what is the average weight for a 13 year old ?

The average weight for a 13-year-old boy is between 75 or 145 pounds. Another side weight for a 13-year-old girl is between 76 and 148 pounds. For boys, the 50th percentile of weight is 100 pounds. For girls, the 50th percentile is 101 pounds. It’s important to notice that anywhere therein range is taken into account average, and not by itself considered overweight or underweight.

Puberty follows a singular timeline for every individual child. From the time it starts, kids may grow the maximum amount as 10 inches and gain muscle, fat, and bone as their bodies develop to the adult form. These changes may happen suddenly and involve rapid weight gain, which can cause feelings of self-consciousness as children suits their new bodies. Some may enter puberty as early as age 8. Others might not begin until they reach their early teens. As a result, there’s a good range of “normal” weights, shapes, and sizes.

The average weight of a 13-year-old can vary, counting on a variety of things. Puberty, for instance, can significantly affect a child’s weight and appearance, and therefore the timing of those changes is different for boys and girls.

The Centers for Disease Control and Prevention (CDC) have set guidelines for healthy weight and body mass index (BMI) in children.

These guidelines can help doctors and fogeys or caregivers monitor a child’s growth and determine whether or not they are underweight or overweight, for instance.

This article will discuss the typical weights for 13-year-old boys and girls, also as BMI and other factors to think about.    

Average weight for girls

According to the CDC, most 13-year-old girls weigh between 76 to148 pounds (lb).

The 50th percentile for weight during this group is around 101 lb. this suggests that about 50% of women this age weigh but 101 lb.

If a 13-year-old girl weighs under the fifth percentile, then a doctor may classify this as being underweight.

If a 13-year-old girl weighs above the 95th percentile, then the doctor may diagnose obesity. However, height comes into play, too.

Here are the percentiles by weight for 13-year-old girls:

Percentile               Weight

5th percentile         76 lb

10th percentile       80 lb

25th percentile       89 lb

50th percentile       101 lb

75th percentile        116 lb

90th percentile        135 lb

95th percentile        148 lb

Average weight for boys:

According to the CDC, most 13-year-old boys weigh between 75/145 lb.

The 50th percentile for weight during this group is around 100 lb. this suggests that fifty of 13-year-old boys weigh but 100 lb.

If a 13-year-old boy weighs under the 5th percentile, then a doctor may categorize this as being underweight.

On the opposite hand, if a boy during this age bracket weighs quite the 95th percentile, the doctor may diagnose obesity. However, they take height into consideration.

Here are percentiles by weight for 13-year-old boys:

Percentile                   Weight

5th percentile           75 lb

10th percentile         80 lb

25th percentile         88 lb

50th percentile         100 lb

75th percentile         116 lb

90th percentile         133 lb

95th percentile         145 lb

What is BMI?

BMI may be thanks to estimating body fat percentage. The calculation incorporates weight and height. A high BMI can indicate high amounts of body fat. It also can indicate an increased risk of weight-related health issues.

For a more accurate assessment of body fat, an individual can check out skinfold measurements, underwater weighing, and bioelectrical impedance. However, these tests could also be complicated and expensive, and therefore the results tend to correlate well with BMI.

The calculation of BMI is different for adults and youngsters. In children and teenagers, BMI takes age under consideration, and doctors ask it “BMI for age.”

The CDC provides a BMI calculator for youngsters and teenagers. an individual enters the child’s height, weight, and sex. The results give the BMI and indicate whether the load is during a healthy range.

BMI, like average weight, falls into percentiles. These can help parents, caregivers, and pediatricians determine whether a toddler weighs a healthy amount for his or her age and height.

Percentile                                                   Assessment

Under the 5th percentile                    Underweight

5th to 85th percentile                              Healthy weight

85th to 95th percentile                      Overweight

95th percentile or over                     Obese

BMI in adults


BMI in metric units, use the subsequent method: BMI = kg/m2

So, calculate an adult’s BMI: Divide their weight in kilograms (kg) by the square of their height in meters (m2)

Since most of the people measure height in centimeters (cm), divide height in cm by 100 to urge height in meters.


When using imperial units, use the formula is: BMI = lbs x 703/in2

 Multiply a person’s weight in pounds (lbs) by 703. Then divide by their height in inches, squared (in2)

What factors control the average?

The average weight of 13-year-olds is trickier to pin down. That’s because a variety of things can influence weight for young teens.

Rate of development

Children enter puberty sometime between 8 and 14 years old. If you’re taking a sample of 13-year-old kids from an equivalent room, you’ll see a good range of body sizes and weights. Some kids may have finished the method while others are just starting to undergo the various changes that cause physical maturation.

Height and body makeup

Your child’s height can also influence their weight. Taller kids may weigh quite shorter ones, but that’s not always the case. Bone density and muscle mass are important factors. There are many variations in body composition. Since muscle weighs quite fat, for instance, a toddler who is more muscular may weigh quite a toddler who is leaner or one who has more fat in situ of muscle.


While diet and activity levels play a task, body shape and composition also are influenced by the genes children inherit from their parents. In other words, people from different genetic backgrounds often have different fat distributions systems. Different body compositions which will inherently influence body shape, size, and weight.

Genetics, also as lifestyle characteristics, like diet and physical activity, play a task during a child’s weight and somatotype.

Body composition

The many variables during a person’s body composition can influence what proportion they weigh. for instance, some people are more muscular, and that they may weigh more because muscle weighs quite fat. This might particularly affect athletic children.

Also, taller children are likely to weigh quite shorter children, although this is often not always the case. Because the BMI calculation takes height under consideration, it can provide a better idea of healthy ranges than weight alone.


Even where a toddler lives may influence their body size, height, and weight. This has got to do with a variety of things, including access to food, socioeconomic level, cultural practices, genetics, and other factors, just like the onset of puberty Trusted Source, which may vary by geographic location around the globe.

Body mass index

Body mass index (BMI) takes under consideration quite simple averages with reference to weight. it’s typical for calculating body fat percentage using height and weight without skinfold measurements or other more direct methods, like water weighing. With teens, BMI calculations also think about age and sex, what’s mentioned as “BMI-for-age.” This figure shows where your teen lands on the spectrum of other kids an equivalent age.

To calculate your child’s BMI, use this calculator Trusted Source provided by the Centers for Disease Control and Prevention. You’ll enter your child’s age, sex, height, and weight, from which you’ll get a result indicating if your child is underweight, overweight, healthy weight, or obese.

Less than 5th percentile                              underweight

5th percentile to 85th percentile                  healthy weight

85th percentile to 95th percentile              overweight

95th percentile and greater                            obese

Why is that this information important?

Kids who fall under the overweight and obese categories could also be at a better risk of developing type 2 diabetes, high cholesterol, or other weight-related health issues. That said, BMI isn’t always the foremost accurate measure, since it doesn’t take into consideration muscle mass or other factors that may affect weight, specifically muscle versus fat.
