All of our paper is pre-punched to work with the Rollabind organizational system. We use only high quality 60 pound paper, with a 96 brightness, which means it is softer to write on. These are the dimensions for our paper sizes : lettersize paper measures 8 ½ x 11, junior size paper is 8 ½ x 5 ½. Compact size paper is 4 x 6, and pocket size paper is 2 ½ x 4.
