Tile Calculator
How many tiles for a floor, wall, or backsplash — with the waste factor that matches your layout, the boxes to buy, and a cost estimate.
Tile is priced and wasted differently from sheet or plank flooring, which is why it needs its own calculator. Enter the area, the size of a single tile, and your layout pattern; the tool returns the tiles to buy (waste included), the box count, and a cost range for material and labor.
For floors specifically, cross-check with the Flooring Estimator, and fold the total into your Renovation Budget. The full cost breakdown is in the flooring installation cost guide.
FAQ
- How much extra tile should I order?
- 10% over the area for a straight layout, ~15% for diagonal, ~20% for herringbone — the more cuts a pattern needs at the edges, the more waste. This calculator builds the right waste factor in based on the pattern you choose.
- How is a tile calculator different from a flooring estimator?
- Flooring is sold by the box covering a known square footage and only goes on floors. Tile is sized per piece in inches, can go on walls and backsplashes too, and its waste swings with the layout pattern — so the math is different.
- Why buy from the same dye lot?
- Tile color varies slightly between production batches (dye lots). Order all your tile — including the waste overage — at once from one lot, and keep the spares. A matching replacement years later is nearly impossible.
