Measure walls and openings
Subtract actual doors and windows from the wall face before multiplying by thickness. Overlapping openings should not be double-counted.

UNDERSTAND YOUR RESULT
Understand Your Wall Material Quantity
Start with wall dimensions, subtract openings, and choose the actual brick or block size. Mortar joints and waste change the quantity you may need.
Choose brick or block size
The brick plus mortar joint defines the repeating module. Different blocks need their own measured dimensions.
Review pieces and waste
Review the displayed breakdown and assumptions before using this estimate.

What changes your result?
- Deduct openings once. Subtract actual doors and windows from the wall face before multiplying by thickness. Overlapping openings should not be double-counted.
- Use modular dimensions. The brick plus mortar joint defines the repeating module. Different blocks need their own measured dimensions.
Assumptions and limits
Confirm measurements, inclusions and price assumptions. These planning results do not replace professional engineering, legal or lender advice.
Results retain the assumptions you selected. Compare like-for-like areas and avoid counting the same item twice.

Net wall V=(L×H−openings)×thickness; module=(brick L+joint)×(brick W+joint)×(brick H+joint); count=ceil(V/module×waste factor).
Currency totals: 2 decimal places; geometry and quantities: 6. Whole units/boxes round upward with floating-point ULP correction; internal calculation precision is retained.
