The real limit: length, not width

Centred in this room, the table's width (38 in) leaves plenty of room side-to-side — the tight dimension is length against the 12 ft wall. Every extra 12 inches of table length costs 6 inches of clearance on each end. A 10 × 12 room comfortably fits up to about a 66–72 inch table for six chairs; going to an 84-inch table for eight starts pushing at least one side below the 91 cm "normal circulation" target used here.
