Tile count with wastage

How to use this calculator

1. Enter surface area (m²). Use the unit shown beside the field.
2. Enter tile length (m). Use the unit shown beside the field.
3. Enter tile width (m). Use the unit shown beside the field.
4. Enter wastage (%). Use the unit shown beside the field.
5. Select Calculate and review the result. Select Reset to restore the example inputs.

How the calculation works

ceil(Surface area (m²)/(Tile length (m)*Tile width (m))*(1+Wastage (%)/100))

Worked example

Surface area (m²) = 20; Tile length (m) = 0.5; Tile width (m) = 0.5; Wastage (%) = 10. Result: 88 tiles.
