The Arc at Square-brussels Convention Centre

The Arc is 15.3 x 15.3 m (50 x 50 ft), 234 m² (2,520 sq ft), with a 3.5 m (11 ft) ceiling.

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 3.5 m ceiling with 1.5 m trim and 0.3 m clearance you get 3 rows of 500 mm tile flown, which is tight; ground-stack or go lower on trim. Along the 15.3 m wall a Absen A2 Pro wall runs 24 x 3 (4032 x 504 px, 720 kg, 13.3 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, The Arc holds about 333 theater seats, 136 banquet seats at rounds of 10, or 93 classroom seats. Back row in theater is roughly 8.3 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
