Concrete Block (CMU) Sizes. Concrete Masonry Units (CMUs) are manufactured in a variety of sizes. They are identified by their depth – i.e. the thickness of the wall they create. For instance, a 6" CMU is nominally 6" deep while a 10" CMU is nominally 10" deep.
Typically, concrete masonry units have nominal face dimensions of 8 in. (203 mm) high by 16 in. (406 mm) long, although other nominal face dimensions are available that accommodate an 8 in. (203 mm) module.
Cinder blocks are a type of concrete masonry unit (CMU). Standard dimensions are set by the American Society for Testing and Materials (ASTM C90). The standard cinder block dimensions are 8 in. x 8 in. x 16 in. However, this dimension includes the length of the average mortar joint, which is 3/8 in. Standard cinder block dimensions that include ...
thickness of a concrete masonry unit is directly related to the volume of material used in its production, some unit configurations exhibit higher fire resistance ratings than others, even when the overall nominal dimensions are the same.
Thickness shown for concrete masonry is equivalent thickness defined as the average thickness of solid material in the wall and is represented by the the formula: T E = Vn L x H Where: T E = Equivalent thickness, in inches V n = Net volume (gross volume less volume of voids), in cubic inches* L = Length of block, in inches
The actual dimensions of Regular CMU blocks include depths of 3.625”-11.625” (9.2-29.5 cm), height of 7.625” (19.4 cm), and width of 15.625” (39.7 cm). The mortar in a CMU wall is typically 3/8" (9.5 mm) thick. This is the standard mortar joint thickness for CMU walls.
The sizes of CMU blocks are typically described in terms of nominal and actual dimensions. The 'nominal' dimension is the size of the block including the thickness of the mortar joint, while the 'actual' dimension is the physical size of the block itself.
CMU blocks come in a wide range of sizes, but the standard depth sizes are 4”, 6”, 8”, 10” and 12”. Each of these standard sizes come in full block and half-block sizes. Here’s a rundown of the nominal dimensions for each standard size (listed as D x H x L): 4” full block: 4” x 8” x 16”. 4” half-block: 4” x 8” x 8”.

ASTM Standards allow the actual overall dimensions a permissible variation of + or - 1/8 inch. from the specified dimension. Nominal dimensions are those used in stating the unit size. They are equal to the specified dimensions plus the thickness of the mortar joint.
