I'm 15 & 1/2, I barely started my period when I was 15 & i'm 5'8, when am I going to stop growing?
There is no set or definite amount in which you will stop growing. This is because, the growth time for every girl differs on various factors. These factors include hormone or genetic order thus, you will have to observe yourself closely.
People usually stop growing in highschool.
On average girls stop growing by 18. I've been my current height (a big 5'2") since i was 12 years old. So basically there's no telling.
