I am 5' (5'1" on my tall days)
and my boy is 14.3 my new mare is about 15 h I am guessing (Haven't tested yet) But here is a pic of Me and Romeo.
I have ridden horses up to about 16 hands and when Minnie is rideable I will ride her. (17.2)
This was like 2 weeks after I got him (I was afraid to ride by myself so I had my mom lead me!)
I'm 5'7-8" ish and Lacey is 14.1 or 14.0. Standing next to each other, I look like a giant compared to her, but on her back I look perfectly fine. It's mostly because my height is in my torso, not my legs.
