Footprints vary by model; example dimensions from listings include compact sizes such as 13.3" H x 11" W x 13.6" D and larger toaster-oven footprints like 10.67" H x 19.45" W x 15.28" D.
Capacities span small countertop air fryers up to large ovens. Examples in the selection range from about 4 quarts to 14 quarts and even a 37-quart oven.
Many appliances use digital controls or touchscreens and include one-touch cooking presets or guided presets to set time, temperature and cooking functions.
Common accessories include air fry baskets, oven racks, baking pans and crumb trays. Some larger units also list rotisserie spits, lift tools and additional baskets or drip trays.
Review summaries describe 4-quart and similar small footprints as countertop-friendly and a good fit for singles or couples, while 14-quart (and multi-rack) ovens are repeatedly noted as suited for family-sized meals.
