The 17x17 rotary mat is the largest that is made. I have both of the Olfas. If you can only get one I would go with the 17x17. They are good mats. I had a Fiskars non-rotating mat. It was my first cutting mat and it didn't last very long. I've never used their rotating one but if you can afford the larger one I would go with that.
