Check it outFrom tiles to boxes to budget
Tile is sold by the box, so the useful number is how many boxes to buy. Enter tiles per box (on the carton) and price per box to turn the raw tile count into an order and a cost. Add 10% waste for straight layouts and 15–20% for diagonal patterns, and keep a few spares from the same lot for repairs.
How it’s calculated
Tiles = area ÷ tile area × (1 + waste). Boxes = tiles ÷ tiles per box, rounded up.
