Plan view

LED wall that fits

Under a 5.2 m ceiling with 1.5 m trim and 0.3 m clearance you get 6 rows of 500 mm tile flown. Along the 18.9 m wall a Absen A2 Pro wall runs 30 x 6 (5040 x 1008 px, 1,800 kg, 33.3 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.

Seating estimate

After a 12 x 7 m stage, A3 holds about 384 theater seats, 157 banquet seats at rounds of 10, or 108 classroom seats. Back row in theater is roughly 11.9 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
