Buying Guide
Key considerations when shopping for a 20-inch class over-the-range microwave include width vs. interior capacity, venting options, and the availability of practical presets. If you need built-in ventilation, models with integrated hoods can save space and simplify installation, but confirm duct routing and clearance in your cabinet layout. For compact spaces, prioritize interior capacity that can handle common dishes without crowding, and examine turntable size to ensure it fits your largest plates.
- Ventilation type: Integrated hood vs. outside venting. Integrated vents save space but require proper ducting and clearance.
- Power and presets: Look for at least 1000 watts and presets for popcorn, defrost, and beverages for quick meals.
- Cabinet compatibility: Verify width, height, and mounting requirements for your specific cabinet opening, especially for 20-inch or near-20-inch spaces.
- Interior space: Aim for at least 1.2–1.7 cu ft to fit common containers and plates without crowding.
- Durability and serviceability: Choose models with widely available replacement parts and familiar control layouts if you value easy maintenance.
