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 20.6 m wall a Absen PL2.5 Plus V2 wall runs 32 x 2 (6400 x 400 px, 499 kg, 10.2 kW).

| Absen KLCOB 0.78 | 0.78 mm | 27 x 3 = 81 | 16.2 x 1 m | 20736 x 1296 | 365 kg / 804 lb | 7.2 kW, 34 A @ 208 V |
| Absen PL2.5 Plus V2 | 2.5 mm | 32 x 2 = 64 | 16 x 1 m | 6400 x 400 | 499 kg / 1,101 lb | 10.2 kW, 49 A @ 208 V |

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, Columbia Ballroom Prefunction holds about 756 theater seats, 309 banquet seats at rounds of 10, or 212 classroom seats. Back row in theater is roughly 13.6 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
