How this calculator works
Enter the values for first value, second value and review the units before calculating.
Formula / method
Tiles = area ÷ tile area × (1 + waste ÷ 100)
Worked example
24 m² using 0.6 m × 0.6 m tiles at 10% waste requires 74 tiles after rounding up.
Assumptions and limitations
Tiles are rectangular and the waste percentage covers cuts and breakage.
Pattern direction, grout joints, room geometry and spare stock can change the required order.
