How to Calculate Brick Masonry
To calculate brick masonry, you need to determine the surface area of the planned structure by multiplying the length and height.
Then, multiply the surface area by the type of wall (e.g.
half-brick, one-brick) to calculate the total number of bricks needed.
It’s important to factor in additional bricks for piers and account for approximately 10% wastage.
Brickhunter offers a free Brick Estimation service to assist with these calculations and ensure accurate estimations, saving time and money.

Did You Know?
1. The ancient Egyptians were among the first people to use brick masonry, with evidence of its use dating back to around 3000 BCE.
2. The standard brick size used in the United States is 2 1/4″ × 3 3/4″ × 8″, but this can vary depending on the region and individual preferences.
3. To calculate the number of bricks needed for a wall, you need to account for both the vertical and horizontal spacing. This is known as the “brick and a half” rule, where you add an extra half-brick per course to account for the sawn bricks used in corners.
4. The term “frog” is often used in masonry to refer to the indentation found on the top face of a brick. Its primary purpose is to provide better mortar adhesion, enhancing the structural integrity of the wall.
5. In some regions, brick masonry is used to construct vaulted ceilings. This technique, known as tile vaulting, has been used for centuries and requires skilled craftsmanship to create complex and visually appealing designs.
Importance of Calculating Brick Masonry
Brick structures have been widely relied upon for their durability and pleasing aesthetics. However, the key to a successful brick construction project lies in accurate calculations. Calculating the exact number of bricks needed is crucial to avoid delays caused by insufficient materials or wastage of resources due to an excess supply. To achieve precise estimations and streamline the construction process, it is essential to have a thorough understanding of the principles behind calculating brick masonry.

Calculating a Single-Layer Brick Wall
A single-layer brick wall is a commonly used construction in various applications. To calculate the number of bricks needed for this type of wall, follow these steps:
- Multiply the length by the height to determine the area.
- Multiply the area by 60.
- Add 10% to account for wastage.
The final result will give you the approximate number of bricks required for the single-layer wall.
Different Types of Brick Walls and Their Purposes
Brick walls come in different widths and serve various purposes. Understanding these distinctions is crucial when calculating brick masonry. For example, a half-brick thick wall has a width of 65mm and is not suitable for load-bearing or structural purposes. However, it can be used as an exterior facade or added to a solid interior wall system for stability. Importantly, half-brick walls should not exceed a height of 500mm and may require brick piers for additional support.
On the other hand, a one-brick thick wall has a width of 215mm and consists of two layers with alternating courses of stretcher and header bricks. Stretcher courses are laid with the long edge of the brick exposed and are at least two bricks thick. Header courses, with the short side of the brick exposed, increase the structural integrity of the wall. These one-brick thick walls are recommended for structures taller than 600mm and require 120 bricks per m².
The Role and Requirements of Half-Brick Thick Walls
Half-brick thick walls are not suitable for load-bearing purposes1. However, they can be used as exterior facades or incorporated into a solid interior wall system to enhance stability1.
To calculate the number of bricks needed for a half-brick thick wall, multiply the surface area by 602. Specifically, this type of wall requires 60 bricks per m²2.
When planning for half-brick walls, it is important to take into account wastage, which is typically around 10%3.
Key points:
- Half-brick walls are not load-bearing
- They can be used for exterior facades or incorporated into interior wall systems
- Calculation: surface area × 60 (60 bricks per m²)
- Wastage should be considered at around 10%

Brick Piers and Their Importance in Structural Integrity
Brick piers, also known as pillars, play a crucial role in providing additional strength to masonry walls. They can carry beams for pergolas or serve as supports for garden gates. In the case of half-brick freestanding walls, two end piers (one on each side) are required. Intermediate piers may also be added for half-brick walls exceeding 4m in length, in addition to the end piers.
When calculating brick masonry for piers, keep in mind that a single brick pier requires an additional 14 bricks per vertical meter, while a one-and-a-half brick pier necessitates 34 bricks per vertical meter.
Precise estimation of brick requirements is paramount to avoid additional costs and project delays. By considering the surface area of the planned structure, type of wall, and incorporating necessary wastage and piers, builders can accurately determine the number of bricks needed. Utilizing Brickhunter’s free brick estimation service further simplifies this process, saving valuable time and resources. With careful calculations, brick masonry can be executed efficiently and effectively.

Frequently Asked Questions
What is the formula for calculating bricks?
To calculate the number of bricks needed for a wall, you can use the formula: Wall Area * Number of bricks per square foot = Total number of bricks. In this case, with a wall area of 144 square feet and 60 bricks per square foot, the formula would be: 144 sq ft * 60 bricks/sq ft = 2,200 bricks. This calculation assumes 9-inch thick walls and a 1/2-inch mortar joint thickness. So, to find the required number of bricks, you would multiply the wall area by the number of bricks per square foot.
How do you calculate masonry quantity?
To calculate the quantity of masonry, firstly determine the dimensions of the stones or bricks that will be used in the construction. Next, calculate the total volume of the masonry by multiplying the length, width, and height of the structure. This will provide you with the amount of masonry required in cubic units. Additionally, keep in mind any necessary adjustments for mortar or joint spacing when estimating the quantity of masonry needed.
How do you calculate cement in brick masonry?
To calculate the quantity of cement in brick masonry, you can start by determining the total volume of mortar required per brick based on the thickness of the joint. For example, if the joint is 10mm thick, the volume would be 0.0023m3.
Next, you can determine the ratio of cement to sand in mortar, which is 1:6. This means that for every one part cement, you need six parts sand. Therefore, the total quantity of cement needed per brick can be calculated by dividing the volume of mortar per brick by the sum of the cement and sand ratio, which would be 1+6 = 7.
In this case, the calculation can be done by dividing 0.0023m3 by 7, resulting in approximately 0.0003285m3 of cement required per brick.
How many bricks in 10×10 wall?
To determine the number of bricks in a 10×10 wall, we take into account a 10% wastage of bricks. Therefore, the total number of bricks required is 505 plus 10%, which equals approximately 556 bricks. This calculation takes into consideration the 4.5-inch thickness of the wall.
