There are mainly three standard sizes of a photo album. The first one is 4×6 used in the photo fishing industry because its print size mirrors the aspect ratio of most digital cameras. This size is perfect for framed photos, physical backups or cards. A bit larger format is sized as 5×7 and has a slightly higher aspect ratio than 4×6. Simultaneously, the 8×10 image is the largest print size available before getting into large scale printing like panoramas, posters, custom gifts and square images.
