The interior of a 27-inch KitchenAid wall oven is 19 inches deep, 18 inches wide and 22 inches high. The oven capacity is 4.3 cubic feet, which KitchenAid states can accommodate a large turkey, a roast or multiple dishes as one time.
KitchenAid manufactures single and double 27-inch wall ovens. Most models offer Even-Heat True Convection, but the double wall oven models feature True Convection in either the lower or the upper oven. Other KitchenAid ovens feature an Even-Heat Thermal Bake/Broil setting. As of 2015, KitchenAid ovens have a special temperature probe that measures the internal temperature of food without requiring the user to open the oven door.
