Flooring & Tiles calculators
Tiles, grout, laminate and carpet — in boxes you can buy.
Before you buy
Tiles and laminate are sold by the box, and every box covers a fixed area. Our flooring calculators work out the floor area, add an allowance for cuts and breakages, and round up to whole tiles and whole boxes, so you don't end up one box short halfway through the job.
The coverage per box and the number of tiles per box are printed on the packaging. Enter them for an exact count.
Quick tips
- Keep about 10% extra for straight layouts. Diagonal and herringbone patterns need more because of extra cuts.
- Buy all boxes from the same batch so the colour and size match.
- Keep one spare box for future repairs.
- Measure each room separately and add them together. Don't guess a whole floor at once.
