Tile Calculator

For standard straight installations, add 10% for waste and future repairs. For diagonal patterns, complex layouts, or rooms with many corners, add 15% or more. It's always better to have extra tiles than to run short.

For rectified tiles (uniform size), use 1/16" (1.6mm). For standard floor tiles, use 1/8" (3mm). For natural stone or irregular tiles, use 1/4" to 1/2" (6-12mm). Always check the tile manufacturer's recommendations.

Yes! This calculator works for both floor and wall tiles. For walls, you may need to account for trim pieces at edges and corners. Wall tiles typically use narrower grout gaps (1/16") compared to floor tiles.

For overlapping tiles (common in roofing or siding), enter a negative value for the grout gap. For example, if tiles overlap by 1 inch, enter -1. The calculator will adjust the coverage area accordingly.

Popular tile sizes include: 12"×12" (most common), 18"×18", 24"×24" for large format, 6"×6" and 8"×8" for smaller spaces, and 3"×6" subway tiles. Square tiles are easiest to install, while rectangular tiles can make spaces look larger.

Absolutely! Tile batches can vary in color and finish. Even with the same product code, tiles from different production runs may not match exactly. Buy at least 10% extra and keep them in storage for future repairs.
