How it works

Tiles = ⌈ room area ÷ tile area × (1 + waste%) ⌉

Frequently Asked Questions

How much waste should I add?
A 10% allowance is common for straight layouts, and 15% or more for diagonal patterns or rooms with many cuts.
What units does it use?
Room size is in meters and tile size is in centimeters, a common combination. The result is a whole number of tiles, rounded up.
