How it works
Enter floor or wall dimensions (length and width in feet).
Select tile size preset (12x24, 24x24, 3x6 subway, or custom) and grout joint spacing (1/16, 1/8, or 3/16 inch).
Review total tiles needed, square footage to purchase, and estimated grout bag weight.
Frequently asked questions
How much extra tile should I purchase for waste?
Order an extra 10% for straight grid patterns and 15% for diagonal, herringbone, or chevron patterns to account for edge cuts, niche trimming, and accidental breakage.
How does tile size affect grout consumption?
Smaller tiles (like 3x6 subway tiles or mosaics) create far more linear feet of grout lines per square foot, requiring significantly more grout than large-format 12x24 or 24x24 tiles.
