The size of the microwave that can fit a large plate depends on the diameter or diagonal measurement of the large plate. Microwave ovens come in various sizes, typically measured in cubic feet or liters, and their internal dimensions can vary.
As a general guideline, a microwave with an interior capacity of around 1.5 to 2 cubic feet (42 to 57 liters) or larger should be able to accommodate most large dinner plates, which are typically around 10 to 12 inches (25 to 30 centimeters) in diameter.
Keep in mind that microwave sizes are categorized based on their internal capacity, so it's essential to check the specifications and dimensions of the microwave's cooking chamber rather than just relying on the exterior dimensions. When purchasing a microwave, consider bringing your large plate with you to the store or check the interior dimensions online to ensure it will fit comfortably inside the microwave.
Additionally, if you have a turntable in your microwave, make sure that the diameter of the turntable is large enough to accommodate your large plate without hitting the sides of the microwave's interior. Some microwaves also have rectangular or oval-shaped cooking chambers, which may be better suited for larger plates than microwaves with round interiors.
In summary, look for a microwave with an interior capacity of around 1.5 to 2 cubic feet or more and check the dimensions of the cooking chamber to ensure that it can comfortably accommodate your specific large plate.
