The nominal size of a modular brick is recognized as 4" x 8" x 2 2/3". This standard reflects the typical dimensions used in construction for modular bricks, which are designed to fit together efficiently and effectively while accommodating mortar joints. The nominal sizing refers to the dimensions before accounting for the actual manufacturing tolerances and the thickness of mortar that will be used in construction, which will ultimately affect the final appearance and dimension of the wall.

When considering the various choices provided, options that list sizes significantly different from 4" x 8" x 2 2/3" do not align with standard modular brick dimensions, thereby confirming that the answer is rooted in recognized industry standards. Understanding these dimensions is crucial for ensuring accurate calculations in construction projects that utilize brick, as they affect not only aesthetic considerations but also structural integrity and construction efficiency.
