Your exhibit will take up roughly thirty square feet in a ten-foot-by-ten-foot booth (100 square feet). Only 75 square feet are available for exhibitors and guests. There are approximately 4,000 square feet of floor space in an average-size convention center. A larger venue may have more than one level with room on another side or back for additional display space. Exhibits at large conventions tend to be smaller because there's less opportunity for vendors to compete by offering different products. Also, the cost of renting a booth at a large show can be prohibitively expensive. At small shows, vendors can afford to offer more extravagant displays that would not be possible at larger events. These shows are good opportunities for start-ups who want to get their name out there without spending a lot of money. Large conventions also offer discounted rates to exhibitors. The more traffic your booth receives, the more likely you are to receive a discount. At small shows, everyone tries to attract attention by putting on a showy display or using music blasts. This causes prices to go up for everyone at these events. The best way to decide how much space you need is by thinking about what you intend to do with your display and then calculating accordingly.
