Estimate grout from tile size, joint width and project area.
Enter the tiled area, tile dimensions and joint size to estimate grout quantity, bags and optional cost.
Includes your selected waste allowance.
This calculation uses tile length, width, joint width, joint depth and mixed grout density. Real consumption can change with tile profile, joint filling, surface conditions and application waste.

Estimate grout weight and full bags using the tile dimensions, joint dimensions and project area instead of relying on a single generic coverage rate.
The grout consumption rate increases as joints become wider or deeper and decreases as tile dimensions become larger.
PlanCalq calculates an estimated grout weight per unit area from tile perimeter, joint dimensions and density, multiplies that by the project area, adds waste and rounds up to full bags.
Consumption rate ≈ ((tile length + tile width) × joint width × joint depth × density) ÷ (tile length × tile width)Project area × consumption rate = estimated grout weightRecommended weight ÷ bag size = bags to buy (rounded up)Smaller tiles create more joint length across the same floor or wall area, so more grout is needed.
Use the approximate filled depth of the joint. Tile thickness alone may not equal the final grout depth.
Yes. When both calculations belong to the same saved space, PlanCalq can reuse the tile dimensions stored by the Tile Calculator.
