How many bricks in a square foot. In order to calculate how many bricks you’ll need, you want to measure your wall construction area.
If you plan to follow the standard modular brick building pattern, any dimensions should work equally as well.
Standard modular patterns will require seven bricks per square foot in order to complete the project.
Some projects may require more or less depending on their size; just be sure to factor these potential discrepancies into account when planning how much material you’ll need overall and adjust based on what works best for your design.
Once you have an accurate measurement of your wall’s surface area and have established a modular pattern preference, consult the calculations below for absolute estimates:
How many bricks in a square foot
No matter the nature of a brickwork project, calculating the number of bricks per square foot helps determine how many bricks are needed for the project as a whole.
You also need to know the square footage of the area where bricks will be laid, such as on a wall or patio.
If you know these two figures, you can calculate approximately how many bricks you will need.
Then add 5–10% more as an additional buffer in case damaged or broken bricks occur during installation which is very common with retaining walls.
First Step
Using a tape measure, find out how deep the brick is (depth) and how tall it is (height).
If you plan to install the brick facing their broadside up, you can simply add twice the depth of the brick + twice the height of the brick.
For example: A 2-inch deep by 4-inch high brick = 2 inches (depth) + 4 inches (height), so 8 inches total.
If you plan to install them with their front faces exposed, multiply your findings for length by width instead: A 3-inch wide by 7-inch high brick would have a volume of 3 x 7 = 21 cubic inches.
Second Step
Shake a standard box of bricks in order to determine the number you will be using. Divide the total number of bricks by the total number of square feet to get your brick-to-square-foot ratio.
If there are 26 bricks, for instance, and you plan to install them on 200 square feet, your brick-to-square-foot ratio is 8.6 (26 divided by 200).
Third Step
To figure out the square footage of a large space, measure the length and width of the space if you have a rectangular room, 60 feet by 30 feet, for example, multiply both numbers to get the square footage: 30 × 30 = 900 square feet.
If you have an irregularly shaped room such as trapezoidal or circular, you need to measure along several wall lengths and then add them together.
Fourth Step
Determine the number of bricks needed for the job by multiplying the square footage by how many bricks are in each square foot (4.5) and then subtracting a 10% buffer.
For this instance, 540 bricks are needed. Keep in mind a few spoilt ones might slip through, so ensure you purchase more than that calculated final amount.
A project such as a patio or a walkway requires mortar between all the bricks to keep it together but can vary depending on which type of brick is being used and what sort of material is it is constructed from.
If, however, only one wall needs building instead of a whole back patio wall or outdoor kitchen counter, instructions will be given at this point on how much mortar to buy with the bricks for that specific type of cornering required for example if inside corners are used instead of outside then obviously adjustments need to be made.
