Question 1

Why do I need a waste factor for flooring?

Accepted Answer

When installing flooring (laminate, tile, or carpet), you must cut pieces to fit corners and edges. These scraps are usually unusable. A 10% waste factor ensures you have enough material to complete the job without running out.

Question 2

Is 10% waste enough for tile?

Accepted Answer

For simple layouts, 10% is standard. However, if you are laying tile in a diagonal pattern or have many intricate cuts around plumbing, you should increase the waste factor to 15-20%.

Question 3

How do I calculate for multiple rooms?

Accepted Answer

It's best to calculate each room individually and sum the results, as each room has its own edge-to-area ratio. This tool helps you get the exact requirement for a specific space or unit turn.
