Brick Calculator

Estimate the number of bricks needed for a wall from its net wall area, brick face dimensions, mortar-joint thickness and waste allowance. The calculator also provides a rough mortar-bag count using an adjustable bricks-per-bag assumption, so you can replace the default with the coverage information for the mortar product you plan to use.
