Calculate tile square footage, waste allowance and the number of tiles needed from floor or wall dimensions and tile size.
The calculator turns your project area and tile dimensions into an individual tile count. Waste covers cuts, breakage and a small reserve for future repairs.
Tiles = area with waste \u00f7 individual tile areaA 10 \u00d7 10 ft floor is 100 sq ft. With 10% waste and 12 \u00d7 12 in tiles, plan for about 110 tiles.
About 10% is common for a simple straight layout. Complex patterns, lots of cuts or fragile tile may justify 15% or more.
Usually the effect is small for room-scale estimates. For very large tiles or wide joints, a detailed layout can refine the count.
Yes. You cannot buy part of a tile, and keeping a few spares is useful for future damage.
Measure each tiled wall separately, subtract any large untiled openings if appropriate, then total the areas and apply a waste allowance.
