Although brick may be built in numerous ways, depending on how it will be used, there are some countries with distinct standard brick measurements. Big bricks are heavier and more difficult to handle with only one hand while burning. But, if the bricks are small, more mortar is required. Consequently, a standard measurement is created for various brick businesses. True dimension (sometimes called stated size) refers to the real size of the brick. The nominal and real sizes of the mortar joint are equivalent. Most bricks are nominally sized to fit within a 4-inch grid; this fits well with the modules of other building materials, such as doors, windows, and wooden components.
Standard Brick Size in England
The average brick in England has always been around the same width and length, but throughout time, its depth has varied, from less than two inches (51 mm) to more than two and a half inches (64 mm). In the UK, modern bricks usually have dimensions of 215 × 102.5 × 65 mm, or about 8 5⁄8 × 4 1⁄8 × 2 5⁄8 inches. This gives a unit size of 225 × 112.5 × 75 mm (9 × 4 1⁄2 × 3 inches), with a ratio of 6:3:2, when paired with a mortar joint that is nominally 10 mm (3⁄8 inches). On Wikipedia
Standard Size Brick in American :
In the United States, modern standard bricks are regulated by the American Society for Testing and Materials, or ASTM, and measure about 8 × 3 5⁄8 × 2 1⁄4 inches (203 × 92 × 57 mm). The most often used modular brick is 7 5/8 x 3 5/8 x 2 1/4 inches (194 × 92 × 57 mm). It is simpler to figure out how many bricks to utilize in a given run when using the 7 5/8 modular brick with a 3/8 mortar connection. On Wikipedia
Standard Brick Size n Australia
According to Boral Company in Australia, the standard brick size, sometimes referred to as the working size, for the Australian Standard AS4455 is 76mm in height, 230mm in length, and 110mm in width. Some bricks need the use of several work sizes. Various structural and aesthetic effects are achieved by using bricks with diameters of 50 mm and 90 mm, 90 mm in width, and 290 mm in length. Larger bricks may be used as a focal point in the design and placed more cheaply, either by themselves or in combination with smaller bricks.
Hollow bricks are used in larger (140 mm wide x 90 mm high x 290 mm long) cyclonic zones so that wall grouting and reinforcement are possible. Wider (150 mm wide) bricks may also be used in walls that need more weight bearing capacity, less sound transmission, and enhanced fire resistance, depending on the specific brick properties.
Brick sizes in India (nominal and standard)
The typical brick size in India is 190 mm x 90 mm x 90 mm, according per BIS guidelines. The nominal size of the modular brick is 200 mm × 100 mm x 100 mm, and its dimensions expand with mortar thickness.
Standard of Bricks in Nepal
The National Building Code of Nepal (NBC 205: 1994) stipulates that the bricks must be hand-formed or machine-made, burnt red, regularly rectangular in shape, and have a minimum crushing strength of 3.5 N/mm². The higher their density and strength, the better. A brick should have dimensions of 240 x 115 x 57 mm with mortar joints that are 10 mm thick in both the horizontal and vertical directions. Thick wall tolerances of ±3 mm for thickness, -5 mm for width, and -10 mm for length are allowed under this set of Mandatory Rules of Thumb (MRT).
The Mandatory Rules of Thumb (MRT) for the National Building Code of Nepal is primarily intended to provide ready-to-use dimensions and details for various structural and non-structural elements for up to three-story, typical residential buildings framed in reinforced concrete (RC), which are commonly built in Nepal by owner-builders.
