By height? No wait, that's something different. :D

Seriously though, I think you define a good guitarist by how he plays. Some people play minimal notes but they can make the hairs stand up on the back of your neck. Others shred with such speed and precision that it's almost frightening to watch. Overall, a "good" guitarist is the one who can make the music come alive no matter how he/she chooses to play.
