Brick Calculator
Estimate modular brick count for a rectangular wall after openings, mortar joints, and waste allowance.
Formula
Bricks = net wall area / ((brick length+joint)*(brick height+joint)); buy quantity = ceil(bricks*(1+waste)).
About the Brick Calculator
Estimate modular brick count for a rectangular wall after openings, mortar joints, and waste allowance.
How the Brick Calculator Works
Wall and opening areas are converted to square inches, while brick face dimensions include one mortar joint in each direction.
Formula
Bricks = net wall area / ((brick length+joint)*(brick height+joint)); buy quantity = ceil(bricks*(1+waste)).
The calculation runs in your browser. Values are validated for required ranges, compatible units, and method-specific restrictions before results are displayed.

Accuracy and Limitations
Brick orientation, bond pattern, cuts, piers, wall thickness, breakage, and actual joint dimensions can change material needs.
Keep units consistent, use measurements that represent the actual situation, retain full precision during the calculation, and round only the final answer. Professional decisions may require current official rules, field measurements, laboratory methods, or specialist review.
