Estimate the number of tiles, including your chosen allowance for cutting waste.
How do I use this calculator?
Enter values using the stated units. The result updates as you type. To compare two situations, keep the same units and change only the relevant inputs.
The formula
Number = ceiling(area × (1 + allowance/100) / area of one tile).
Quantity estimate without a detailed layout. Joints and patterns may change the requirement.
A practical example
Here is the calculation with the values shown on opening. You can restore them with the reset button.
| Area | 20 m² |
|---|---|
| Tile length | 60 cm |
