Ballroom L'Espace is 21.2 x 21.2 m (70 x 70 ft), 449 m² (4,837 sq ft), with a 3.1 m (10 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 3.1 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 21.2 m wall a Absen PL2.5 Plus V2 wall runs 33 x 2 (6600 x 400 px, 515 kg, 10.6 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, Ballroom L'Espace holds about 811 theater seats, 332 banquet seats at rounds of 10, or 228 classroom seats. Back row in theater is roughly 14.2 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
