Cubic Meter to Brick Calculator (Pieces Estimator)
Estimate the number of bricks required per cubic meter of masonry. Includes UK, US Modular, and Metric brick standards with mortar joint logic.
About
Ordering masonry materials is rarely as simple as calculating geometric volume. A cubic meter of wall contains both bricks and mortar, and the ratio depends heavily on the brick format and joint size. Ordering based on pure brick volume leads to massive oversupply, while ignoring breakage leads to shortages. This tool calculates the precise number of brick units required to fill a cubic meter, factoring in the standard mortar bed.
Designed for site managers and DIY home builders, the calculator supports international standards including UK Standard, US Modular, and Euro Metric sizes. It distinguishes between the volume of the brick itself and the volume of the installed unit (brick + mortar), providing a realistic count for purchasing.
Formulas
The calculation considers the "Working Size" of the brick, which is the brick dimension plus the mortar joint width.
Note: This assumes a single-leaf wall or solid fill. Double-skin walls may require doubling the count depending on how the input volume is measured.
