What density value should I use for my grout?

Cementitious grout typically has a density of 1.6 kg/L and is suitable for joints 3–12 mm wide, while epoxy grout has a density around 2.3 kg/L and is recommended for joints 1–3 mm and wet areas. Match the input to the grout type on the product packaging.

How does the waste percentage affect the result?

The waste slider starts at 15% to account for grout residue left in the bucket and on tools during mixing. Increasing this percentage increases the total weight and volume output to ensure enough material is available.

Can this calculator handle different tile sizes and joint depths?

Yes, users input tile length and width in centimeters and joint depth in millimeters. The tool calculates the joint length based on the tiled area and tile dimensions, then uses the joint depth to determine raw grout volume.

Is the result in weight or volume, or both?

The calculator outputs both weight in kilograms and volume in liters, using the selected grout density to convert between the two measurements.

About this tool

What Grout Calculator does

A grout calculator that estimates the weight and volume of tile grout needed for a tiling project. Users enter the total tiled area, tile dimensions, joint width and depth, grout density, and waste percentage to receive results in kilograms and liters. The tool is designed to prevent buying too much or running out mid-project by calculating the raw volume of grout required and adjusting for typical mixing waste.

Step by step

How to use the SmartCalc Grout Calculator

1
Enter the total tiled area in square meters
2
Input tile length and width in centimeters
