Main Hall at Hiroshima Convention Hall & Hybrid Studio

Main Hall is 26.9 x 26.9 m (88 x 88 ft), 724 m² (7,789 sq ft), with a 5 m (16 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 5 m ceiling with 1.5 m trim and 0.3 m clearance you get 6 rows of 500 mm tile flown. Along the 26.9 m wall a Absen A2 Pro wall runs 43 x 6 (7224 x 1008 px, 2,580 kg, 47.7 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, Main Hall holds about 1,421 theater seats, 581 banquet seats at rounds of 10, or 399 classroom seats. Back row in theater is roughly 19.9 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
