How to use tile calculator

  1. Set Coverage (m²). The example below uses 20.
  2. Set Tile length (cm). The example below uses 30.
  3. Set Tile width (cm). The example below uses 30.
  4. Set Waste (%). The example below uses 10.
  5. Select Calculate to update the result. Reset restores the illustrated inputs. Copy, print or download your own result if you need a record.

Factors affecting your result

Excludes grout joints, package rounding and complex patterns.

Changing coverage (m²) changes the scenario being evaluated. Adjust one input at a time when comparing results, keep a copy of the assumptions, and compare values using the same unit and period. A precise arithmetic result does not make an uncertain assumption precise.

Frequently asked questions

How does the tile calculator work?

Tiles = ceil[area × (1 + waste) / tile area].

What inputs does Tile Calculator need?

Enter coverage (m²), tile length (cm), tile width (cm), waste (%). Read the unit labels; percentages are entered as ordinary percentages, not decimal fractions.

How should I interpret the tile calculator result?

Excludes grout joints, package rounding and complex patterns.

Are my tile calculator inputs uploaded?

No. The calculation runs in this browser. Favorites, recent tool names, theme and formatting preferences may be saved locally, but calculation inputs are not sent to a calculation server or stored by this website. Shared links do not include entered values.
