Ordering the correct amount of tile ensures consistent dye lots and prevents mid-project delays.

Tile projects always produce cut remnants and breakage. Adding 10% ensures you have enough to finish cleanly.

Boxes = Math.ceil(Total Tiles / Tiles Per Box)

These scenarios demonstrate how key input parameters alter your calculation outcome.

Input: 10ft × 10ft, 12x12 tiles, 10% waste, 10/box

Result: 110 Tiles (11 Boxes)

Why do I need a 10% waste factor for tile?

Tiles must be cut around edges, corners, and plumbing fixtures, creating unusable scraps.
