Garage Floor Tile Calculator
Enter garage width, depth, tile size and wastage. The calculator returns tile count, floor area and the number of boxes to order.

Coverage-with-wastage: 39.60 m². Always cross-check tile count against a scaled floor plan before ordering — cut tiles at the perimeter and the roller-door threshold can shift the count by one box.
How the calculation works
Floor area is width × depth. The calculator applies your wastage percentage first, then divides by the per-tile face area to get the tile count and by the per-box coverage to get boxes needed. Both figures round up to the next whole tile or box so the perimeter cuts and the roller-door threshold row are covered.
Box coverage varies by supplier — a 450 mm ceramic box with 10 tiles is roughly 2.02 m², but always confirm against the label before ordering. A single box in either direction can shift the count on a small garage.
Ordering grout and adhesive as well? Use the tile and grout estimator — same tile size, floor area and wastage inputs, plus outputs for adhesive bags and grout kilograms. Quoting a whole-house fitout with a garage tile section? Mark each room from a PDF plan in AreaSum and the report rolls totals up per material. See how it works.
