Cabinet size restrictions

The average kitchen cabinet’s size controls the maximum size of a microwave that can fit inside it. Do you know the standard depth of a wall cabinet?

The width of the stovetop and microwave should be the same, especially if you are replacing or upgrading the latter. Otherwise, you will notice an unfinished space in the cabinet.

Built-in microwaves

Built-in microwaves are generally installed with a traditional oven inside a 24-inch column or base cabinet. As built-in microwave cabinet dimensions are deep, you can include a large and deep oven as per your requirements.
