Under a 5.5 m ceiling with 1.5 m trim and 0.3 m clearance you get 7 rows of 500 mm tile flown. Along the 39 m wall a Absen PL2.5 Plus V2 wall runs 62 x 7 (12400 x 1400 px, 3,385 kg, 69.4 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 Portage Ballroom holds about 2,933 theater seats, 1,200 banquet seats at rounds of 10, or 825 classroom seats. Back row in theater is roughly 32 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
