Plan view

Shape approximate: the venue publishes area only, so this room is drawn as a square of equal area.

LED wall that fits

Under a 16 m ceiling with 1.5 m trim and 0.3 m clearance you get 28 rows of 500 mm tile flown. Along the 244.9 m wall a Absen A2 Pro wall runs 391 x 28 (65688 x 4704 px, 109,480 kg, 2025.4 kW).

Wall sizing assumes 1.5 m trim to the bottom edge, 0.3 m clearance under the ceiling, and a wall no wider than 80% of the longest wall. Weight and power are tile totals from the panel spec sheet; add processing, rigging, and cable.

Seating estimate

After a 12 x 7 m stage, Challenger Hall 1-3 holds about 133,093 theater seats, 54,447 banquet seats at rounds of 10, or 37,432 classroom seats. Back row in theater is roughly 237.9 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
