The average height for a 17-year-old boy is around 175.5 to 175.8 cm (about 5'9"), with most falling between 163 cm (5'4") and 180 cm (5'11"). This varies by genetics, nutrition, and location, but it's a common age where growth slows, though some might still grow taller until 18-21.
The average height of a 17 year old boy is between 170cm (5'7'') and 178cm (5'10'').
At age 17, your son is about to start the last stage of their adolescence, that phase between childhood and adulthood. But they are still growing -- literally. Males keep getting taller into their early 20s. Here are some other things you can expect as your teen crosses the final threshold into manhood.
The average height of a 17-year-old boy is 5′9.1″, so you're a little shorter than the average for your age. There is no reliable way to accurately predict how tall a person will eventually be. At 17 and male, you are probably at or nearing the end of your growth period.
5'7" is pretty short in the US. Per CDC data it is at the 24th percentile for adult males.
Ideal mates
A “standard man” was described as weighing 70 kg (154 pounds) and being 170 cm tall (5′7″). This individual would end up with a calculated body mass index (BMI) of 24.1 kg/m2.
The average height for men in the United States is 5 feet 9 inches. That number continues to change based on ethnicity, genetics and other factors. Non-Hispanic Black men in the U.S., for example, are, on average, 5 feet 9.3 inches tall, while Mexican-American men are, on average, 5 feet 6.9 inches tall.
A height of 120cm typically corresponds to children around 5 to 8 years old, depending on the brand and individual growth, often fitting into sizes like 6 years, 6-7 years, or 7-8 years in children's clothing, but it can vary significantly, with some 5-year-olds hitting this height and some 8-year-olds still growing into it.
When Do Growth Plates Close? Growth plates usually close near the end of puberty. For girls, this usually is when they're 13–15; for boys, it's when they're 15–17.
Stunted height growth is primarily caused by severe malnutrition (especially protein, vitamins, minerals) and chronic illness during childhood, but also by hormonal issues (growth hormone deficiency, thyroid problems), genetic conditions, extreme stress/neglect, and certain medications like long-term corticosteroids, all impacting the bone growth plates. While genetics set your potential height, these environmental and health factors prevent you from reaching it, especially if they occur during the critical first 1000 days (conception to age 2).
Adult height is influenced by genetics, nutrition, and habits, with the human growth hormone released during sleep playing a crucial role in development. While quality sleep is vital for health, no direct link between sleep quality and adult height has been established.
The nutrients that support height growth include the following:
Changes in Boys
The growth spurt of boys is, on average, about 2 years later than that of girls. By age 16, most boys have stopped growing, but their muscles will continue to develop.
Add the mother's height to the father's height in either inches or centimeters. Add 5 inches (13 centimeters) for boys or subtract 5 inches (13 centimeters) for girls. Divide by 2.
“Short King” isn't just a meme — it's a movement. A shout-out to every man under 5'8” who carries himself with pride, confidence, and charm that towers over any height chart. These men don't measure worth in inches.
In this database, a 95th percentile male is 6 feet, 2 inches (188 cm) and 246 pounds (111.58 kg); a 5th percentile female is 4 feet, 11 inches (150 cm) and 113 pounds (51.26 kg).
Scientists estimate that about 80 percent of an individual's height is determined by the DNA sequence variations they have inherited, but which genes these changes are in and what they do to affect height are only partially understood.
Lack of height change over time: If you haven't noticed an increase in height for over 1-2 years, it's likely that you've stopped growing. Maturity in physical appearance: Your body will look more adult-like, with features such as facial hair in males or fully developed hips and breasts in females.
The upper age limit for starting GH therapy is generally determined by the status of the growth plates (epiphyses) in the bones. Once these plates close—typically around age 14 in girls and 16 in boys—further height increase is not possible.
A weight of 70kg can fall within the healthy weight range for various individuals. Height plays a significant role. A shorter individual might find a BMI of 70kg within a healthy range, whereas a taller person could potentially fall into the overweight or even the obesity category using the same metric.
Sleep deprivation has long been linked to an increased risk of becoming overweight or obese. Researchers found that getting less than seven hours of sleep resulted in weight changes and may lead to weight gain, either by increasing food intake or decreasing energy burned.
For adults ages 20 years and older, BMI incorporates weight and height, but it does not take age or sex into account. A woman tends to have more body fat than a man with the same BMI. Likewise, an older person tends to have more body fat than a younger person with an equal BMI.
