Frequently asked questions
What formula does this calculator use?
Area to tile = length × width; Tiles needed = ceil(length × width ÷ tilearea × (1+waste ÷ 100)). Variables: length = length in m, width = width in m, waste = waste allowance in %. Fixed values: tilearea = 0.18.
What do I need to enter?
You need length (m), width (m), waste allowance (%). Results update as you type.
What is an example result?

One tile covers 0.18 m², before allowing for grout lines. Check the pack size, since tiles are usually sold by the box.
