I purchased this to replace my backpack. It fits everything that I need just perfectly. I have been able to carry two 3 subject notebooks, a sketchbook (5in x 8in). a pencil pouch, wallet, keys, droid, and has space to spare. If you're looking for something for just a few classes, this is the perfect size. If you're looking for something for a huge load of classes and various textbooks, go with a backpack; it would be better on your shoulders and back. I am so happy that I purchased this item!
