14.2 is perfect for me.
I'm five feet tall with short
legs. I'm heavy for my size, so it's hard to find a little thang that built well enough to carry me.
My own horse is 15.3! She's way too tall for me. She has to park out pretty far for me to mount from the flat. I cannot for the life of me jump on her bareback. My legs are so short I have to ride with too long stirrups to cue her properly.
