How to use the Grout Calculator
Estimate masonry grout fill volume from the number of grouted cells, approximate cell dimensions, wall height, and allowance. Enter the requested values and select Calculate. The result and supporting values are produced locally in your browser.
Formula
Worked example
Twenty-four grouted cells approximately 5.5 in by 5.5 in and 8 ft high, with 10% allowance, require about 44.37 ft³ (1.64 yd³) of grout.
What to keep in mind
- Actual CMU cell geometry varies and rebar displaces some volume; use product dimensions and project specifications.
- This estimates grout fill volume and does not determine structural grout spacing or reinforcement requirements.

Frequently asked questions
What does this calculator calculate?
Estimate masonry grout fill volume from the number of grouted cells, approximate cell dimensions, wall height, and allowance.
How is the result calculated?
Grout Volume = Cells × Cell Width × Cell Depth × Wall Height × (1 + Allowance %).
Can I use the result for an important decision?
Use the result as a calculation aid and verify the inputs, assumptions, and applicable professional or regulatory requirements before relying on it for an important decision.
Does CalculateMeasure store the values I enter?
The calculator performs its arithmetic in your browser. The calculator itself does not need to send your entered values to a server to produce the result.
