Can boys really be done growing at 15?

It's closely tied to puberty. Testosterone converted into estrogen is what makes bone age advance and growth plates close.

Kids with big constitutional delay aren't having their growth plates/bones closing at 16. All the males in my family had significant growth past the age of 16. And they all gained an additional inch or two in college.

Instead he had a wild growth spurt over a single year and then stopped entirely. Fortunately, he went from very short to above average. His younger brother who was on the tall side (75%) hit puberty around 13. At 15 he appears to be done and it looks like he will be an inch shorter than his brother which nobody expected. It makes me think it’s all about genetics but I do wonder why both stopped growing years earlier than most.

Hormone in dairy, poultry mainly. Eat organic.

Do stretching and jumping exercises. Organic milk, vit D3 and Vitamin K2 MK7. Good nutrition and very good zleep.

However, he is still a skinny string bean compared to his other friends (same race as us). His doctor said in light of that, we can definitely expect at least a bit more growth.

Just depends. DS is 5’11” and probably done growing but a super skinny string bean compared to his friends. DH was the same until he hit middle age, just genetics.

Sorry; I guess I wasn't clear.

Growth plates close at BONE AGE 16. Only an x-ray read by a radiologist and/or endocrinologist can tell you what BONE AGE your child is.

Some kids hit BONE AGE 16 at chronological age 14 or 15 years old. Others do not hit BONE AGE 16 until they are much older.

So some kids will be done growing at 14 or 15, if puberty is far along enough that they have reached BONE AGE 16. But others will grow until 18 or 19, because puberty was later, and they hit BONE AGE 16 at chronological age 18 or 19 or even 20.

I grew 4 inches and gained 20 pounds my freshman year in college. I was 5’3” when I graduated high school, which was considered rather short for a boy. A year later I was 5’7”, which has been my adult height.

I’m pretty sure my 15 year old is done. He grew a ton between 12 and 13 and not much at all between 14 and 15.

My 15.5 ds is still gradually losing a few more baby teeth. Dentist says he won’t get into braces until he’s 16.
My ds does show other signs of puberty - voice changing, hair etc- but wondering if he may have a growth spurt to come.

No. Two of my kids were early teethers and then late bloomers.

Unless they looked at his growth plates.

Yes, it's based on Tanner stage. Usually at the check up for adolescents the doctor notes the Tanner stage.

I have three boys. Anecdotally, most of their friends were done growing right around 16. Some stopped growing more around 14. All three of them were done growing in height by 15-16.

That's for boys. I think for girls they stop growing at an earlier bone age.
It's normal for boys to have a bone age I think up to 2 years lower or higher so yes many boys stop growing at 14. DC has friends who stopped growing at 13.

To clarify looking at growth plates through an X-ray is different from doing a physical check up for Tanner stage but they do correspond really well. That's why they have the Tanner scale in the first place.

DS is 5'9'' with a 5'7'' mom (taller side for women) and 5'8'' dad (shorter side for men). I was like, so is he done? Dr. said close but will probably grow a few more inches. DS immediately asked to go to the store for protein powder (it was a joke). He's almost 14.5

So how much more did he grow, you posted this last year? Just curious.

It does seem unusual they would ALL be under 5'10". It seems there is such a wide range of height at that age. For example, DS' friends' height in his friend group probably range from 5'3" to about 6'3". They are all 14 or 15.

NP here. I thought 5’10” was around average height…is it really considered short now?

5'9" is average height for men in the U.S.

Like most things in life, it seems to vary a huge amount between people.

My dad grew three inches in college.
My brothers hit full height at ages 17/18.
My husband hit full height at 14.
My son was at full height at 13.
My nephew (sister’s son) hit full height at 19.
My nephew (BIL’s son) hit full height at 16.
