Brick Calculator

Number of bricks, cement bags and sand for a wall, for Pakistani, Indian or UK size bricks.

How this works

Bricks per m² of one leaf = 1 / ((brick length + joint) x (brick height + joint)). A 9 inch (full brick) wall has two leaves. Mortar fills the gaps, about 25 to 30% of the wall, and dry mortar = wet x 1.33.
