Visible signs of puberty & height growth

[Anonymous]

Once a boy has significant armpit and body/leg hair, is his major height growth spurt done? Meaning, perhaps he'll grow another inch or two but that's probably about it?

Asking about what is typical; I know there can be wide variations. Thanks!

Those aspects of puberty (e.g., body hair that's not pubic hair, voices dropping) are unpredictable in timing and aren't pubertal "milestones", like the way Tanner staging is. So where they fall in a boy's pubertal growth is really all over the place.

My DS grew in college.

The voice change is not totally random and I've read multiple places when their voice has fully dropped they've finished their major growth spurt. This makes sense if you think about it. Part of what is going on is their larynx is physically growing. I do think voice change can be rather quick or take longer.

There are also things like this...

When the voice change of a boy has begun, the growth spurt is in its most intensive phase. When the voice has acquired adult characteristics the growth rate has begun to decelerate.

For my son, the leg hair growth was late. But we are very fair and not that hairy in general.

is there any correlation between the timing of facial hair/beard and the end of growth in height?

I believe armpit hair/body hair varies quite a bit and is not an indicating factor….

My 14yo DS is in a period of rapid growth (4in+ in the last 12 months) and only has a few wispy underarm hairs- not really noticeable. He is fair skinned/light hair and I think that makes a difference. No voice change either. Per ped, early signs of puberty were present a year or two ago (can’t remember exactly).

I’m pretty sure the ability to grow an actual beard means height growth is about done.

OP here, nope, my son hasn't even started this phase yet!

This would be evidence of the premise being true - big growth spurts precede the body hair growth.

I’m very curious too, as my son is mixed race and won’t get much leg or pit hair.

MY DS has had two major growth spurts. Has developed leg and underarm hair but no arm or chest hair. Does it normally start lower body then upper?

But you are already paranoid

My son is 15 and no armpit hair. Voice is still changing (cracks) and some hair on lower legs. Grew 3 inches last year.

My DS’ voice changed pretty fully years before he was close to being done growing height-wise. A think there is a lot of variation.
