Frequently Asked Questions (FAQ)
Why does grout width affect tile count?
Grout joint gap adds to the effective size of each tile. For small tiles, a thick grout line can reduce the total tile piece count by 5-10%.
What is the recommended tile waste percentage?
Use 10% for straight grid layouts and 15% for diagonal or complex patterns like herringbone where more cuts are needed.
