Most toaster ovens list core functions like bake, broil and toast, plus keep-warm. Many models also include convection, air fry, roast, dehydrate and reheating or preset modes such as bagel and pizza.
Typical toaster-oven dimensions fall roughly between 8.6 and 14.5 inches tall, about 14.5 to 18 inches wide, and about 11.2 to 18.5 inches deep. Expect a footprint in that general range, though exact size varies by model.
Toaster ovens in the results use roughly between 1,150 watts and 1,800 watts, depending on model and features.
