SHOW ME YA MOVES!
Miyamoto stated in a recent interview that Link is 9 and 16 in OoT, but he did not provide a comment on TWW Link (the Toon Link trophy in SSBB says he's 12 in TWW though).
Link's age in OoT is all over the place, from 7 to 10. The official Nintendo guidebook I had said 10, though, so that's just what I go with.
