I hve a stocky 14.3 paint mare, and she carries me just fine and I don't look to bad on her, and I'm 5'9 at 150, but thing is I'm not to leggy, more then normal sense my height, but she has a good thick build, I also ride a 15hh QH, 15.3hh palamino and a 16.2 paint, paint and pally are leggy, the paint more so, but they both work good for me too. I ride trails, that's about it lol but I am showing my mare in 4H and everyone says we look good together. Now if you want to talk looking big on a horse, then that would be my 6'6 boyfriend, who had indeed ridden my mare around at a walk, he looks HUGE on her lol he is so lanky that he wouldn't be able to do much more then ride her around the field or a trail. And that's why my 16.2hh Missouri Fox Trotter paint is in training lol he is tall enough for my bf to not look like a giant.
