One of the most critical aspects of any brickwork project is determining the number of bricks required. This estimation should be as accurate as possible to avoid wasting materials, time, and labor.

In this section, we will explore how to use standard brick dimensions to calculate the number of bricks needed for a project and why it is essential to order extra bricks.

Using Standard Dimensions to Calculate the Number of Bricks Needed

Calculating the number of bricks needed for a project involves the estimation of the needed wall area and taking into account the waste factor. To estimate the wall area to be covered, measure the height and length of the wall, and multiply them.

Once you have calculated the wall’s surface area, take into account the size of the bricks, including the mortar’s thickness, to determine how many bricks are needed per square meter. For example, if the wall area is 20 square meters with a brick size of 230mm x 114mm x 76mm and a mortar thickness of 10mm, the number of bricks needed will be:

1.20 meters height x 10 meters length = 20 square meters


To account for the mortar thickness, the total area of each brick will be (240mm x 120mm) = 0.0288 sq meters

3. Divide the wall area by the area of one brick to get the total number of bricks needed: 20 sq meters / 0.0288 sq meters per brick = 694.44 bricks


Add a waste factor of around 10% to this figure to account for breakages and errors: 694.44 x 1.10 = 764.88 bricks. In this example, 764.88 bricks will be required to complete the 20 square meter wall area.

Importance of Ordering Extra Bricks

Ordering extra bricks is essential for a successful brickwork project. During the project, some bricks may get damaged or break due to transport, cutting, or other factors.

Even with careful planning, estimation,variations in construction, or calculation errors may occur,resulting in the need for more bricks than initially anticipated. Furthermore, in the event that the project requires modifications or additions over an extended period, some bricks might be discontinued, and it may become challenging to find a suitable match.

In such cases, having extra bricks on hand, with the same color, texture, and standard dimensions, will make repairs and modifications much easier. Therefore, it is crucial to order extra bricks, typically 10% to 15% above the estimated needed amount, to avoid delays, additional expenses, and ensure excellent results and problem-free construction projects.
