If you're speaking of my Iwo Jima map (I'm guessing you are...), then it's in 2" format, and don't try to print any map you find in the Carto Thread, instead ask for a high quality version of it for printing. But, I have it in my dropbox in 3" format ready for printing. http://dl.dropbox.com/u/50785043/IwoJima.pdf.zip
(Thinking about it, it might still be 2", but printing at 150% fixes that)
It's printed for 6 2" maps, which would total about 4 3" maps, but not the right size.
If you have any more questions... just ask!
