How much extra tile should I order?

Order 10% extra for standard installations and 15% extra for diagonal or complex patterns. Always buy extra from the same dye lot to ensure color consistency for future repairs.

How do I account for grout joints?

Standard grout joints are 1/8 inch for floor tiles and 1/16 inch for wall tiles. The calculator adds the grout joint to each tile's dimensions before computing the total count.

What is a 'dye lot' and why does it matter?

Tiles from the same production batch share a dye lot number and have consistent color. Different lots can have subtle variations, so order all needed tiles from the same lot.
