Standard Brick Size & Dimension In India

The standard size and dimension of a brick can vary depending on the country and region, but a common standard size for a rectangular clay brick used in construction is 215mm x 102.5mm x 65mm (8.5 inches x 4 inches x 2.5 inches).

This size is commonly referred to as a modular brick or a standard-size brick. The exact size and dimension of bricks can also vary depending on the manufacturer and the intended use of the brick. Some bricks may be larger or smaller or may have different proportions to meet specific building requirements.

It is important to consult local building codes and the manufacturer’s specifications to determine the appropriate size and dimension of bricks for a particular construction project.

Standard Brick Size In India

Standard Brick Size In India: 19 × 9 × 9 cm and 19 × 9 × 4 cm is the standard size of Brick which is also known as modular brick.

19 × 9 × 9 cm brick, when placed in masonry with mortar, it becomes 20 × 10 × 10 cm which is the size of a brick with mortar.

The standard size of Brick in mm is 190 x 90 x 90 mm (Length x Width X Thickness)

Standard Brick Dimensions Inches is  7.48 In X 3.54 In X 3.54 In (Length x Width X Thickness)

However, in most parts of the country, the bricks available still are 9″×4”× 3” also known as field bricks. The weight of such a brick is 3.0 kg.

The frog is provided in brick. The Purpose behind providing frogs is to form a key, to hold the mortar, so the bricks are laid with frogs on top of size 10 × 4 × 1 cm.

• For 4 cm high bricks and extruded bricks, the frog is not provided.

• The shape of brick is rectangular; it can be conveniently handled with one hand.

• The length, width, and height of the brick are as given below:

• The length of a brick is equal to twice the width of the brick plus the thickness of the mortar

Height of brick = width of the brick

Standard Brick Dimension and Size In Different Countries

Bricks are essential building materials used in construction projects worldwide. While bricks can come in various dimensions, most global construction agencies follow a standard brick size of 225 x 112.5 x 75 mm (length x depth x height) for working purposes. This standard size includes 10 mm mortar joints, resulting in an actual brick dimension of 215 x 102.5 x 65 mm.

However, different countries have their own standard brick dimensions.

In the United Kingdom, the standard modern brick size is 215 x 102.5 x 65 mm.

In the United States, the modern standard brick dimension is 203 x 92 x 57 mm, while the more commonly used modular brick has a dimension of 194 x 92 x 57 mm (length x depth x height).

In Australia, the Boral company prescribes a standard brick size of 230 x 110 x 76 mm (length x depth x height), but different-sized bricks are also produced.

In cyclonic areas, larger hollow bricks with a standard dimension of 290 x 140 x 90 mm (length x depth x height) are used.

Finally, in Bangladesh, the standard brick dimension is 9 1/2 x 4 1/2 x 2 3/4 inches (length x depth x height).

Brick Orientation

Brick is an element of three-dimension which are length, height, and width which also refer to thickness.

Although brick is three-dimensional, it can be laid in six different orientations.

When the brick is placed on its stretcher, height, and length are exposed which is called face dimension.

Brick Standard Dimension and Size

It is important to learn about what are the standard size of a brick. To avoid confusion during design and construction, it is important to know about the different dimensions.

Different Dimensions of Bricks

1. Specified dimensions.
2. Nominal dimensions
3. Actual dimensions.

1. Specified  Dimensions

• A specified dimension is defined as the dimensions of brick without consideration of mortar.
• In the rational design of brick masonry, structural engineers used them.
• Only specified dimensions are used in non-modular construction if the absence of corresponding nominal dimensions.

2. Nominal Dimensions

• In modular construction, nominal dimensions of bricks are used.
• It is the specified size plus the width of the mortar joint.
• These dimensions produce modules of 4 in. or 8 in. “,
• The building materials such as doors, windows, and wood components have same the modules, which have bricks’.

3. Actual Dimensions

• The actual dimension is defined as the measurement of bricks that is getting from the manufacturing plant of bricks.
• The actual dimensions are within a tolerance of the specified size or dimensions.
• Variation of tolerance is depending upon the type and size of bricks.
• Tolerance is given by the applicable ASTM standard specifications, such as those in ASTM C216, Standard Specification for Facing Brick, and C652, Standard Specification for Hollow Brick.

Different Types of Bricks and Their Standard Size In India

The followings are some standard brick types and Their standard size in India.

1. Modular bricks
2. Non-modular bricks
3. English size bricks
4. Conventional bricks

1. Modular Bricks

The Brick along with cement mortar joints is called Modular brick,

The standard size of brick in India, 190 mm × 90 mm × 90 mm, is The standard modular size of common building  brick with specifications (length × breadth × height)

These are machine-made bricks.

2. Non-Modular Bricks

230mm × 110mm × 70mm & 230mm × 110mm × 30mm is the size of Non – modular bricks that may be used.

3. English Size Bricks

English-size brick, which is commonly used in India is 230mm × 115mm × 75mm

4. Conventional Bricks

Conventional bricks, which are commonly used in India 230mm × 110mm × 110mm

What Is Frog

The Frog is a depression made on the top surface of bricks which is useful for making a strong bond between upcoming layers of bricks.

The Frog Should Be 10 – 20 mm Deep.

It enhances the Brick Bondings with Mortar.

The Standard Size Of Burnt Clay Bricks

The bricks are made by burning clay in a kiln. The standard size of burnt clay brick has been mentioned in IS Code.

1. Heavy Duty Burnt Clay Bricks (IS 2180)

These bricks are similar to burnt clay bricks, and they both have the same size but it has high compressive strength.

Dimension of Heavy Duty Brunt Clay Brick

The following table shows the standard dimension of heavy-duty brunt clay bricks,

Length (mm)	Width (mm)	Height (mm)
190	90	90
190	90	40

The following table shows the maximum permissible tolerance for brick dimensions,

Dimensions (mm)	Tolerance of Individual Bricks
190	+  4

190	+  7
9	+  4

3. Burnt Clay Paving Bricks (IS 3583)

These bricks contain more iron content than that ordinary clay bricks.

Excessive iron vitrification of bricks is found while burning at a low temperature, which gives a natural glaze to the brick, so which helps to make it more resistant to abrasion

From surface clay, impure fire clay, or shale, paving bricks can be manufactured. For paving bricks, shale is the best raw material. They are burned for seven to ten days continuously in the kiln.

Dimensions: The Standard Dimension of Burnt Clay Paving Bricks or Sizes are

(i) 195 × 95 x 90 mm,  

(ii) 195 × 95 × 40 mm.

Tolerances:

Dimensions  (cm)	Tolerances (mm)
195	+  6
95	+  3
90	+  3
40	+  1.5

4. Burnt Clay Soiling Bricks (IS 5779)

These are used for solving roads.

Dimension: Burnt Clay Soiling  Bricks are available in the following sizes. (i) 190 × 90 × 90 mm. (ii) 290 × 90 × 40 mm

Conclusion

In conclusion, the standard size and dimension of a brick can vary based on the location and intended use. A common standard size for rectangular clay bricks is 215mm x 102.5mm x 65mm.

When selecting bricks for a construction project, it is important to consider the local building codes and the manufacturer’s specifications.

The size and dimension of bricks can impact the ease of construction, the stability and strength of the building, and the overall appearance of the finished project.

By selecting the appropriate size and dimension of bricks, builders can ensure the success of their construction project and the longevity and durability of the finished structure.
