A:Answer There's only about 1 1/2 inches between the two rack grooves. Not a lot of space between them for cooking if you were to get a second rack -- maybe cookies? With the rack in the bottom groove, you've got about 4 1/2" to the 'ceiling.' Using the basket rack that comes with the oven, you'll add another inch of room. (13"w x 12"d for the oven cavity) Hope this helps.
