How to use this list
Every model listed here includes the physical dimensions (what you measure at the store) and the manufacturer-required clearances (the breathing room the unit needs around it). Most sites only show physical dimensions, which leads to returns — a 20" wide microwave needs 20" plus 3" on each side, so your cabinet needs to be at least 26" wide.
Use the MicrowaveFit calculator to enter your exact space and get a Fit Score for each model before you buy.
