Calculate how numerous bricks and bags of mortar you’ll require for a wall surface or stonework project by entering the wall surface dimensions and also selecting a brick size. Optionally, calculation the price of products by adding the price every brick.

Bricks space a versatile structure material that are fairly small and also best suited for exterior walls, chimneys, and fireplaces. Countless bricks have actually three or more holes in the center to minimize the weight, life materials, and cost.

Bricks are generally made the clay or shale and are kiln-baked. Castle are regularly laid in courses or rows and also are held in position by laying lock in a bed the mortar and also filling every the joints with mortar.


The type of brick you choose will identify how numerous you require for a wall surface because every type of brick is a slightly different size. The thickness that the mortar bed you use can additionally vary your product needs.

This calculator assumes a 3⁄8” mortar bed.

Calculate how plenty of bricks you require using the calculator above. You’ll also get a price estimate for materials.

You can likewise refer come the coverage table listed below or keep analysis to learn how to execute the calculations yourself.

How to calculation How numerous Bricks friend Need

A wall surface built through a typical modular brick will need seven bricks every square foot to complete the project. Projects using different sizes may need more or less.

Follow the steps below for an exact estimate.

Step One: find Square footage of the Wall


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

Once you’ve measure up the wall’s width and height, friend can find the area in square footage by multiply the wall’s broad in feet times the wall’s height in feet.


*

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

area = 10′ × 8′ = 80 sq. Ft.


Step Two: find Square footage of each Brick


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

The easiest means to perform that is to uncover each brick’s area in square inches and also then division by 144 to convert square inches to square feet. Save in mind that there will additionally be a 3⁄8” mortar joint between each brick.


*

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

To obtain the square clip of a modular brick, add 3⁄8” come each measurement to account because that the mortar joint, then use the formula (length × width) ÷ 144 = sq. Ft. The the brick.

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


You can additionally use a square feet calculator come easily find the square footage of your brick.

Step Three: find How plenty of Bricks to fill the Wall

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


For example, now let’s discover 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 strongly recommend adding 10% additional material to cover any waste and account for any kind of broken block or cuts.

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

Check out our concrete block calculator to uncover the variety of concrete blocks essential for a project. Concrete blocks, or cinder blocks, are bigger than bricks, but the strategy to discover the variety of bricks covering a surface can be used to find the number of concrete block to sheathe a surface.

How much Mortar do you Need?

You deserve to estimate mortar by introduce to the coverage rate for the details mortar supplied on the project. Most mortar commodities require one bag that cement every 100-142 bricks, depending upon the size.

One bag that cement is required for every 142 modular, 125 queen, or 100 utility bricks. This calculation assumes making use of a mortar that requirements to be combined with three parts sand. A 1:3 cement to sand mix will need one yd3 that sand for every seven bags the mortar.

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

It is crucial to note that there room many types of bricks and also many sizes as well. See several of the most usual brick varieties and size below, along with an calculation of how many you’ll require per square foot (or square meter).
