FAQ
Frequently asked questions
Why add a wastage allowance?
To account for cutting, breakage, and pattern matching, which typically waste some tiles.
What wastage percentage should I use?
10% is common for straight layouts; diagonal or complex patterns often need 15% or more.
Is the result rounded up?
Yes, always rounded up to the next whole tile, since you can't buy a fraction of a tile.
How do I find my tile's area?
Multiply the tile's length by its width, in the same units as your floor area.
