Smallest Footprint Microwaves

When counter space is at a premium, every inch counts. The models below are 18 inches wide or less — genuinely compact units that fit in tight galley kitchens, RVs, small apartments, and corner counters. Enter your space dimensions above to see exactly how much clearance you'll have after installation.

• ✓ Width is only one dimension — always check height and depth too, especially for under-cabinet clearance.
• ✓ Compact models need the same side clearances as full-size units: typically 3 inches each side. Factor this into your available width.
• ✓ At this size, interior capacity is tight — check the turntable diameter to confirm your plates and bowls will fit.
• ✓ Some compact units are noisier and slower than full-size alternatives. If speed matters, look for 800W+ even in a small footprint.
