Teenagers’ Average Weight Vs. BMI
BMI, also known as Body Mass Index, is a very common measure for assessing an average healthy body. The formula to measure your BMI is very simple. What you need to do is to divide your weight by your height squared. According to the CDC (Centers for Disease Control), using a BMI calculator is a good way to screen for a healthy weight, underweight, overweight, or obese.
But it should be noted in mind that BMI is not considered as a diagnostic tool. So, even when your teenager has a lower BMI than the recommended range, it doesn’t mean he/she is underweight. A health care provider might do other professional diagnostic tests to give the final results if your teen is underweight or not.

Typical Teen Bodies
As a parent, you might know that your teenager’s body is substantially affected by puberty. Even though the above charts show the average weight and height for teen boys and girls, this story is much more than that. Pediatricians usually have charts with weight, height, and BMI for each age and percentile. So, if your teen is far off this graph, you should visit his/her doctor. He/she sees different teen bodies. As such, they have a far healthier appreciation for what “average/normal” is.
But here are some important things you should note to follow your teen’s growth more conveniently.
- Hormones can start to change the structure of the body. As such, even if normal development takes place, a teenager’s body will start to look very different. These variations might worry your teens because they can lose their narrow and straight childlike bodies. While boys are worried about looking more masculine, girls worry about the curves. Usually, the actual weight and height of teens will have a difference, more or less.
- All teens (both girls and boys) will go through a period, which lasts around 2 years, of fast height growth. Before this happens, the body might seem to be heavier. And after the growth spurt, their bodies start to lengthen, even appearing too thin. For boys, this stage of development typically occurs between the age of 12 and 16 years old. However, for girls, it is usually earlier, from 10 to 14 years old.
- While a teen boy’s body fat percentage will naturally decrease, that percentage for a girl is typically increased. It should be noted that genetics play a crucial role in how this happens.
- During puberty, boy has a growth spurt and they are depend on different ages. In this period, boys often grow approximately 3″ within a year.
However, you should talk to your teenagers about weight and body image and what’s healthy instead of thin versus fat. Let them know that there is no one ideal weight and height that is suitable for everyone. Also, teach them to value and take care of their bodies.
