Planning this size
Planning a 30×40 trade show booth
At 1,200 square feet, plan the booth like a small building: meeting rooms, storage, a hospitality area and a stage, with clear routes between them. Double decks need show approval and engineering sign-off, so start early.
Only builders with large-island experience list this size. A 30×40 rental is a common choice for exhibitors who show at this scale once or twice a year.
