How to Use the Mosaic Tile Count Calculator

Running out of tiles mid-project halts your work, while buying too many wastes money. Enter your project's width and height along with a single tile's width and height, and the calculator finds the exact piece count from the area ratio. Add a waste margin suited to your pattern's complexity to cover cutting and breakage losses. Straight patterns need about 10%, complex layouts about 15%, and curved mosaic art around 20%.

Frequently Asked Questions

Why do I need a waste margin?

Cutting, breakage, and trimming around edges or curves all waste tiles, so adding 10-20% extra keeps you from running short.

Does this account for grout spacing?

This calculator uses pure tile area, so if your grout lines are wide, choose a higher waste margin to compensate.
