Tile Coverage & Carton Boxing Formulas
Surface area is divided by individual tile square footage, factored by pattern complexity waste, and grouped into retail cartons:
Tiles = ⌈(Area ÷ Single Tile Sq Ft) × (1 + Pattern Waste%)⌉ | Boxes = ⌈Tiles Needed ÷ Tiles Per Box⌉Step-by-Step Step Rule:
- 1Enter floor or wall dimensions (or direct net square footage).
- 2Select your tile format (Subway 3x6, Standard 12x12, Modern 12x24, or Large Format 24x24).
- 3Choose your layout pattern (Straight Grid 10%, Offset Brick 10%, Diagonal 15%, Herringbone 15%).
- 4Enter your specific tile manufacturer’s pieces-per-box to determine cartons to buy.
