Tent Dimensions: 20 X 40. We do need to have an additional 7-10 feet on each side of the canopy for set up. Based on our experience 14- 6ft tables and 84 chairs would comfortably fit in this canopy. For round tables, 10 round tables and 80 chairs would comfortably fit in this canopy. Additional Information: The base price for a 20’ x 40′ tent on grass is $550. If setting up on concrete, water barrels will be required at an additional cost. Depending on situation and area, there may be additional fees for permits. Set up/tear down and delivery fees vary. Please submit your cart order and we will reply with the total fees. If you would like sidewalls, let us know on the message option within your order. If walls are needed, please specify solid or cathedral windows. All orders that contain one or more canopy(s) 20x20 or larger will also include a delivery fee regardless of the area. Please contact the office to calculate a delivery rate.
