I can't do it anymore but have training as a graphic artist, making it larger doesn't help some readability issues (such as typeface, contrast and so on).
Yes, it's bigger but it's not as usable unless you have a large surface to write on. And I live in a small town where the print shop is less than friendly/cheap.
Was thinking more along the lines of a character sheet spread out on two pages instead of one. That way I can just keep it on the clipboard I've always used and well, just flip to what I need.
