Open-state footprint
Will this appliance fit under the cabinets?
The body might. The lid, basket, door, steam plume, air intake, hot exhaust, cord, and your hands may have other plans.

Do not borrow space around one air fryer or cooker for another. Measure the intended location, including backsplash, cabinet trim, outlet, and where the appliance moves during loading.
