Tile Calculator
Find out exactly how many tiles you need: floor area, tile size and waste percentage, with boxes to buy.
About this tool
This tile calculator converts room area and tile dimensions into the exact number of tiles to order, including your chosen waste percentage.
Under-ordering is the single most common tiling mistake: patterns get broken mid-wall and the replacement batch rarely matches color. Over-order by the waste factor, keep the rest for repairs, and the job never stalls.
FAQ
How much tile waste should I add?
10% is standard for straight layouts; 15% for diagonal or large-format tiles where cuts are more frequent.
How do I calculate the area?
Length x width in meters for floors; width x height for walls, minus doors and windows (or keep them for safety).
What are sensible tile sizes?
60x60 for large rooms, 30x60 for bathrooms, 10x10 for feature walls — each affects waste and grout lines.
