Add at least 10% for a simple layout and 15% for diagonal patterns or rooms with many cuts. This covers offcuts and breakages.

Multiply its length by its width in metres. A 60×60 cm tile equals 0.6 × 0.6 = 0.36 m².

Spare tiles let you replace damaged pieces later. Production batches differ in shade, so a future top-up may not match.

Yes. Diagonal or offset patterns create more offcuts, so they need a larger margin than a straight grid layout.

For walls you can subtract large openings, but keeping them in adds a useful safety margin for cuts and mistakes.

Tiles are sold by the square metre in full boxes. Round your total up to whole boxes when ordering.
