Working Out Tiles Needed

Tiles per m² = 10,000 ÷ (tile width cm × tile height cm). A 30×60cm tile = 5.6 tiles/m². Multiply by your area, add 10% for cuts and breakages — more (15%) for diagonal patterns or rooms with many obstacles.

Adhesive and Grout

Wall tiling with a thin adhesive bed uses roughly 3.5kg/m²; floor tiling with a thicker bed uses 4–6kg/m². Grout usage rises with smaller tiles (more joints) and wider joints — mosaic tiles can need triple the grout of large-format tiles.

Setting Out Matters Most

Professional-looking tiling comes from planning: centre the pattern on the focal wall, avoid slivers of cut tile at edges, and check the first row is perfectly level — every subsequent row follows it.

Frequently Asked Questions

How many tiles do I need per square metre?

Divide 10,000 by the tile area in cm². A 30×60cm tile gives 5.6 tiles per m²; a 10×10cm mosaic gives 100 per m².

How much extra should I buy for cuts?

Add 10% for straight layouts and 15% for diagonal patterns or rooms with lots of obstacles. Keep spares for future repairs.

How much tile adhesive per m²?

Around 3.5kg/m² for walls with a thin bed, 4–6kg/m² for floors with a thicker notched bed.
