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, Walnut Gallery holds about 53 theater seats, 22 banquet seats at rounds of 10, or 15 classroom seats. Back row in theater is roughly 6.7 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
