Enter tile dimensions, joint size, and area, then click Calculate Grout.

Grout is a material used to fill the gaps (joints) between tiles, providing stability and preventing moisture penetration. The grout volume is calculated based on the total joint length, joint width, and joint depth. The total joint length is determined by the number of tiles and their perimeter. The formula is: Grout Volume = (Tile Perimeter × Tile Count) × Joint Width × Joint Depth. Then, volume is converted to weight using the grout density (typically 1.8 kg/L). A waste factor of 10% is added to account for spillage and mixing losses. This calculator helps homeowners, contractors, and tilers estimate the correct amount of grout needed for any tiling project, reducing waste and ensuring sufficient material.
