Flooring & Tiling calculator
Floor Tile Calculator
Calculate floor-tile count and box quantity from floor area, tile size and a cutting allowance suited to the floor layout.
Calculate floor-tile count and box quantity from floor area, tile size and a cutting allowance suited to the floor layout. Enter the project measurements first, then replace any default material or performance value with data for the product you intend to use. Check tile layout and cutting waste carefully. The calculator treats tile face area geometrically; borders, niches, diagonal layouts and pattern matching can increase the real number of tiles needed.
What you need to enter
The Floor Tile Calculator uses the following project information to calculate the result.
- Surface area
- Tile length
- Tile width
- Waste (%)
- Tiles per box

Tiles and optional boxes required
How the Floor Tile Calculator works
Calculation logic: surface area with waste ÷ tile face area. For floor tiles and boxes for a measured floor, the Floor Tile Calculator uses that method after normalising the entered units. The output is then converted for display. The practical assumption that deserves the closest check is tile layout and cutting waste.
Floor Tile Calculator worked example
Floor Tile Calculator example: For 12 m² of floor tiling using 600 × 300 mm tiles, each tile covers 0.18 m². After a 10% waste allowance, the theoretical count is about 74 tiles; if a box contains 8, the order rounds up to 10 boxes. After calculating, compare the result with the job conditions and especially tile layout and cutting waste before rounding or selecting materials.
Important calculation assumptions
For floor tiles, tile face area is only the starting point. Thresholds, room edges, diagonal cuts and breakage affect waste, while substrate flatness and movement-joint requirements are separate installation checks.
Frequently asked questions
What do I need to enter before the Floor Tile Calculator can give a useful result?
Measure the tiled surface, enter the actual tile dimensions and box quantity, then choose waste for cuts and the intended layout. Those entries form the basis for estimating floor tiles and boxes for a measured floor.
How can errors in tile layout and cutting waste change the Floor Tile Calculator result?
Before relying on the Floor Tile Calculator, check tile layout and cutting waste. The calculator treats tile face area geometrically; borders, niches, diagonal layouts and pattern matching can increase the real number of tiles needed.
How should I turn the Floor Tile Calculator result into an order quantity?
Once the Floor Tile Calculator has produced a result, round up to whole tiles and then whole boxes where a box count is entered. Keep spare matching tiles for breakage and later repairs, particularly with batch-sensitive finishes.
