositions that may further determine their body shape, size, and weight.
Where a child lives is also a factor that can influence the size of their body.
This is due to several smaller reasons like the type of food they eat, cultural practices, environment, and other factors.
Body Mass Index:
This takes into consideration more than just factors that may determine the weight of your child.
It is a standard procedure that calculates body fat percentage using height and weight.
To calculate your child’s BMI, you can use a BMI calculator and input the child’s age, sex, weight, and height from which you’ll get a result that shows if your child is underweight, has a healthy weight, overweight or obese.
- Less than the 5th percentile means the child is underweight.
- The 5th percentile to 85th percentile means the child had a healthy weight.
- 85th percentile to 95th percentile means the child is overweight.
- 95th percentile and greater means that the child is obese.
Why is BMI Measurement Important?
Kids who are overweight or obese are at risk of developing type 2 diabetes and other weight-related health issues. They are also at risk of heart problems.
BMI measurement is not always accurate as it doesn’t calculate muscle mass and other factors which may affect the body’s weight.
Speaking to your Child about Weight and Image:
Your child may have some questions to ask you when they begin to undergo puberty.

Educate Your Child on How Puberty Works:

Talk About Positive Self-Image:
There are different body shapes and different body sizes. You need to ask your kid what type of body they think they have and what they like about their body type.
Make sure your kids have a positive self-image and make sure they do not say hurtful nicknames to themselves or other kids. Names like fat and skinny should not be allowed also.
Discuss what they Learn from Media:
Make sure you always talk to your children about what they learn from social media and television.
Movies and music videos do more harm than good to kids in terms of body positivity.
Monitor your Child’s Internet Habits:
It may also help to set some rules and monitor how your kid uses the internet so they don’t take negative messages regarding their body.
Help your Kids Cultivate Healthy Eating and Exercise Habits:

Skipping sugary beverages and taking part in small exercises like walking around the neighbourhood can also help.
