How to type up notes that will print and fit onto a 3X5 note card using Microsoft Word? 10 pts!?

I am allowed to use a 3X5 note card, double sided, to take notes on and use for tests. I am a bit weary from writing so small, so I want to type up my notes and have them fit PERFECTLY onto the note card. Do I have to move margins around to get this done? Please give me step by step instructions if you know how to do this! Thank you! I have Windows 7, if that means anything!
