I'm still a noob with photoshop (PSE6) and I need your help please. I am trying to print out some note cards that I designed. I have stationary that I purchased that is 5.5" x 8.5 (half of a normal document). What setting do I use in the page set up to select this size paper? I don't see anything that specifically says these measurements but alot of them have A4, A3, etc and I don't know what those mean. I'd sure appreciate any help I can get. Thanks!
