What size griddle should I buy?

Across the reviewers we read, 28 inches is the most-recommended size for a family of four to six, offering enough room to stage cold and hot zones without dominating the patio. 36-inch models are favored by people who routinely cook for groups of eight or more, while 17–22 inch tabletop units are the consensus pick for camping, tailgating, or apartment patios.
