The HomeCraft Tile & Flooring Estimator gives you exact tile counts including waste factor, grout spacing, and pattern adjustments.
Calculating the right number of floor tiles or wall tiles is crucial before starting any tiling project. Order too few and you risk mismatched tiles from a different production batch; order too many and you've wasted money. Our tile calculator solves this by factoring in your room's exact area, your chosen tile size, grout line spacing, the tile pattern, and an adjustable waste percentage — all in one place.
The tile waste factor accounts for tiles that are cut, broken, or discarded during installation. For a straight grid pattern, a 10% waste factor is typically sufficient. However, diagonal or herringbone patterns require significantly more cuts, meaning more wasted tile. We recommend 10–15% for diagonal patterns and up to 20% for complex herringbone layouts. Our calculator lets you select the pattern type and automatically suggests an appropriate waste multiplier while still letting you fine-tune the percentage.
Never forget to include grout spacing in your calculations. Even a 1/4-inch grout line adds up significantly when multiplied across hundreds of tiles. Our tile estimator adds your specified grout gap to each tile's effective dimensions before calculating coverage, giving you a far more accurate result than tools that ignore grout spacing entirely.
