Grout Calculator
Estimate grout from the tiled area, tile dimensions, tile thickness and joint width. Use your product data when a manufacturer provides a more specific coverage rate.
Geometry-based estimate
The tool uses tile perimeter, tile face area, joint width, tile thickness and a density factor to provide a planning estimate. Actual product yield can vary, so manufacturer coverage data should take priority when available.
Why joint dimensions matter
Wider or deeper joints hold more grout. Smaller tiles also create more joint length over the same surface area than larger tiles.
