The size of a brick varies, but the standard size in India is 190 mm x 90 mm x 90 mm. This is according to the Bureau of Indian Standards (BIS) guidelines.
However, it is important to note that there is also a "nominal" or "modular" size used for bricks when considering mortar thickness. This nominal size is 200 mm x 100 mm x 100 mm. The table below provides a side-by-side comparison.
| Dimension | Standard Size (mm) | Nominal Size (mm) |
|---|---|---|
| Length | 190 | 200 |
| Width | 90 | 100 |
| Height | 90 | 100 |
Key Considerations
- Standard Size: The 190 mm x 90 mm x 90 mm brick is the size used in most construction projects.
- Nominal Size: The 200 mm x 100 mm x 100 mm size accounts for the mortar joints typically used when laying bricks. It is useful for planning building layouts and calculating material needs.
- Regional Variations: While the above dimensions are the standard size in India, brick sizes can vary by region. Always confirm brick dimensions with your local suppliers for accuracy.
- Mortar Consideration: When calculating materials, it is important to consider the thickness of the mortar. The nominal brick size already accounts for typical mortar thicknesses which is approximately 10 mm.
Practical Applications
- Construction Planning: Understanding both the standard and nominal sizes of a brick is essential for construction planning. These measurements help in:
- Estimating the number of bricks required for a project.
- Determining layout dimensions and the size of wall openings.
- Calculating the volume of mortar needed.
- Material Sourcing: When ordering bricks, make sure to specify the size you require to your supplier.
