Height and development for teenage boys
At 17, many boys are still gaining height as their pubertal growth spurt continues. Boys who had a later start to puberty may still have significant height gains ahead. The male pubertal growth spurt typically peaks between ages 12 and 15 and may continue until 17 or 18 for late developers.
The teenage growth spurt for boys
For teenage boys, the growth spurt is often the most dramatic and visible change of puberty. Boys who are late developers should be reassured that their growth spurt is ahead of them, not behind - the final adult height is not determined until the growth plates close, typically in the late teens or early twenties.
Sleep and growth hormone
Most human growth hormone is secreted in the first hours of sleep, making 8-10 hours per night an active contributor to height gains during puberty. Protein needs are higher than at any other life stage to support the rapid increase in muscle mass that accompanies the growth spurt. Iron is also important, particularly for athletic boys.
Frequently asked questions
When do girls stop growing taller?
Most girls reach their final adult height approximately 2-3 years after the start of menstruation, typically between ages 15 and 17. Some girls continue to gain small amounts of height into their late teens, but the majority of pubertal height gain is complete by around 16.
When do boys stop growing taller?
Boys generally stop growing in height between ages 17 and 20, with late-maturing boys sometimes continuing to grow into their early twenties. The growth spurt in boys typically peaks around ages 13-15, later than in girls. Boys who are late developers will often catch up with and eventually surpass peers who grew earlier.
Is it normal to be shorter than friends at this age?
Yes - the timing of puberty varies considerably between individuals. A teenager who is shorter than their peers may simply have a later puberty onset and will often experience their growth spurt after those who developed earlier. If there are no other signs of puberty by age 14 in girls or 15 in boys, it is worth discussing with a GP.
Data sources and methodology
The percentile ranges on this page are drawn from CDC growth chart data from the National Center for Health Statistics and WHO Child Growth Standards (for children under 5). CDC data published May 30, 2000, with 2022 extended BMI tables. Percentiles are modelled using the LMS method (Box-Cox transformation), which accounts for the skewed distribution of measurements at each age. All measurements are given in metric units with imperial equivalents.
For personalised guidance, consult a paediatrician or healthcare provider who can assess their measurements in the context of their full growth history.
