Calculate how countless bricks and also bags the mortar you’ll need for a wall surface or masonry project by beginning the wall dimensions and also selecting a brick size. Optionally, estimate the expense of products by adding the price per brick.

Bricks space a versatile structure material that are relatively small and best suited for exterior walls, chimneys, and also fireplaces. Plenty of bricks have three or an ext holes in the center to reduce the weight, raw materials, and cost.

Bricks are frequently made that clay or shale and are kiln-baked. They are frequently laid in courses or rows and also are hosted in position by laying them in a bed of mortar and filling all the joints v mortar.

The kind of brick you pick will identify how countless you need for a wall because every kind of brick is a slightly different size. The thickness of the mortar bed you use can likewise vary your material needs.

This calculator assumes a 3⁄8” mortar bed.

Calculate how countless bricks you need using the calculator above. You’ll additionally get a price estimate for materials.

You can also refer to the coverage table below or keep reading to learn how to carry out the calculations yourself.

How to calculate How countless Bricks friend Need

A wall surface built with a standard modular brick will call for seven bricks every square foot to complete the project. Projects using different sizes may need much more or less.

Follow the steps listed below for an exact estimate.

Step One: uncover Square footage of the Wall

The very first thing you should do to calculation the number of bricks you’ll need is come determine how much area you need to cover in square feet. To do this, measure the width and also height that your wall or surface.

Once you’ve measured the wall’s width and height, girlfriend can uncover the area in square footage by multiply the wall’s width in feet times the wall’s height in feet.


For example, let’s discover the area that a 10′ wide wall surface that is 8′ high.

area = 10′ × 8′ = 80 sq. Ft.

Step Two: uncover Square footage of each Brick

After you know the surface area that you need to brick, you require to uncover the area that each brick will certainly cover.

The easiest means to do that is to find each brick’s area in square inches and then divide by 144 to transform square inches to square feet. Store in mind the there will also be a 3⁄8” mortar joint in between each brick.


For example, let’s find the area of a modular brick measuring 7 5⁄8” vast x 2 1⁄4” high

To acquire the square footage of a modular brick, include 3⁄8” to each dimension to account because that the mortar joint, then use the formula (length × width) ÷ 144 = sq. Ft. That the brick.

brick & mortar width = 7 5⁄8 + 3⁄8 = 8brick & mortar elevation = 2 1⁄4 + 3⁄8 = 2 5⁄8brick ft2 = (8 × 2 5⁄8) ÷ 144brick ft2 = 21 ÷ 144 = .1458

You can likewise use a square feet calculator come easily find the square clip of her brick.

Step Three: discover How countless Bricks to fill the Wall

You have the right to determine the number of bricks required to cover her area by splitting the square clip of the area to be covered by the brick’s square clip (wall ft2 ÷ brick ft2).

For example, currently let’s uncover the number of modular bricks essential to cover the 80 ft2 wall from the previously examples. Usage the adhering to formula:

80 ÷ .1458 = 549 bricks

We strong recommend adding 10% added material come cover any type of waste and account for any kind of broken blocks or cuts.

The brick calculator above accounts because that partial bricks and also cutoffs automatically, and may return a different number for your project.

Check out our concrete block calculator to uncover the number of concrete blocks required for a project. Concrete blocks, or cinder blocks, are larger than bricks, yet the strategy to uncover the variety of bricks covering a surface have the right to be supplied to discover the variety of concrete block to covering a surface.

How much Mortar carry out you Need?

You can estimate mortar by introduce to the coverage rate for the certain mortar used on the project. Most mortar assets require one bag that cement per 100-142 bricks, depending upon the size.

One bag of cement is required for every 142 modular, 125 queen, or 100 utility bricks. This estimate assumes using a mortar that requirements to be mixed with three components sand. A 1:3 cement come sand mix will call for one yd3 that sand for every seven bags that mortar.

Pre-mixed bags of mortar are additionally readily available, and also an 80-pound bag of mix will frequently yield 30-36 bricks. Divide the total variety of bricks by 36 to calculation the bags needed. Shot our mortar calculator to calculation mortar needs more accurately.

It is crucial to keep in mind that there space many varieties of bricks and many sizes together well. See some of the most usual brick species and sizes below, in addition to an calculation of how plenty of you’ll require per square foot (or square meter).
