hey guys, i'm making a presentation in keynote that is going to be projected on a 22'x20' screen. my questions is: what slide size should i use to make sure i get the best resolution out of my presentation. right now my slides are 1024x768 but because i don't know what that means in feet or inches i'm confused. what are the units used to measure slide sizes and have anyone made presentations for projection that can help me suggest the proper slide size? thanks in advance.
