This is dependent on the number of people that will be under the tent at any given time and what they will be doing. Banquet Seating (people sitting at tables) and Auditorium Seating (people sitting in chairs, in rows like in a theater) are listed next to the sizes of tents. Adding a dance floor, DJ/Band, buffet tables, gift tables, etc. will most likely require the next size (or possibly two sizes) up. Use the Space Planner on our website to help you determine the size of tent you will need.
