Tile and grout estimator
Enter floor area, tile size, joint width and wastage. The calculator returns the tile count, adhesive bags and grout kilograms.
Inputs
Result
Adhesive assumes 4 kg/m² with a 6 mm notched trowel. Grout is calculated from tile size, joint width and thickness at a typical cementitious density (1.6 g/cm³). Confirm against the spec on your supplier's technical data sheet.
How the calculation works
Tile count is the area (with wastage applied) divided by the tile face area, rounded up to a whole tile. Adhesive assumes 4 kg/m² coverage at a 6 mm notched trowel; we round up to the next 20 kg bag. Grout kilograms are calculated from the joint volume per square metre — ((tile length + tile width) × joint width × tile thickness) divided by (tile length × tile width), multiplied by a density factor of 1.6 (typical cementitious grout).
For multi-room jobs (bathrooms, ensuites and living areas in the same project), mark each room from a PDF plan in AreaSum and the report rolls totals up per material so adhesive and grout figures stay accurate. See how it works.
