At what age do horses' legs stop growing?
I interpreted the "string test" for eventual height (piece of string from fetlock to elbow, swivelled from elbow to above withers, gives final height) to mean that after about a year horses' legs don't grow much. At the moment Charlie's front legs are about a hand shorter than Mattie's, and Mattie is 15.2 or 15.3, so I would guess from that that Charlie will make about 15hh. But one of my fellow liveries said "he's going to be tall, he'll make 15.2 easy" and I thought "not if his legs don't grow" and am now very confused.
Is there a way to know? Or no real rule of thumb?
