Best Microwaves for Apartments
Apartment kitchens come in all sizes, but the common thread is limited counter space and no option for permanent installation. The models below are countertop microwaves 21 inches wide or less — practical, portable, and sized to fit without dominating a small kitchen. Enter your exact available counter dimensions above to see fit scores across the full list.
Max width
21 inches
Installation
Countertop — no drilling
Recommended wattage
900–1100W
Best for
Renters, shared kitchens
- ✓ Measure your counter space including the required side clearances — most models need 3 inches on each side for ventilation.
- ✓ If you're renting, avoid OTR models entirely — they require wall mounting and drilling that most landlords won't allow.
- ✓ A 1.0–1.2 cu ft capacity handles everyday apartment cooking without taking over the counter.
- ✓ 1000W is the minimum worth paying for — anything less heats unevenly and slowly, which gets frustrating fast in daily use.
- ✓ Consider where the door swings — a right-hinged door opening into a wall or cabinet is a common frustration in tight apartments.
