Tile calculator.
Estimate floor or wall tiles from area, tile size, border allowance and wastage.
Tile inputs
Grout-joint width is retained for layout checking; grout quantity is not estimated. Confirm pattern, cuts and spare-tile policy with the installer.
Method: Increase net area by border/cut allowance and wastage, then divide by one tile face area. Grout-joint width remains a visible layout input.
Inputs used: Surface area = 120 sq ft; Tile width = 600 mm; Tile height = 600 mm; Border and cut allowance = 0 %; Wastage buffer = 10 %; Grout joint width = 3 mm
Assumptions: Site and equipment inputs are planning assumptions supplied by the user or displayed by the calculator.
Scope and warnings: Grout-joint width is retained for layout checking; grout quantity is not estimated. Confirm pattern, cuts and spare-tile policy with the installer. Obtain site-specific engineering and equipment checks before purchase or installation.
How this tile calculator works
Increase net area by border/cut allowance and wastage, then divide by one tile face area. Grout-joint width remains a visible layout input.
A worked example
A 120 sq ft surface using 600 × 600 mm tiles and 10% wastage needs 38 tiles before a site layout check.
Why can final count differ?
Pattern, diagonal cuts, room shape, batch matching and spare-tile policy affect the order.
Calculations run on your device. Review your results before exporting or sharing them.
Measure the finished surface
Use floor or wall area after deciding whether skirting, niches and reveals are included. Tile dimensions are face dimensions; the joint is a layout input, not grout material quantity.
Order allowance depends on cuts and pattern. Check a scaled layout and keep matching spare tiles when future repair matters.
