The standard size for bricks used in construction is typically 220mm x 105mm x 75mm. These dimensions provide a good indication of the size and coverage area of bricks when estimating quantities.
Other Brick Shapes and Sizes
In addition to standard bricks, there are several other shapes and sizes available. These include bullnose bricks, capping bricks, and specialty bricks. These variations may have different dimensions and coverage areas than standard bricks. When estimating the brick quantity, be sure to consider the specific dimensions of the bricks you plan to use.
By familiarizing yourself with the common brick dimensions, you can make more accurate estimations for your projects.
Common Brick Patterns
The choice of brick pattern can significantly impact the overall aesthetic appeal of your project. Let’s explore some of the commonly used brick patterns.
Stretcher Bond
Stretcher bond is one of the most basic and commonly used brick patterns. It involves laying bricks in a running bond, with each brick overlapping halfway on the one below. This pattern provides a clean and simple look suitable for various projects.
English Bond
The English bond pattern alternates courses of stretchers and headers. A stretcher refers to the long face of the brick, while a header refers to the short face. This pattern is known for its strength and durability and is often used in load-bearing structures.
Flemish Bond
The Flemish bond is similar to the English bond, but with alternating headers and stretchers within each course. This pattern provides a more intricate and decorative appearance and is often used in historic or high-end projects.
Stack Bond
In a stack bond pattern, bricks are laid directly on top of each other without any overlapping. This pattern creates a modern and minimalist look, but it is essential to consider the structural implications when using this pattern in load-bearing applications.
Basket Weave
The basket weave pattern consists of pairs of bricks laid horizontally and vertically, creating a woven appearance. This pattern adds texture and visual interest to projects, making it a popular choice for pathways and patios.
Herringbone
Herringbone is a classic pattern that involves placing bricks at a 45-degree angle in a zigzag pattern. This pattern is often used in driveways or high-traffic areas, as it provides additional strength and stability.
Running Bond
Running bond is similar to the stretcher bond, with bricks laid in a running pattern. However, in a running bond, the end of each brick aligns with the center of the brick above or below it. This pattern is versatile and commonly used in various projects.
Common Bond
Common bond is a pattern that combines the stretcher bond and header bond. It involves alternating courses of stretchers and headers, typically with more stretchers than headers. This pattern provides a good balance of strength and aesthetics.
Diagonal Bond
In a diagonal bond pattern, bricks are laid at a 45-degree angle, creating a visually striking herringbone effect. This pattern adds a unique and dynamic look to projects, making it a popular choice for accent walls or focal points.
By familiarizing yourself with these common brick patterns, you can choose the one that best suits your project’s aesthetic requirements.

- Height: 2.5 meters
Assuming the standard brick size mentioned earlier (220mm x 105mm x 75mm) with a 10mm mortar joint and a 7% wastage allowance, here’s how you would calculate the brick quantity:
- Calculate the total wall area: 6m x 2.5m = 15 square meters.
- Determine brick coverage area: Given the standard brick size, the coverage area is 0.02205 square meters (220mm x 105mm).
- Adjust for mortar joints: Assuming a 10mm mortar joint, divide the coverage area by the adjusted brick size (0.02205 – (0.01 x 0.01)) = 0.02185 square meters.
- Calculate the quantity of bricks needed: Divide the total wall area by the adjusted brick coverage area: 15 square meters / 0.02185 square meters = 686.14 bricks.
- Account for wastage: Multiply the calculated brick quantity by the wastage allowance (686.14 x 7%) = 48.03 bricks.
In this example, you would need approximately 734 bricks (686.14 + 48.03) for the wall construction, taking into account the different factors discussed earlier.
Paving Example
Suppose you plan to create a paved patio with the following measurements:
- Length: 4 meters
- Width: 3 meters
Assuming the same standard brick size and wastage allowance as the previous example, here’s how you would calculate the brick quantity:
- Calculate the total paving area: 4m x 3m = 12 square meters.
- Determine brick coverage area: Using the standard brick size, the coverage area is 0.02205 square meters.
- Calculate the quantity of bricks needed: Divide the total paving area by the brick coverage area: 12 square meters / 0.02205 square meters = 544.42 bricks.
- Account for wastage: Multiply the calculated brick quantity by the wastage allowance (544.42 x 7%) = 38.11 bricks.
In this example, you would need approximately 582 bricks (544.42 + 38.11) for the paved patio, considering the different factors involved.
