How to Use This Calculator

Enter Wall Length and Wall Height in feet to define the wall area.
Input Brick Length, Height, and Width in inches for your adobe block mold size.
Set the Mortar Joint thickness and Waste Factor %.
Review the number of bricks required including waste to order or produce the correct quantity.
Use the total brick count to estimate clay soil, sand, and straw ratios for your mix.

How the result changes with Wall length (ft)

Wall length (ft): Total wall length in feet.
Wall height (ft): Wall height in feet.
Brick length (in): Length of one adobe brick in inches (typical 14 in).
Brick height (in): Height of one adobe brick in inches (typical 4 in).
Brick width (in): Width / depth of one adobe brick in inches (typical 10 in).
Mortar joint (in): Thickness of mortar joints between bricks.
Waste factor %: Percentage added for breakage and cutting waste.

Identify Input Parameters
4 parameters
Wall length (ft) = 20, Wall height (ft) = 8, Brick length (in) = 14, Brick height (in) = 4 = 7 input(s) provided
Calculate Bricks required
Bricks required = ceil(bricksNeeded * (1 + wastePct / 100))
362 = 362
Calculate Clay needed
Clay needed = round((totalVolCuFt * 0.3) / 27 * 100) / 100
1.3 = 1.3
Calculate Sand needed
Sand needed = round((totalVolCuFt * 0.7) / 27 * 100) / 100
3.04 = 3.04
