Beginning your Arena Design - Basic seating Layout terms


An arena reflects the spirit and strength of a college or city. It can anchor your community and provide a year-round revenue stream from sports, concerts and special events. An arena is meant to be busy, so it should be a nimble facility, with the ability to easily adjust its footprint to accommodate a variety of events.

Secondary experiences have become a critical part of attracting patrons to an arena. WiFi connectivity, lounges and seating options that range from general admission to luxury suites are common. But the primary experience is on the court/stage. To foster that great energy, sound and sense of community a successful event brings, seating will be one of your first challenges.  

The types of events you will host, population of your community within driving distance, and historical attendance of sporting events should all be considered when planning your seating capacity. While you work on those numbers, we’ll share some commonly used seating layout terms.
