Brick calculator estimates total walls area, and number of bricks to purchase for up to four rectangular and two triangular walls at a time.

Calculated numbers are accurate for building a simple brick house with gable roof. For complex masonry projects, including incorporation of a few brick patterns, or building custom designed exterior brick elements on house walls, all parameters should be adjusted based on work complexity. All computed numbers in the calculator are rounded to the nearest bigger number.

Input parameters:

1 H – Height of house wall in feet. Inches values should be entered as real number means 3 inches = 0.25 feet; 6” = 0.5’; 9” = 0.75’ and so on.

2 L – Length of house wall in feet. Input real numbers only.

3 S – Subtractions on the wall in square feet. In subtractions should be included all areas on walls which are not covered by brick, including windows and doors.

4 Brick dimensions Height x Length x Depth in inches.

5 Joint thickness or width in inches – space between bricks filled with mortar.

6 Adding an extra 10% while ordering a brick is very typical for majority of basic construction or home renovation projects. 5% might be insufficient amount because there is always a chance of transportation damages, defects or unplanned usage. While building complex custom walls waste factor could be increased up to 25% or even more.

Computed parameters:

7 Total walls area is an actual walls area in square feet which should be covered with brick excluding subtractions.

8 Number of bricks to buy for stretcher or stack bond patterns is an actual amount of bricks necessary to purchase for performing masonry project based on brick pattern. Computed number includes defined waste factor.

9 Quantity of already mixed mortar in cubic feet (ft3) and cubic yards (yd3) required for laying solid brick, accounting project size and waste factor.
