alright let’s analyse. starting with the gameinformer cover where Link is very clearly taller:
and at the end of champions’ ballad where he definitely has a couple of inches on her:
but then we’ve got the scene from the very end of the main game where it’s reversed:
you could argue that he’s standing ahead of her and Zelda only appears taller because she’s closer to the camera, but it’s the same even in this screenshot where he’s standing behind her:
personally i choose to believe that he’s shorter than Zelda, because Link being a tiny hyperactive idiot is my jam, but i do think that Nintendo’s intention was for him to be taller. they just fucked up at keeping it consistent.
