I took his hard to see boots into consideration with the lines. That said, I found a brighter video and got a picture of them:

Being able to see Link's boots a lot more clearly and factoring in both Link and Ganondorf's heights if standing up straight, he's more like 3/4 the height which would make them 5'6 and 7'4 (going by the guess of Link being 5'6).
That's more believable. His knees are still bent, though, so I would say Link's about 5'7'' or 5'8''. (Like me! =D)
