Tile Grout Calculator

Estimate how much grout you need for a tiled area from tile size, joint width and joint depth.

Estimate only — not a substitute for a licensed tradesperson, a certified engineer, or sign-off from your local building surveyor. Verify against current standards and site conditions before ordering materials or starting work.

building rules differ by state, territory and council. Results are estimates - confirm requirements with your local council or state building authority before you build.
