Frequently asked questions
How do I find sq ft per tile box?
Multiply tile length × width in inches, divide by 144 for sq ft per tile, then multiply by pieces per box. Or use the coverage printed on the box.
Does this work for wall tile?
The math is the same — enter wall length and height as your room dimensions. Consider extra waste for outlets and niches.
