Includes wastage. Round-ups are built in. A single large order from one batch also keeps tile shades consistent.
How this works
Tiles = area × (1 + wastage) ÷ area of one tile, rounded up. Boxes = tiles ÷ tiles per box, rounded up. Adhesive bags = area × adhesive use per m² ÷ bag weight, rounded up. Adhesive use depends on tile size, trowel and surface, so the figure here is a typical starting point. Check your adhesive's data sheet.

Common questions
About this tool
How much extra tile should I order?
Most jobs add 5 to 10 per cent for cuts and breakage. Use 10 to 15 per cent for diagonal layouts, patterned tiles or small rooms with many cuts.
How much tile adhesive do I need per square metre?
It varies with tile size and trowel notch. As a rough guide, small tiles use around 3 to 4 kg per m², large-format tiles use more, because they need a thicker bed and often back-buttering.
Which tile adhesive is right for large vitrified tiles?
Use a polymer-modified adhesive rated for large-format and low-porosity tiles. Tell us your tile size and substrate and we will suggest the right grade.
