Bodey is 15hh and takes a 6ft3 rug, even though really now he is bulking out a 6ft6 would be better around his shoulders, problem is that they are too long in the body then.
My 16hh Luso x TB takes a 6ft. He is quite compact and slim built though.
15.2hh Welsh D takes a 6ft.
13.2hh Welsh X Highland takes a 5'3.
