How this is calculated
We divide your total area by the square footage of a single tile, then add a waste allowance for cuts and breakage. Straight layouts need less waste (10%); diagonal and herringbone patterns need more (15–20%) because more tiles are cut at an angle.
Buying tip
Box coverage varies by manufacturer — always check the actual sq ft per box printed on the product, and round up to the nearest full box. Buying 1 extra box beyond this estimate is common practice in case of future repairs, since dye lots change over time.
Grout estimate is approximate and varies by joint width and tile thickness — check your grout manufacturer's coverage chart.
