What fits in Skyline Ballroom at McCormick Place W375

With a 12.2 m ceiling, a flown wall of Absen A2 Pro (2.97 mm) runs 234 tiles wide by 20 high (4680 tiles, 117 x 10 m, 39312 x 3360 px) once you keep 1.5 m of trim under the bottom edge. That wall weighs about 46,800 kg and draws up to 865.8 kW (4163 A at 208 V). Floor space after a 12 x 7 m stage seats roughly 20,565 theater, 8,413 banquet, or 5,783 classroom. The previz lets you move the wall, change the tile, and check sightlines from the back row.

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.

Planning notes

No rigging point data is published for this venue yet; plan on ground-supported LED or ask the venue for its rigging plot. 57 of the 101 rooms sit under 3.5 m, which rules out flown LED there and limits ground-stacked walls to about 6 rows of 500 mm tile.
