Brick Size report
Brick is a common building material. The oldest brick-making technique can be traced back to about 9,000 years ago when the first batch of bricks was made around Jericho's walled city in southern Turkey and the West Bank. Bricks come in different types and sizes, and brick dimensions can vary. Various types of brick can be used for construction projects, including bridges, buildings, pavement, etc.
Brick size is a standardized size used by brick manufacturers to ensure consistent and reliable products. In theory, a mason using bricks can determine the required coverage and the desired appearance and then order a certain number of bricks based on the fixed size required for the job. However, the brick size is very complicated, and even though it should be standardized, it is not the case.
The first thing to be aware of when buying a brick is the size of the brick, and the size of the brick varies from country to country. Since the size of bricks is not standardized internationally, it is best to ask brick manufacturers to give the size of their products when placing an order.
Understanding Brick Dimensions
It is essential to know about the different dimensions to avoid confusion during construction. When discussing brick sizing, there are three kinds of sizes that can be referenced:
- Specified dimensions: The specified dimensions are defined as the dimensions of brick without considering mortar. These are used in the project specifications, purchase orders, and when working with non-modular bricks.
- Actual dimensions: The actual dimensions are the specified size plus the width of the mortar joint. Once it is manufactured, they are the dimensions of brick: the actual end product.
- Nominal dimensions: Nominal dimensions, typically expressed in round numbers, include the mortar thickness.

Standard Brick Sizes by Country
Standard brick sizes vary from country to country, with dimensions including depth x height x length. Standard brick dimensions may be expressed in either imperial units, in terms of inches, or metric units, as millimeters. The following are the specified dimensions of standard bricks in a few different countries.
Country | Brick Size in Inches (D x H x L) | Brick Size in Millimeters (D x H x L) |
---|---|---|

Bricks are used in various construction and other ways, and the different fields need a different size of a brick, different shape, different formation is also required. We hope that the above information will help you understand the different brick sizes further.
