How to Use This Calculator

Enter the tile length and width in millimeters from the tile specification sheet.
Enter the grout joint width in mm — the spacer size you are using (e.g., 3 mm).
Enter the grout depth in mm — typically 4 mm below the tile surface edge.
Enter the total tiled area in square meters.
Read the grout volume in liters and the number of approximately 5 L bags to purchase.

How the result changes with Joint (mm)

Tile length (mm): Length of a single tile in millimeters. Common sizes: 300, 600, 900 mm.
Tile width (mm): Width of a single tile in millimeters. For square tiles, enter the same value as length.
Joint (mm): Spacer width.
Grout depth (mm): Below edge.
Area (m²): Total area to be tiled in square meters. Measure the floor or wall surface.
