Ballroom I at The Westin Chicago Northwest

Ballroom I is 12.2 x 12.2 m (40 x 40 ft), 149 m² (1,602 sq ft), with a 5.8 m (19 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 5.8 m ceiling with 1.5 m trim and 0.3 m clearance you get 7 rows of 500 mm tile flown. Along the 12.2 m wall a Absen A2 Pro wall runs 19 x 7 (3192 x 1176 px, 1,330 kg, 24.6 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 I holds about 144 theater seats, 58 banquet seats at rounds of 10, or 40 classroom seats. Back row in theater is roughly 5.2 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
