[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]Growth plates close at bone age 16. But some kids hit bone age 16 at 14 or 15 years old and some don't hit it until 18 or 19.

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

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.[/quote]

Sorry; I guess I wasn't clear.

Growth plates close at [b]BONE AGE 16[/b]. 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.

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.[/quote]
