Initially bought the 9-11" for the new 10.5" iPad Air, but I optimistically thought it would have some room left to include the case. Unfortunately it did not fit at all. I believe without the case, it will be just right...although the zippers might scratch an unprotected tablet. And it would have been impossible anyway to fit anything bulky in the external pocket. Ended up going to with 13" which can fit the Air encased in a Logitech Slim Combo case with Apple Pen. Space left for the sleeve to expand for other tech gear if necessary. My tip is to really check the internal size of the case, and maybe go up a size or two.
