A:AnswerA 13.3" laptop will fit, but I wouldn't suggest it. If you want a laptop sleeve to be effective in protecting your equipment, you should make sure that it fits snugly and has little or no room to move around in it's case or sleeve. I would purchase a sleeve that is made for laptops that are no bigger than 14" and one that is made for your laptop (i.e. 13.3 inches) would be the best option. Hope that helps.
