I'm only 5'1"( I'M NOT SHORT, I'M FUN SIZED!!!). My share board horse is 16.1. I thought she'd be too big for me, but she's so leggy and slender, she doesn't feel that big. Plus she's got a huge stride, and a trot to die for! I was more comfortable on her than I was on a 14.1hh large pony I tried. Granted, I have several balance issues due to a head injury from a car accident, so the smoother the horse, the more secure I feel.
