²Common joint sizes used with length and width dimensions. Joint thicknesses of bed joints vary based on vertical coursing and specified unit height.
³Specified dimensions may vary within this range from manufacturer to manufacturer.
The actual dimension of a unit is the dimension as manufactured. Actual dimensions may vary slightly from a specified size. The actual dimensions of a brick must fall within the range of sizes defined by the specified dimensions plus or minus the specified dimensional tolerances. Dimensional tolerances are found in the ASTM standard specifications for brick, such as ASTM C 216 Standard Specification for Facing Brick, or may be specified in the project documents.
Although nominal dimensions are given only for modular brick, it should be noted that the heights of both modular and non-modular brick are the same. This is because when modular sizes were first introduced, brick manufacturers were faced with the problem of supplying matching brick to existing non-modular construction. From an appearance standpoint, most designers required that the vertical coursing of modular brick match the existing non-modular brick. Thus, all
