Under a 2.7 m ceiling with 1.5 m trim and 0.3 m clearance you get 1 rows of 500 mm tile flown, which is tight; ground-stack or go lower on trim. Along the 85.3 m wall a Absen A2 Pro wall runs 136 x 1 (22848 x 168 px, 1,360 kg, 25.2 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.
