[@PatrickDrummer]average height of a yordle is about two and a half to 3 feet tall (including ears). Rumble is a short yordle at about 2 maybe 1'10". Kled is probably a little over 3 feet tall (with the ears and hat). When mounted he's taller than most champs so I'd bet his lizard is maybe 4 or so feet tall at the saddle five with the head.

I know gnar is around 3'6" and turns around 10 foot tall since he becomes one of the largest champions in the game.

TL : DR I'd say Kled is maybe 3'2" with the hat. 2'6" without it
