I probably shouldn't post this because you are asking a specific question...but I just gotta
. I would not pass up on a really good horse, no matter his size. As long as the horse has no problem carrying you...the heck with what people think. In my area, there are so many people willing to pass a horse off to you no matter your riding level or experience. When you actually find a good one, it is very much like striking gold.
My sister has a guy that is 14.2 hands. My nephew rode him the other day with nothing but a halter and lead rope (made into makeshift reins). The funny thing is, most people look fine on him...it's his build.
