About this calculator
Full grid takeoff for a suspended ceiling: tiles, main runners, long and short cross tees, perimeter angle and hanger wires.
How it’s calculated
Main runners run across the width at 4 ft centres. Long cross tees span between mains every 2 ft. For square tiles, short tees split each bay. Wall angle runs around the perimeter.
Worked example
With these inputs:
- Room length
- 20 ft
- Room width
- 16 ft
- Tile size
- 2 × 2 ft
- Waste allowance
- 5%
the result is:
- Ceiling tiles
- 84 tiles
- Main runner rows
- 3
- Area
- 320 sq ft
Tips from the trade
- Centre the grid so the border tiles at opposite walls match and are more than half a tile wide.
- Hang a wire every 4 ft along each main, and within 6" of each splice.
