35mm x 45mm with white background. Chin to forehead roughly around 25mm. I think you can print about 8 pieces/4R size with small margins between them. Someone did send out some instructions to use PS to put multiple photos on 1 page for printout. Please search for it for more info. I usually use the Olympus Camedia software used by my P&S to print because I can ensure my printout sizes of my photos which I can also select different photos without having to go to PS. Good luck!
