Use the function on your printer to "fit to printable area" and it will come out perfect for a three ring binder or the perforated rings.
Absolutely. Good for old folks like me that need large print.

But, I am looking for the classic old rule book size, to bind with a wire spiral binder, as I've done for many, many years now. Ain't gonna get it, though, unless I shrink the book artificially, to fit. Then the text gets unacceptably small. So, it looks like it will be about a 6" x 8" booklet (with text at the default print size). I am really curious what size the printed books will be. We'll see in July, I guess.
