How much smoker do I need for a family of four?

Reviewers consistently say 500–700 sq in of cooking area handles a family of four with room for full racks of ribs or a packer brisket. The Traeger Pro 22 (572 sq in), East Oak 30" (725 sq in), and Masterbuilt 30" (710 sq in) all sit comfortably in that zone. Larger offsets like the Oklahoma Joe's Longhorn (1,060 sq in) are geared toward gatherings or competition-style cooks.
