Summit - Room 321 at Seattle Convention Center

Summit - Room 321 is 11.6 x 11.6 m (38 x 38 ft), 135 m² (1,449 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 11.6 m wall a Absen A2 Pro wall runs 18 x 2 (3024 x 336 px, 360 kg, 6.7 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, Summit - Room 321 holds about 112 theater seats, 45 banquet seats at rounds of 10, or 31 classroom seats. Back row in theater is roughly 4.6 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
