While the 40' by 220' canopy tent isn't quite the largest canopy tent available on the market, its towering size and cavernous interior room (8800 square feet) make it more than big enough for all but the largest events. These upper-end tents are designed to host large-scale events involving many people, and to shelter great numbers of vehicles, exhibition booths, and other equipment. They're available in several different styles from which to choose.
