Layout Tips
Center the grid so border tiles on opposite walls are equal. Avoid border tiles narrower than half a tile width for a balanced appearance.
Example Calculation
A 20 x 16 foot room using 2 ft x 2 ft ceiling tiles.
- 01Ceiling area = 20 x 16 = 320 sq ft
- 02Main runners = ceil(20/12) x ceil(16/4) = 2 x 4 = 8 pieces (12 ft each)
- 034-ft cross tees = ceil(20/4) x (4+1) = 5 x 5 = 25 pieces
- 042-ft cross tees = ceil(20/2) x 4 = 10 x 4 = 40 pieces
- 05Wall angle = ceil(72/12) = 6 pieces (12 ft each)
- 06Tiles = 10 x 8 = 80 tiles (2x2)
