Depends on how long your torso is. I'm 5'1" with a really long torso and I just barely fit the 13.2 pony I lease, weight wise I'm no problem, but I just look award. 14.1-15.2 works good for me, I can't have a horse with a big barrel though, because my legs are too short. It depends on your body shape :)
Thanks, unfortunately I have to put my mare down that I've had for 9 years. I've been looking for a new horse for awhile now but it feels like its too soon to look but then again this is an offer I can't pass up. It's not often that you find a Fjord in NY.
