Formula & explanation
Tiles = ceil[room area/(tile length×tile width) × (1+waste/100)]
Variables & units
- Length
- m · minimum 0, maximum 1000000000000
- Width
- m · minimum 0, maximum 1000000000000
- Tile length
- m · minimum 0.000001, maximum 1000000000000
- Tile width
- m · minimum 0.000001, maximum 1000000000000
- Waste allowance
- % · minimum 0, maximum 100
Worked example
5 m × 4 m with 0.6 m × 0.6 m tiles and 10% waste needs 62 tiles.
