How to Use This Calculator

Enter your tile area and tile dimensions. Select grout joint width (1/8" common for floor, 1/16" for wall) and tile thickness. Calculator accounts for waste.

Why Accurate Grout Matters

Grout requirements vary significantly with tile size and joint width. Larger joints and thicker tiles use substantially more grout. Accurate estimates prevent mid-job shortages or excessive waste.

Common Mistakes to Avoid

Underestimating joint width, not accounting for tile thickness, mixing too much at once (1-hour working time), and not sealing grout after curing.
