Carpet Tile Calculator
Carpet tiles are laid square by square, so the count depends on the tile size. This works out how many tiles a room needs, with an allowance for cuts at the walls.

How it works
Floor area is length times width. Add an allowance for cuts, often about 10 percent, then divide by the area of one tile, which is its side times its side. Round up to a whole tile.
Some patterns change how many cuts are needed, such as a turned or brick layout. Add a little more allowance for those.
Worked example
A room 16 ft by 12 ft, which is 192 ft² of floor, needs 53 tiles, with cuts allowed for.
Questions
What tile size is common?
Many carpet tiles are about 50 centimetres, or 24 inches, square. Check the size on the box before you count.
Do I need spare tiles?
Many people keep a few spare tiles from the same dye lot, since colour can differ between batches.
Does the pattern change the count?
It can. Patterns that run in a different direction need more cuts, so give them a larger allowance.
