Tile Quantity Calculator lets you tile count rounds up surface area divided by tile area plus waste allowance. Enter your own values or load the worked example.

Method and calculation

Tile count rounds up surface area divided by tile area plus waste allowance.

Inputs and settings

Tile Quantity Calculator accepts Surface area (m²) (minimum 0.000001); Tile width (cm) (minimum 0.000001); Tile height (cm) (minimum 0.000001); Waste (%) (minimum 0, maximum 100).

Worked example

Tile Quantity Calculator example — Surface area (m²): 20; Tile width (cm): 60; Tile height (cm): 60; Waste (%): 10. Computed output: { "tiles": 62 }
