What size griddle should I buy?

Reviewers and r/blackstonegriddle community threads broadly suggest a 28-inch (two-burner) griddle as the sweet spot for most families, offering enough surface for a crowd while still being storable. Choose a 17- or 22-inch tabletop model if you camp, tailgate, or have limited space, and step up to a 36-inch four-burner unit only if you regularly cook for large groups.
