Tile guide
Tile waste percentage explained
Tile waste is the extra material planned for cuts, breakage, defects, and future repairs. The right percentage depends on the room and layout, so keep it editable.
Area is only the starting point
Calculate the surface area, add the allowance, then divide by the tile area. Round up to a whole tile or package. A diagonal or repeating pattern usually creates more cuts than a straightforward grid.
See where the cuts land
An 8 × 6 ft floor in 12 × 12 in tile is exactly 8 tiles by 6 rows, with no cuts at all. Make the room 8 ft 6 in long and every tile in the last column becomes a cut piece. The tile calculator draws the layout to scale and shades the cut tiles so you can see this before you buy.
Use the label and installation plan
Tile sizes, grout joints, room edges, niches, and installer skill affect the result. Confirm the product’s package count and any pattern-specific recommendation with the supplier or installation guide.
When to plan more
- Diagonal, herringbone, or offset patterns.
- Many corners, niches, or small cut pieces, as on a backsplash.
- Large-format tile where a damaged piece is expensive to replace.
- Future repairs where the same color lot may be unavailable.
