I've taken great pains to design all my maps as a pair of 8.5x11 units that print decently onto cardstock. The only drawback is they must be attached at the center, but with a paper cutter, a little patience, and memory of the fact that you can leave a blank 1"+ space on one half to serve as a reception point for the glue, it works out okay.

at 5 spaces by 7 spaces, with 1 inch margins, the standard ED map just about exactly fits on 2 8.5x11 sheets...
