The brick size will vary based on different country standards. The standard size of brick has been mentioned in IS code 1077.
In general, there are four standard sizes of bricks used in India.
There are other dimensions also based on the locality. The weight of the bricks should not exceed 3 kg.
In India, Bricks are made by burning clay in a kiln. Standard Size of Burnt Clay Brick has been mentioned in IS: 2691:1988 Revision 2 (Clause 4.1 & 4.2) as 190 x 90 x 90 mm.
Length of the brick = 2 x Width of brick + mortar
Since we can’t produce every brick at accurate dimensions, there are tolerances on dimensions
A dent provided on the top side along the length of the bricks is known as a frog. The frog should be 10-20 mm deep.
As you know bricks are burnt in kilns. If the sizes increase, it will be hard to burn them properly. It would be baked half like the inside of a samosa.
For the workability, the bricks are made in a standard size. So that the mason can easily lift and place the bricks in proper. If we increase the size, it will become challenging to attain high accuracy on the wall dimensions. The same happens on Concrete Blocks.
The other reason is that the bricks are made to match the column size. We generally conceal the columns along the brick walls. For Example, the 9” inch brick walls will conceal the 9×9” column entirely and give a pleasant appearance.
We discussed the same here – https://civilplanets.com/square-or-rectangular-or-circular-column/
Moreover, we can quickly check the qualities of good bricks in the field. Hence we can choose the right brick for construction activities.
The standard size of bricks for different countries has been mentioned in the table below.
Country | Size of the Brick |
London | 215mm x 102.5mm x 65mm |
USA | 194mm x 92mm x 57mm |
Australia | 230mm x 110mm x 76mm |
Romania | 240mm x 115mm x 63 |
Russia | 250mm x 120mm x 62mm |
Sweden | 250mm x 120mm x 62mm |
South Africa | 222mm x 106mm x 73mm |
Germany | 240mm x 115mm x 71mm |
Denmark | 228mm x 108mm x 54mm |
Bangladesh | 241mm x 114mm x 70mm |
