How the Estimate Works
The tile count is calculated using the floor area and tile size with a layout-specific waste factor:
Waste factors vary by layout: 10% for straight grid, 15% for diagonal, and 20% for herringbone patterns. Always buy extra tiles and store them for future repairs — matching tile color and dye lot is nearly impossible once a batch is discontinued.

How many 12×12 tiles do I need for a 10×12 room?
For a 10×12 room (120.00 sq ft) using 12×12 inch tiles in a straight grid pattern, you need 120 tiles before waste and 132 tiles including the 10% waste factor for cuts. Each tile covers 1.00 sq ft. Use our interactive Tile Calculator to adjust tile sizes, layout patterns, and waste factors.
How much extra tile should I buy for a straight grid pattern?
For a 10×12 room with a straight grid pattern, add 10% for waste from cuts. This means ordering 132 tiles instead of the base 120. For grid layouts, 10% waste is standard. Diagonal patterns need 15%, and herringbone patterns need 20%. It is always better to have a few extra tiles for future repairs than to run short during installation.
What is the best tile size for a 10×12 room?
For a 10×12 room (120.00 sq ft), 12×12 inch tiles work well. Larger tiles (12×24 or 24×24 inches) create fewer grout lines and make small rooms feel larger. Smaller tiles (6×6 or 8×8 inches) work better for bathrooms with sloped shower floors. For this room size with a straight grid pattern, 12×12 tiles would require 132 total tiles.
