How it works
The area is the length times the width. Each tile covers its length times its width, so the area is divided by one tile's area.
The extra for cuts and breakage is added to the area first. The count is then rounded up to a whole tile.
Worked example
A floor 10 ft by 8 ft, which is 80 ft², with 10% extra for cuts, needs 88 tiles of the size you entered.
Questions
How much extra should be added?
Many people add around 10 percent for a simple square room. Diagonal layouts and many cuts call for more.
Does the grout gap count?
Not in this simple count. Adding the grout gap to the tile size makes the count a little more accurate.
Can spare tiles be kept?
Yes, keep spares for later repairs. Tiles from the same batch match best, so keep a few.
