FAQ
Common questions
How much tile waste should I add?
It varies by layout and pattern. A diagonal or complex pattern often creates more cuts than a simple straight layout.
Should I buy extra tile for future repairs?
Many people keep extra matching material because dye lots and product lines can change.
Does grout-joint width change tile count?
Slightly, but this planning calculator does not use grout-joint width.
