How it works
How to use the tile calculator
Divide the area to be tiled by the area of one tile, then add wastage for cuts, breakage and future repairs. A 12 × 10 ft room is 120 sq ft; a 600 × 600 mm tile covers about 3.875 sq ft, so you need 31 tiles before wastage and 35 with 10%. Tiles are sold in boxes, so the calculator rounds up to whole boxes using the tiles-per-box figure printed on the box.
Allow more wastage (12–15%) for diagonal laying, many corners, large-format slabs or patterned tiles that must match, and less for simple square rooms. Leave out areas under fixed kitchen cabinets or wardrobes if they won't be tiled.
For walls, enter the wall width and height as length and width, and subtract doors and windows. Buy all boxes from the same batch (shade and calibre code), because colour can differ slightly between batches.
- Enter the room or wall size.
- Choose the tile size and tiles per box.
- Set wastage (10% is typical).
- Read the number of tiles and boxes.
