ZeldaWiki has Ganondorf's height, but that's as a human and this image has him as Ganon.
[quote=ZeldaWiki]According to Hyrule Historia, Ganondorf is 230 centimeters tall (approximately 7 and a half feet) in Ocarina of Time. His 1/4 scale model from First4Figures, who used in game data to faithfully recreate his appearance in Twilight Princess, stands at 23 inches tall, which indicates that he stands at 7ft 6 in that game as well.[/quote]
However, OoT Link's figure
He measures approximately 7 inches tall, including the base. If standing tall, he would measure 8.5 inches tall, accurately keeping in scale with current and future statues in the series.
Unfortunately, the site doesn't state the scale Link is at (and he is from a different line to the Ganondorf figure), but if we knew we could calculate Link's height.
As for Pokémon, the tallest is Wailord at 14.5 m (47'07"), dwarfing Ganondorf.
