Girls generally reach their maximum height at 14 or 15, while boys may keep growing until 16 and likely show the most growth between 12-15. However, when monitoring your child’s development it’s not so much about comparing them to specific percentiles but more ensuring that they are consistently progressing in age-appropriate ways.
There are cases where people hit their peak height slightly earlier or later than the average age range mentioned above; this is due to a variety of factors including the age of puberty onset, nutrition, genetics, and lifestyle habits.
What Causes Growth Spurts in Teens?
Growth spurts are generally caused by an increase in hormones such as testosterone and estrogen during puberty. The hormonal changes cause bones to grow faster than usual which results in a rapid increase in height over a short period of time. In addition to hormones, good nutrition and adequate sleep can contribute to healthy growth spurts. Eating nutrient-dense foods like fruits and vegetables can help provide the necessary vitamins and minerals for bone development while having regular bedtimes can help ensure that your teen gets enough rest for optimal growth potential.
Can You Affect Your Final Height?
While you cannot change your genes or alter your genetic makeup, there are certain lifestyle changes you can make that may affect your final height such as eating nutritious foods, exercising regularly, getting adequate sleep each night, avoiding smoking cigarettes or drinking alcohol excessively (as both of these substances can stunt growth). All these things combined with starting puberty at an appropriate age should result in healthy growth for your teen over time!
Conclusion:
Understanding when teens will stop growing is an important question for many parents out there. While most teens will hit their peak height within the average age range cited above (14-17 years old), there are other factors such as puberty onset age, nutrition, genetics and lifestyle habits that can affect final adult height as well. By ensuring that teens get enough nutrients from their diet and making sure they get plenty of rest each night (in addition to avoiding substances like cigarette smoke or alcohol) parents can help ensure their teen has the best chance at reaching their maximum adult height potential!
