Brick Calculator
Use the Brick Calculator for a transparent, instant calculation with validated inputs and cited sources. For a query such as “Brick Calculator”, enter the matching values and units below and review the stated assumptions.
How to use this calculator
Enter the requested values and units.
Review the assumptions and any warnings shown with the result.
Use the result together with the cited source and your real-world requirements.
Formula
Compute moduleAreaSquareInches = (brickLengthInches + jointThicknessInches) × (brickHeightInches + jointThicknessInches), rawBricks = wallAreaSquareInches ÷ moduleAreaSquareInches, baseBricks = ceil(rawBricks), and purchaseBricks = ceil(rawBricks × (1 + wastePercent ÷ 100)).
Worked example
Worked example: Inputs: Wall width: 20 ft; Wall height: 8 ft; Brick face width: 7.625 in; Brick face height: 2.25 in; Mortar joint: 0.375 in; Waste allowance: 10 %. Outputs: Bricks including cutting and breakage allowance: 1,207 bricks; Bricks before adding cutting and breakage allowance: 1,098 bricks.
Assumptions and limits
- The result depends on the values, units, and assumptions entered. It does not infer missing context.
