Learn when boys and girls usually stop growing taller, what growth plate closure means, and how to tell whether your child’s height growth may be slowing down or finished.
Answer a few questions to get personalized guidance on signs height growth may be slowing, when teens often keep growing taller, and when it may help to check in with a clinician.
Height growth usually slows and stops after puberty, but the timing is different for every child. Girls often stop growing taller earlier than boys because puberty usually starts earlier. Many girls grow most quickly before and around their first period, then continue to gain some height for about 1 to 2 years afterward. Boys often keep growing later into the teen years, with growth slowing after their main puberty growth spurt. Parents searching for when does height growth stop in boys, when does height growth stop in girls, or what age do kids stop growing taller are usually looking for a range, not one exact age. A child’s puberty timing, family growth pattern, nutrition, sleep, and overall health all play a role.
Girls often stop growing taller around ages 14 to 15, though some finish earlier and some later. Height growth usually slows after the first period and may continue a little longer.
Boys often stop growing taller around ages 16 to 18, though some continue later. Because puberty often starts later in boys, their growth spurt and final height timing can also come later.
Early puberty, late puberty, and family growth patterns can shift the age when height growth stops. A child who starts puberty later may keep growing taller longer than peers.
If your child has had hardly any change in height over the past year, it may be a sign that growth is slowing significantly, especially in the later teen years.
When major puberty milestones have already happened and development seems to have leveled off, height growth may also be nearing its end.
Parents sometimes notice fewer size changes along with slower height gain. This does not confirm growth is done, but it can be one clue when combined with age and puberty stage.
Growth plates are areas near the ends of bones where growth happens during childhood and adolescence. When growth plates close, bones stop getting longer, which means height growth is finished. Parents often ask when do growth plates close, but there is no single age that applies to everyone. Growth plate closure usually happens after puberty is nearly complete and tends to occur earlier in girls than in boys. Doctors do not usually determine this from guesswork alone. If there is a medical reason to check, a clinician may use growth history, puberty history, and sometimes imaging to better understand whether growth is still possible.
If a child appears to stop growing taller well before peers and before puberty seems complete, it may be worth reviewing their growth pattern.
A child who used to grow steadily but now has almost no height change may benefit from a closer look at timing, puberty stage, and family history.
If you are unsure whether your child’s growth pattern is typical, an assessment can help you understand what is common, what signs to watch, and when to speak with a clinician.
Girls often stop growing taller around ages 14 to 15, but the exact timing varies. Many continue to grow for about 1 to 2 years after their first period, though the amount of height gained is usually smaller than during the earlier puberty growth spurt.
Boys often stop growing taller around ages 16 to 18, but some continue later. Because boys often enter puberty later than girls, they may keep growing taller for a longer period during the teen years.
Teens usually keep growing throughout puberty, with the fastest growth happening during the main growth spurt. Growth then slows as puberty progresses and eventually stops when growth plates close. The total length of time varies based on when puberty begins and how quickly it progresses.
Parents often notice very little or no height change over 12 months, especially when puberty changes are mostly complete. That can suggest growth is slowing or done, but it does not confirm growth plate closure on its own.
Growth plates usually close after puberty is nearly complete, often earlier in girls and later in boys. There is no exact age that fits every child, which is why doctors look at the full growth and puberty picture rather than age alone.
