What size microwave should I buy?

Reviewers tie capacity to turntable size: roughly 0.9 cu ft for apartments and dorms, 1.1–1.6 cu ft for most households, and 2.0+ cu ft for large dishes. Community reviewers note a 12.4-inch turntable comfortably fits dinner plates and large bowls, while compact 10.6-inch trays handle a single 10-inch pizza.
