Count the bricks needed for a wall including mortar joints.
Each brick plus its mortar joint occupies a measured area. Dividing the wall area including waste by that coverage, rounded up, gives the brick count. Bricks are sold individually, so including the mortar joint and a waste allowance is essential to an accurate order.
Brick Count
Bricks = area x (1 + waste) / ((brick length + joint) x (brick height + joint) / 144)
