Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Net wall area = length × height − openings. Unit module = (unit length + joint) × (unit height + joint). Units = round up (net area ÷ module area × waste factor).
FAQ
Brick & Block Calculator questions
Should mortar joints be included?+
Yes. The visible module includes each brick or block plus the mortar joint, which changes units per square foot or metre.
How much masonry waste should I add?+
Five to ten percent is common for simple walls. Corners, patterns, damage and many cuts may require more.
Does this calculate structural reinforcement?+
No. Reinforcement, lintels, foundations and wall design require project-specific engineering and local-code review.
