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

LED wall that fits

Under a 3.1 m ceiling with 1.5 m trim and 0.3 m clearance you get 2 rows of 500 mm tile flown, which is tight; ground-stack or go lower on trim. Along the 96.4 m wall a Absen PL2.5 Plus V2 wall runs 154 x 2 (30800 x 400 px, 2,402 kg, 49.3 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.
