What size are fireclay brick

Fireclay bricks are available in various sizes depending on their intended use and application. The most common size of fireclay brick is the standard size, which is 9 inches long, 4 1/2 inches wide, and 2 1/2 inches high (or 230 mm x 115 mm x 75 mm in metric units). These bricks are also commonly referred to as "one-third bricks" because three of them placed side by side equal the length of a standard building brick.

In addition to the standard size, fireclay bricks may come in larger or smaller sizes to suit specific needs. For example, they may be thicker or wider for increased insulation or load-bearing capacity, or thinner for use in lining furnaces or kilns with limited space.

Fireclay bricks may also be cut or custom-sized to fit irregular shapes or angles. These custom-sized bricks can be made-to-order according to the specific dimensions provided by the customer.

Overall, the size of fireclay bricks will vary depending on the intended use, and there is no one-size-fits-all answer to this question. It is important to consult with a supplier or manufacturer to determine the appropriate size and type of fireclay brick for your particular application.
