Enter the area and the tile size, and get the number of tiles, the number of boxes and the adhesive. A wastage allowance covers the tiles you cut at edges and break in handling.

Indicative — type today's local rates. Labour is separate: see the material price lists and labour rates.

Buy a little extra and keep it — dye-lot shades vary between batches, so a few spare tiles from the same lot save a mismatched repair later. Tile adhesive is estimated at ~4 kg/m²; check the bag. Rates on the flooring cost and tiling labour pages.

How it works

  1. Tiles (no waste) = area ÷ the area of one tile.
  2. Add wastage — usually 10% for straight-laid tiles, more for diagonal patterns or small, cut-heavy rooms.
  3. Boxes = tiles ÷ tiles-per-box, rounded up. Tile adhesive is estimated at about 4 kg/m².

Worked example

Tile 100 m² with 600 × 600 mm tiles (0.36 m² each, 4 per box) at 10% wastage:

  • Area with wastage = 100 × 1.10 = 110 m²
  • Tiles = 110 ÷ 0.36 = 306 tiles
  • Boxes = 306 ÷ 4 = 77 boxes

Frequently asked questions

How many tiles do I need for a room? Divide the floor area by the area of one tile, then add about 10% for cuts and breakage. For a 100 m² floor in 600 × 600 tiles that is roughly 306 tiles, or 77 boxes.

How much wastage should I allow for tiles? 10% for a simple straight lay in a regular room; 15% or more for diagonal layouts, small bathrooms, or lots of cuts around fittings.

How much tile adhesive do I need? About 4 kg/m² for a standard notched-trowel bed — check the adhesive bag for its own coverage.

Should I buy extra tiles? Yes, and keep the spares from the same batch. Dye-lot shades vary between production runs, so a later repair from a new box can look mismatched.
