What Counts as a “Big” Countertop Microwave (Cu Ft)

How many cubic feet is big for a countertop microwave?

For a countertop microwave, “big” typically starts around 1.3 cubic feet and up. That size range is noticeably roomier than compact models and is designed to handle larger plates, wider bowls, and many family-style leftovers without forcing you to angle the dish or heat in batches.

As a quick way to think about it: 0.7–0.9 cu ft is compact, 1.0–1.2 cu ft is a comfortable everyday middle ground, and 1.3–2.2 cu ft is where countertop microwaves start feeling “large.” Many of the biggest countertop units fall around 1.6–2.2 cu ft, which can be great for busy kitchens, shared households, or anyone reheating larger portions frequently.

What “big” means in real use

A larger cubic-foot rating usually translates to a bigger turntable and more interior height/width, which matters for items like oversized dinner plates, casserole dishes, and multi-serving containers. If you often heat wide or tall containers, moving up to 1.3 cu ft or more can reduce splatters (more headroom) and make loading easier.

Don’t forget the outside footprint

Bigger capacity also tends to mean a deeper or wider body, which can crowd a counter—especially under upper cabinets. Before buying, measure the space where the microwave will sit, including clearance for ventilation and a comfortable door swing.

How power fits in

Capacity and wattage aren’t the same thing, but they often rise together. Many larger countertop models run around 1000W or more, helping food heat faster and more evenly than smaller, lower-watt options.

FAQ

What size microwave is best for a small kitchen?

A compact microwave around 0.7 to 1.0 cu ft is usually easiest to fit on limited counter space while still handling most reheating tasks. If you regularly use large plates, consider 1.1–1.2 cu ft and measure carefully.
