I needed this info yesterday and wasn't able to find it online, so I went home and recorded all of the map tile dimensions (in inches). Figured I'd share, in case any of you were trying to devise a storage solution for the map tiles. I ended up using a case logic 72-CD book (tall). All but 3 tiles fit nicely in there, and I don't have to fumble for minutes through a freezer bag...
Here it is (dimensions in inches, each line is the tile number and both side dimensions - multiples of tiles are also listed, so there is a complete count):
