Estimate masonry units, mortar bags, and full pallets for brick, concrete block, or CMU walls.
Measure equal wall sections together and subtract the combined area of doors, windows, and other openings.
The unit face plus mortar joint creates a module that may differ from the brick or block's nominal name. Bond pattern, corners, returns, sills, lintels, bond beams, cuts, and special shapes can change both units and mortar.
module = (unit length + joint) × (unit height + joint)units = waste-adjusted wall area ÷ module areaIncluding the mortar joint in the module prevents the calculator from treating every course as tightly stacked units.
Verify actual unit size, mortar coverage, pallet quantity, bond, reinforcement, flashing, drainage, and structural requirements with the plans, supplier, and local authority. This is a material estimate, not a wall design.
