What size pressure cooker should I buy?

Reviewers consistently map size to household: 3-4 quart models suit singles and couples, 6 quart is the most-recommended all-rounder for families of three to five, and 8 quart-plus is favored for batch cooking and large cuts of meat. Verified-purchase reviewers note that bigger pots take longer to come to pressure, so don't size up unless you actually cook in volume.
