I like this size for playing in whole group, it's easier for everyone to see the cards that are drawn out. I wanted something smaller for small groups of students to play or for individual students to play at their desk, but didn't want to re-create the whole file again. So, I found out that you can print multiple pages onto one page, the printer reduces the size of the graphics/words to fit. YAY! All you have to do is go to your print settings under page size and handling and select "multiple", then choose "pages per sheet", take a peek at your preview and see if that size works for you.
Those are the steps for my particular printer, but I'm sure you'll find a similar setting for most printers. Enjoy!
