Why clearances matter for countertop microwaves
Every microwave manufacturer publishes required clearances — the minimum breathing room needed around the unit for safe operation and to prevent voiding the warranty. A typical countertop needs 3" on each side and 3" above, so a 20"-wide unit needs a 26"-wide space. MicrowaveFit calculates this math automatically for every model on this page.
Use the dimension filters above to find every small countertop that fits your exact space — clearances included.
