To find the number of tiles needed: divide the total area by the area of one tile (including grout joint), then add a waste factor for cuts and breakage.
Waste Factors by Pattern
Straight lay: 10% — minimal cuts, most efficient
Offset / brick pattern: 12–15% — more cuts at edges
Diagonal 45°: 15–20% — all perimeter tiles are cut at 45°
Complex pattern / herringbone: 20–25% — maximum waste
Grout & Thinset Estimates
Grout coverage varies by joint width and tile size. A standard 50 lb bag of thinset covers approximately 40–60 sq ft depending on tile size and notch trowel used.
