Each ring has a diameter of 30 cm (1 foot) and up to 5 tubes can be provided for the spring line desired by the customer. One or two tubes hold the dome diameter and adds to stability. Three to five tubes provide a wall against which chairs can be placed. Customers wanting a dome structure with chairs often choose the ring dome.All 4 and 5 meter domes come with the standard 6 foot door. All others come with the new 7 foot door unless otherwise specified.Following are the reference size for clients to choose:
  SEATING CAPACITY FOR RAISED DOMES (non-raised dome capacities are smaller, due to the projection surface reaching the floor and audience members obstructing each others view) Grey squares represent small folding chairs.Ground seating will allow for greater capacity (depending on the age of the group). LEFT: unidirectional configuration with a spherical mirror (ideal for both full dome films and night sky) RIGHT: concentric configuration with a fish eye projector (ideal only for night sky)  The illustrations above represent round and theater seating for 4 to 9 meter Domes. The gray squares are the size of standard folding chairs that can be reasonably placed for safe operations. Of course if ground seating is preferred, the the capacity will change depending on the age of the group.. Generally speaking floor seating will allow for more people to be seated than chairs. A simple way of calculating capacity for yourself is to draw a circle the diameter of the dome you intend to buy and sit some representative people inside your circle and do a head count.
