Frequently Asked Questions

3 questions
Q1 How much waste should I add for tile?
Standard rooms: add 10% for waste. Diagonal layouts or complex rooms: add 15–20%. Always round up to the nearest box.
Q2 How do I calculate tile for a floor?
Multiply the length by the width of the room to get total square footage, then divide by the tile area in square feet. Add your waste percentage.
Q3 What size tile is easiest to install?
12×12 inch tiles are the most common for DIY. Large format tiles (24×24 in) look great but require a flatter surface and more skill to install.
