Grout Calculator
Estimate how much grout you need based on your tile area, tile dimensions, grout joint width, and joint depth.
How to Use the Grout Calculator
Enter the total tile area, tile length and width, grout joint width, and grout joint depth. The calculator estimates the grout volume required for the tile layout.
An additional waste percentage is included to account for installation losses and variations in the project.
Grout Calculation Formula
The estimate is based on the tile dimensions and the volume of the grout joints between the tiles.
The result is an approximation because actual grout requirements can vary with tile spacing, tile thickness, installation technique, and grout product.
Important
Always compare the estimate with the coverage information provided by the grout manufacturer before purchasing materials. Manufacturer coverage should take priority for the specific product being used.
