Understanding Tile Waste Factor

Tile waste factor accounts for cuts, breakage, and pattern matching. Standard waste is 10% for simple layouts. For diagonal or complex patterns, use 15%. Large format tiles or rooms with many cuts may need 15-20%. Always buy extra tiles from the same batch to ensure color consistency.
