Tile Calculator
Work out exactly how many tiles you need for any room. Enter the area you're covering, choose your tile size, and we'll add the recommended 10% for cuts and breakages.
How to work out how many tiles you need
Four steps and a calculator — no guesswork.
Measure the area
Measure the width and length of each wall or floor in metres, then multiply the two for the area of each surface.
Add the areas together
Add up every surface you're tiling to get your total square metres. For odd shapes, break the space into rectangles and add them.
Add 10% for wastage
Always order around 10% extra to cover off-cuts and the occasional breakage — closer to 15% for diagonal layouts or busy patterns.
Convert to tiles & round up to full boxes
Divide your total by the area one tile covers, then round up to whole boxes. The calculator above does all of this for you.

It depends on the tile size. Divide 1 by the area one tile covers in square metres. A 60 × 120 cm tile covers 0.72 m², so you need about 1.4 tiles per m². A 60 × 60 cm tile covers 0.36 m², so roughly 2.8 per m².
Around 10% is the standard allowance for straight layouts, covering off-cuts and breakages. For diagonal patterns, herringbone or rooms with lots of corners and pipes, allow closer to 15%.
Split the space into simple rectangles, work out the area of each one (width × length), then add them together. It's fine to tile over small fixed features — measuring the full rectangle just gives you a little extra coverage.
Tiles are supplied in sealed boxes, so orders are rounded up to the next full box. The leftover tiles double up as your wastage allowance and a few spares for future repairs.
Yes — hold back a few tiles from your order. If one ever chips or cracks you can swap it without trying to match a dye lot, which can shift slightly between production batches.
