Here are the Top 3 issues that you should keep in mind when selecting a block shape:

​

1.  The most common block size is 8x8x16, (WxHxL), however, the most common shape is a double-open-end-bond-beam unit, also referred to as an 08-08-16DOEBB.  While it is helpful to know the most common block sizes, it should by no means limit your consideration of other block sizes. Also, multiple block shapes can be used in the same wall, including differences in width, height and length.

​

2. While solid caps can be made 2" High and 4" high, block is typically either 8" or 4" high. It is NOT an option currently, however, to manufacture a 6" high CMU. The 4" tall CMU can have a look and feel similar to clay brick, yet is installed just like regular CMU. 

3. Block shapes are determined by a combination of the mold, and additional internal mold parts, all of which affects the width, height and length, as well as the size and position of any cavities in the block. While there are currently 100's of shapes available, new shapes can be made simply by creating a new mold. Some of the more popular new block sizes include a 24" long unit, 4" tall units that emulate brick, 1" and 3" wide solid veneer units, as well as some specialty shapes, including Ship Lap.
