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, Chelsea holds about 248 theater seats, 101 banquet seats at rounds of 10, or 70 classroom seats. Back row in theater is roughly 21 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
