Brick Sizes, Shapes, Types, and Grades
Manufacturers produce bricks to their own specifications (the same manufacturer may even produce different sizes across plants), so it is important to confirm sizes; however, the sizes in the tables below come from the Brick Industry Association and are the most commonly produced sizes.

Understanding Brick Size Nomenclature
There are three different ways of discussing sizes when it comes to brick and it is important to understand the different sizes so there isn't any confusion - we will start by discussing the different dimensions: specified, actual, and nominal.
Specified brick dimensions are the dimensions that architects use in designing a wall. Specified dimensions are the anticipated manufactured dimensions of a brick without taking the mortar joint size into account. Architects will include the specified size in their drawings and specifications. In non-modular construction, the specified size is the only size used as you'll see in the tables below — non-modular construction is uncommon.
Actual brick dimensions are the final measurements of the brick as it comes out of the manufacturing plant. The actual dimensions of the brick are within certain tolerances of the specified size — tolerances are spelled out in ASTM C216, Standard Specification for Facing Brick and ASTM C652, Standard Specification for Hollow Brick. The tolerances vary depending on the type and size of brick, but they are minimal and will usually not affect the architectural design. If you are interested in more information about tolerances, start with the Brick Industry Association Technical Notes 9A.
Nominal brick dimensions are used in modular construction and are the specified size plus the width of the mortar joint. Most bricks are manufactured so that the nominal sizes fit into a grid of 4", which coincides with the modules of other building materials such as doors, windows, and wood components.
Brick dimensions: specified sizes do not include mortar joints, while nominal dimensions include mortar joints
Brick dimensions: specified vs. nominal
Answer:
Traditional Bricks are those which have not been standardized in size. ... The commonly adopted nominal size of traditional brick is 23 cm x 11.4 cm x 7.6 cm (9”x4 ½ “x3”) approximately. Modular Bricks. Modular bricks conform to the size laid down by Bureau of Indian Standard Institution, India .
Explanation:
The standard co-ordinating size for brickwork is 225 mm x 112.5 mm x 75 mm (length x depth x height). This includes 10 mm mortar joints, and so the standard size for a brick itself is 215 mm x 102.5 mm x 65 mm (length x depth x height).
Bricks used in masonry are of two types. Traditional Bricks. Traditional Bricks are those which have not been standardized in size. The dimensions of traditional bricks vary from place to place. The length varies from 20 to 25 cm, width varies from 10 to 13 cm and thickness varies from 5 cm to 7.5 cm.
