How to Estimate How Many Bricks Are Needed For a Project
Bricks are a versatile building material that are relatively small and are best suited for exterior walls, chimneys, and fireplaces. Many bricks have 3 or more holes in the center to reduce the weight, raw materials, and cost. Bricks are commonly made of clay or shale and are kiln baked. Bricks are often laid in courses or rows, and are held in position by laying them in a bed of mortar and filling all of the joints with mortar.
Estimating the quantity of bricks needed can be done with the calculator provided. You can enter the dimensions of your wall or surface and choose the type of brick you’re using and the calculator will estimate the material you’ll need. The type of brick you choose will vary the estimated quantity of bricks because each type of brick is a slightly different size. The thickness of the mortar bed you use can also vary your material needs. This calculator assumes a 3⁄8” mortar bed. Find out how much brick and masonry work costs in your area.
Calculating the Number of Bricks Needed
The first thing you need to do to estimate the number of bricks you’ll need is to determine the area that needs to be covered, in ft2. To do this, measure the width and height of your wall or surface.
Once you’ve measured the width and height of the wall, you can find the area in square footage by multiplying the width of the wall in feet times the height of the wall in feet. For example, a 10′ wide wall that is 8′ high would be 80 ft2.
After you know the area of the surface that you need to brick you need to find the area that each brick will cover. The easiest way to do that is to find the ft2 of each brick and divide by 144 to convert in2 to ft2. For example, a modular brick is 7 5⁄8” wide x 2 1⁄4” high. To get the square footage of a modular brick you would use the formula (7 5⁄8 x 2 1⁄4)/144 = .12. Our square footage calculator can easily calculate the square footage of your brick.
You can determine the number of bricks needed to cover your area by dividing the square footage of the area to be covered by the square footage of the brick (wall ft2 / block ft2). For example, to find the number of modular bricks to cover the 80 ft2 are we calculated earlier we would follow the formula 80 / .12 = 667 bricks. We strongly recommend adding 10% additional material to cover any waste and to account for any broken blocks or cuts.
The brick calculator above may return a different number of bricks for your area since it uses a more precise formula, accounting for partial bricks and cutoffs automatically.
Check out our concrete block calculator to find the number of concrete blocks needed for a project. Concrete blocks(cinder blocks) are larger than bricks but the strategy to find the number of bricks cover a surface can be used to find the number of concrete blocks to cover a surface.
Standard Brick Sizes
It is important to note that there are many different types of bricks and many different sizes as well. See some of the most common brick types and their sizes below, along with an estimate of how many bricks are needed per ft2.
