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.

After a 12 x 7 m stage, S403 holds about 742 theater seats, 303 banquet seats at rounds of 10, or 208 classroom seats. Back row in theater is roughly 13.9 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
