Synopsis
This reference chart presents average height and weight measurements for male adolescents aged 13 through 20 years, drawing data from trusted health organizations including the World Health Organization, the National Institutes of Health's Gerontology Research Center, and the U.S. Centers for Disease Control and Prevention. The tool serves as a practical guide for parents, healthcare providers, and teenagers tracking typical growth patterns during puberty and adolescence, when boys experience rapid physical development between ages 11 and 17. By providing both metric and imperial measurements in an accessible table format, the chart helps families and medical professionals identify general growth trends while recognizing that individual variations in body type, muscle mass, and maturation rates are entirely normal. This resource proves particularly valuable for families managing developmental concerns, growth-related medical conditions, or those simply seeking reassurance about whether a teen's physical development falls within expected parameters.At a Glance
- 1 - Boys generally start puberty around age 11 to 12 and finish around 16 to 17, with growth spurts during this time happening faster than at any other point in their lives.
- 2 - By the time a teen boy reaches 18, his height has typically about doubled compared to when he was 2 years old.
- 3 - The average measurements climb from 100 lb. and 61.5" at age 13 to 155 lb. and 69.7" at age 20, with dieting not recommended since boys often simply grow out of "baby fat."
Topic Definition
- Teen Boys Height Weight Chart
A teen boys height weight chart is a reference table that sets out the average height and weight expected for male adolescents at each age, here covering 13 through 20 years. Rather than laying down a target every teenager must reach, it draws averages from large population studies so parents, teens, and healthcare providers can see roughly where an individual sits next to his peers. These years capture the heart of male puberty, which usually runs from about 11 to 17 and brings growth spurts faster than at any other point in life, along with rapid swings in weight, height, and internal development. Since body type, muscle mass, and maturation rates vary widely from one boy to the next, the chart works best as a general guide for tracking steady, healthy growth over time - and as a starting point for a conversation with a doctor who can weigh the numbers against a teen's complete health picture rather than a reason to diet or worry.
Overview
What to Expect as Boys Grow Through the Teenage Years
The weight-to-height ratio measurement in teenage males serves as just a single factor in assessing whether their weight aligns with a healthy average for their height. However, this measurement does not consider individual variations in body types and muscle mass. Its primary function is to provide a recommended range of body weight that is considered ideal for male teenagers.
As boys generally start puberty around age 11 to 12 and end around 16 to 17, teenage boys will often have growth spurts during their growing years in which your body will grow faster than at any other time in your life. During this period, it is possible to gain and lose weight rapidly and add inches to your height - seemingly overnight. Growth not only involves the length and weight of your body, but also includes internal growth and development.
NOTE: If you are older than 20 you will need to refer to our Adults Height to Weight Chart.
| Age | Weight | Height |
|---|---|---|
| 13 Years | 100.0 lb. (45.36 kg) | 61.5" (156.2 cm) |

| 16 Years | 134.0 lb. (60.78 kg) | 68.3" (173.4 cm) |
| 17 Years | 142.0 lb. (64.41 kg) | 69.0" (175.2 cm) |
| 18 Years | 147.5 lb. (66.9 kg) | 69.2" (175.7 cm) |
| 19 Years | 152.0 lb. (68.95 kg) | 69.5" (176.5 cm) |
| 20 Years | 155.0 lb. (70.3 kg) | 69.7" (177 cm) |
Every teenage male is different in how they mature and grow during their teen years. Dieting for male teenagers is not recommended, as quite often you will find boys will simply "grow out" of their "baby fat" as they mature into young adults. Typically, by the time they reach 18 years of age, the height of a teen boy has approximately doubled compared to when they were 2 years old.

Frequently Asked Questions
At what age do most teen boys stop growing taller?
Many boys keep growing into their late teens, often reaching close to their adult height by around 17 or 18. Some continue to add small amounts of height into their early twenties, since boys tend to finish growing later than girls.
Why does my teen son eat so much during his growth spurt?
Rapid growth demands a lot of energy, so a big appetite during a spurt is completely normal. As long as he is active and growing steadily, hearty eating usually reflects healthy development rather than overeating.
Is it normal for a teen boy to gain weight before getting taller?
Yes, many boys put on some weight shortly before a height spurt, then appear to slim down as they shoot up. This uneven, out-of-sync pattern of weight and height is a normal part of puberty.
How can I estimate how tall my teen boy will become?
Parents' heights give a rough guide to a boy's genetic potential, though nutrition, sleep, and health also play a part. A doctor can offer a more precise estimate using bone age and growth history if there are concerns.
Does building muscle in the teen years affect these weight averages?
Yes, strength training and sports can add muscle, which raises weight without adding body fat. This is one reason weight alone can be misleading and why body composition matters more than the number on a scale.
Should I worry if my son is much shorter than his classmates?
Boys enter puberty at different times, so a shorter teen may simply be a later developer who catches up in a year or two. Persistent concern is best raised with a doctor, who can check whether growth is on a healthy track.
Insights, Analysis, and Developments
Editorial Note: Growth during the teenage years remains one of the most variable aspects of human development, with some boys shooting up several inches in mere months while others mature at a steadier pace. What this chart reinforces is that there's no single "correct" trajectory for adolescent development - the ranges provided reflect population averages, not prescriptive targets. Parents and teens who notice significant deviations from these measurements shouldn't jump to conclusions but rather view them as potential conversation starters with healthcare providers who can assess individual health holistically. The real value of this data lies not in creating anxiety about numbers on a scale, but in helping families understand that dramatic physical changes during adolescence are expected, temporary, and part of the natural process of becoming an adult. After all, the teen who feels too short at 15 may well find himself eye-to-eye with his father by 17.
