Grand EF at St. Louis Union Station Hotel, Curio Collection by Hilton

Grand EF is 27.4 x 27.4 m (90 x 90 ft), 751 m² (8,082 sq ft), with a 6.1 m (20 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 6.1 m ceiling with 1.5 m trim and 0.3 m clearance you get 8 rows of 500 mm tile flown. Along the 27.4 m wall a Absen A2 Pro wall runs 43 x 8 (7224 x 1344 px, 3,440 kg, 63.6 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, Grand EF holds about 1,481 theater seats, 606 banquet seats at rounds of 10, or 416 classroom seats. Back row in theater is roughly 20.4 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
