A:Answer Well, let's see here. (Gets up, goes to closet, grabs trusty Stanley tape measure from toolbox, measures oven ...) The oven is 18 inches deep from the front of the door to the back of the heat shield on the back. Add 1.5 inches if you want to include the handle. And before anyone else chimes in, here are the rest of the dimensions: Height, 12 inches. Width, 20-3/4 inches. Now I gotta get up and put away the danged tape measure! Geesh, the things I do for you. :)
