Brick Calculator – Estimate Bricks and Mortar

Calculate how many bricks and numberless of mortar you lot'll demand for a wall or masonry project by entering the wall dimensions and selecting a brick size. Optionally, judge the price of materials past adding the price per brick.

How Many Bricks practise you Need?

Infographic showing the most commonly used bricks and their dimensions.

Bricks are a versatile building cloth that are relatively pocket-size and all-time suited for outside walls, chimneys, and fireplaces. Many bricks have three or more than holes in the center to reduce the weight, raw materials, and cost.

Bricks are ordinarily made of clay or shale and are kiln-broiled. They are oft laid in courses or rows and are held in position past laying them in a bed of mortar and filling all the joints with mortar.

Observe Qualified Brick Masons in Your Area

The blazon of brick you lot choose volition determine how many you demand for a wall because every kind of brick is a slightly different size. The thickness of the mortar bed you lot use tin can also vary your material needs.

This calculator assumes a 38" mortar bed.

Calculate how many bricks you need using the calculator in a higher place. You'll also go a cost estimate for materials.

You tin also refer to the coverage tabular array below or keep reading to larn how to perform the calculations yourself.

How to Calculate How Many Bricks You Demand

A wall built with a standard modular brick will require seven bricks per foursquare pes to complete the projection. Projects using different sizes may need more or less.

Follow the steps beneath for an accurate estimate.

Step One: Detect Square Footage of the Wall

The get-go matter you need to practice to guess the number of bricks you'll need is to determine how much expanse yous need to cover in foursquare feet. To exercise this, measure the width and height of your wall or surface.

Once yous've measured the wall's width and height, y'all can observe the area in square footage by multiplying the wall's width in anxiety times the wall's superlative in feet.

For case, let's discover the area of a x′ wide wall that is 8′ high.

area = ten′ × eight′ = 80 sq. ft.

Step Two: Detect Square Footage of Each Brick

Later you know the area that yous need to brick, you demand to find the surface area that each brick will cover.

The easiest way to practise that is to detect each brick's area in square inches and so divide by 144 to convert foursquare inches to square feet. Keep in listen that there volition too exist a 3eight" mortar joint between each brick.

For example, allow'south find the surface area of a modular brick measuring 7 58" wide ten ii ane4" high

To get the square footage of a modular brick, add iii8" to each dimension to account for the mortar joint, and so use the formula (length × width) ÷ 144 = sq. ft. of the brick.

brick & mortar width = 7 58 + 3viii = 8
brick & mortar height = ii 1four + 38 = ii v8
brick ft2 = (8 × two v8) ÷ 144
brick ft2 = 21 ÷ 144 = .1458

You tin can also utilise a square feet calculator to easily discover the square footage of your brick.

Step Three: Notice How Many Bricks Fill the Wall

You lot tin can decide the number of bricks needed to cover your area by dividing the foursquare footage of the surface area to be covered by the brick'due south square footage (wall ft2 ÷ brick ft2).

For example, now let'southward find the number of modular bricks needed to cover the 80 ft2 wall from the before examples. Utilize the following formula:

fourscore ÷ .1458 = 549 bricks

We strongly recommend adding 10% additional cloth to cover any waste material and account for whatsoever cleaved blocks or cuts.

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

Check out our physical block calculator to detect the number of concrete blocks needed for a project. Concrete blocks, or cinder blocks, are larger than bricks, but the strategy to find the number of bricks cover a surface tin be used to find the number of physical blocks to cover a surface.

How Much Mortar do you Need?

You lot tin can judge mortar by referring to the coverage rate for the specific mortar used on the project. Most mortar products crave one handbag of cement per 100-142 bricks, depending on the size.

One bag of cement is needed for every 142 modular, 125 queen, or 100 utility bricks. This estimate assumes using a mortar that needs to be mixed with 3 parts sand. A 1:3 cement to sand mix volition require one yd3 of sand for every seven bags of mortar.

Pre-mixed bags of mortar are also readily available, and an fourscore-pound purse of mix volition often yield 30-36 bricks. Divide the total number of bricks by 36 to calculate the bags needed. Endeavor our mortar reckoner to calculate mortar needs more accurately.

Brick Coverage Table

It is important to note that in that location are many types of bricks and many sizes as well. See some of the most mutual brick types and sizes below, along with an estimate of how many you'll need per square foot (or square meter).
