Grout is a dense fluid used to fill gaps between tiles, stones, and other masonry work. Calculating the right amount of grout is crucial for any tiling project to avoid running short or wasting material.
This calculator helps you determine the exact amount of grout needed based on your tile dimensions, installation area, and grout line specifications.
How to Use This Calculator

Sanded vs. Unsanded Grout
- Sanded Grout: Used for grout lines wider than 1/8 inch. It contains fine sand that helps prevent shrinkage in wider joints. Ideal for floor tiles and wider wall tile spacing.
- Unsanded Grout: Used for narrow grout lines (1/8 inch or less). It has a smoother consistency and is less likely to scratch delicate tile surfaces like marble or glass.

You should wait at least 24 hours before walking on newly grouted tile floors. For shower installations or areas that will be exposed to water, wait 72 hours before using. Full curing takes about 7 days.
Yes, you can mix different color grouts to create custom colors. However, make sure to mix enough for your entire project at once to ensure color consistency throughout the installation.
Yes, most grout (especially cement-based grout) should be sealed after installation to prevent staining, moisture absorption, and mildew growth. Wait about 72 hours after grouting before applying sealer, unless the manufacturer specifies differently.
