Designing in Brick - Brick Sizes

Designing in Brick Series:  Brick Sizes

Brick is one of the oldest and most common building materials used in the world. There are several different types of brick, each available in a variety of sizes, because we recognize the needs of building designs will vary in terms of functional requirements, aesthetic requirements, and local building codes.

Below we’ll break down four of the most common brick sizes used in residential construction so you can decide which size of brick is most appropriate for your home style. Regardless of the size selected, your new brick home will provide the same unbeatable benefits of brick that no other building material can offer… for a lifetime and beyond.

modular brick


Modular brick is the most common brick size used in North America. Modular brick dimensions are 3-5/8 in (thickness) x 2-1/4 in (height) x 7-5/8 in (length).


Architects, designers, and builders will have the widest selection of color and texture available when selecting a brick in modular size. Another benefit is the ability to create more efficient layouts that minimize the number of brick that need to be cut in order to accommodate design parameters. A larger selection of non-custom shapes are also available in modular size brick than any other brick size.


It takes 6.86 brick to cover each square foot of wall area when designing with a modular size unit. Using a typical 3/8 mortar joint, mortar will account for approximately 20% of the wall with a modular size brick, as the brick size increases, the percentage of mortar is reduced.

queen brick


Queen size brick measure 3 in (thickness) x 2-3/4 in (height) x 7-5/8 in (length) and lay 5.76 brick per square foot. A queen size is particularly popular among residential building because it is more cost efficient to install. Given the larger unit, queen size brick install faster and require less mortar.

When coursing out a queen size wall it takes five courses (rows) for every 16 inches vertically while a modular brick takes six courses (rows) for every 16 inches. In general, larger brick require fewer brick to lay and fewer joints to tool.

handmade brick


Handmade Oversize brick are a unique and aesthetically pleasing brick selection. Each brick is crafted individually by hand to reveal the true artistry of a classic material with endless contemporary applications. No two handmade brick look identical, and that’s exactly why they remain one of the most premium and sought-after brick products available. Glen-Gery’s line of handmade brick is rich in character and adds variation to any design. The classic charisma of this brick is matched only by its versatility and ability to enhance any residential or commercial project.


Handmade oversize is 4 in. (thickness) x 2-3/4 in. (height) x 8-1/2 in. (length) and take 5.9 brick to cover a square foot of space, a larger unit than a modular brick. These brick are also 100% solid units, without core holes.

roman max


With a nominal length of two feet long, the Roman Maximus evokes feelings of sophistication, exclusivity, and prestige. Roman Maximus brick is characteristically longer and more linear than those of typical modern brick. They are ideal for creating a regal and distinct look to any structure.


The Maximus size measures at 3-5/8 in (thickness) x 1-5/8 in (height) x 23-5/8 (length) in and takes 3 brick per square foot. The Roman Maximus product by Glen-Gery is unique because it is packaged with more than just a single size brick. Seventy percent of the packaging for a Roman Maximus product is at the 23-5/8 in length, fifteen percent is at Roman size which is 3-5/8 in x 1-5/8 in x 11-5/8 in and the balance of the packaging is random lengths from 4 in. to 20 in. This packaging enables the mason to install the brick where no two joints align, called a Sicilian bond.

Speaker Series: Beyond Style with Grant F. Marani

RAMSA Partner Grant F. Marani hosted a lecture hosted at the Brickworks New York Design Studio, where he discussed brickwork traditions that have influenced his practice as an architect as well as two of his projects—the Immanuel Chapel at Virginia Theological Seminary and the International Quilt Museum in Lincoln, Nebraska. By pairing a chapel evoking ecclesiastical forms with a museum featuring a modern patchwork of texture and color, Marani will posit that brick’s materiality is inherently liberating rather than limiting; brick is beyond style.

Enhanced Design Visualizer Tool Inspires + Simplifies

Designers, architects and homeowners can create a picture perfect home or building using Glen-Gery’s newly enhanced Virtual Design Tool, fully loaded with Glen-Gery products and colors.

Major technology upgrades to the tool allow a user to “See it before you live it,” choosing a home style that best matches their vision then applying product to fully visualize the outcome.

No problem, simply use the search to find product name.

To help visualize brick or stone styles on a building, the website offers three options:

    Use one of our pre-loaded commercial or residential images.

    Upload and prepare a custom image with auto-mask

    Have us professionally mask a custom image for a small fee.

According to Denise Smith, Marketing Manager, the tool is used mostly for residential design as architects have their own rendering software to realize commercial building design.

“With over 600 Glen-Gery products to choose from, the selection process has been overwhelming in the past,” she said. “The enhanced user interface and updated tool makes it much easier to select a product and apply it to all a home.”
