Tiles needed are room area ÷ one tile's area, plus wastage, rounded up: 10 m² of 30 × 30 cm tiles (0.09 m² each) with 10% waste is ceil(10 ÷ 0.09 × 1.1) = 123 tiles. Length and width go in centimetres while area stays in square metres — the page converts between them, so never pre-convert by hand.
Measure the floor or wall, enter the tile's centimetre dimensions, and set waste to the layout: 10% for straight runs, 15–20% for diagonal or patterned work with many cuts. Order everything — including a few spares for future repairs — from the same batch, because dye lots differ between production runs.
It does not estimate adhesive or grout, deduct fixtures, or lay out the pattern — count tiles here, then price mortar and grout from their own coverage figures.
Tiles only — adhesive and grout need their own figures.
Around 10% for a straight layout, and 15–20% for diagonal or heavily patterned work with many cuts.
No — it counts tiles only. Estimate adhesive and grout from their own coverage figures.
Later production runs can differ slightly in shade and size. A few spare boxes from the original batch keep future repairs invisible.
