How the tile calculator works
Floor area is straightforward: length × width. Tile size is given in inches (or cm in metric mode), so each tile covers tile_w × tile_h in the appropriate units. Divide the total area by area-per-tile, apply the waste factor, and round up to whole tiles.
Choosing the right grout
- Unsanded grout — joints less than ⅛" / 3 mm. Smooth finish, works for polished stone or tight wall tile.
- Sanded grout — joints ⅛" to ⅜" / 3–10 mm. The sand gives it structural strength.
- Epoxy grout — wet areas, commercial floors, or anywhere you need maximum stain resistance. Harder to install, more expensive, but permanent.
Common questions
Why do I need a waste factor for tile?
Every edge that doesn't land on a full tile gets cut. Cuts produce offcuts that are usually too small to reuse. Add the inevitable broken tile from handling. 10% is the floor; complex layouts demand more.
What's the easiest pattern for DIY?
Straight layout (grid) with a large-format tile (18×18 / 45×45 or larger) for floors, or subway tile for walls. Fewer cuts, fewer visible errors.
