Building Bricks Standard Modular Size

The standard dimensions of common building bricks are defined by various national standards to ensure uniformity in construction. In India, the relevant standard for common building bricks is IS:1077 - 1992, which specifies the requirements for common burnt clay building bricks.

Standard Modular Dimensions as per IS:1077-1992

According to IS:1077-1992, the standard modular size of common building bricks, specified as Length × Width × Height ($\text{L} \times \text{W} \times \text{H}$), is:

• Length: 190 mm
• Width: 90 mm
• Height: 90 mm

Therefore, the standard modular size is 190 mm × 90 mm × 90 mm. These dimensions are crucial for designing and constructing brick masonry walls, ensuring proper bonding and consistency.

Comparing Options with Standard Brick Size

Let's compare the given options with the standard modular size of 190 mm × 90 mm × 90 mm:

• Option 1: 200 mm × 90 mm × 40 mm - This does not match the standard size.
• Option 2: 190 mm × 90 mm × 90 mm - This exactly matches the standard modular size specified by IS:1077-1992.
• Option 3: 200 mm × 100 mm × 90 mm - This does not match the standard size.
• Option 4: 190 mm × 100 mm × 40 mm - This does not match the standard size.

The standard modular size helps in easy planning and execution of brickwork, as well as ensuring compatibility with other modular building components.
