How it's calculated

Tiles = area × (1 + waste %) ÷ tile area, rounded up
Boxes = tiles ÷ tiles per box, rounded up

Counts the tiles to cover a rectangular floor or wall, plus a waste allowance for cuts and breakage, and the boxes that makes. Use 10% for a straight layout and 15% or more for diagonal or herringbone. Keep a few spare tiles for later repairs.
