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 7 m ceiling with 1.5 m trim and 0.3 m clearance you get 10 rows of 500 mm tile flown. Along the 114.2 m wall a Absen A2 Pro wall runs 182 x 10 (30576 x 1680 px, 18,200 kg, 336.7 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, Hall 3 holds about 28,794 theater seats, 11,779 banquet seats at rounds of 10, or 8,098 classroom seats. Back row in theater is roughly 107.2 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
