Planning this size
Planning a 20×40 trade show booth
Plan a 20×40 trade show booth as two halves: one facing each main aisle, joined by a shared storage or meeting core. A long hanging sign or two smaller ones marks both ends.
Fewer builders list 20×40 as a standard size than 20×20 or 20×30, so send your brief early. Rentals are common, since a structure this size is costly to store.
