In addition to these standard sizes other unit heights lengths and thicknesses may be available from local concrete masonry producers.
Concrete block wall sizes.
Concrete blocks also come in half sizes which are helpful in reducing the need to cut blocks in the field at corners or the end of walls.
Figure 1 illustrates nominal and specified dimensions for a nominal 8 x 8 x 16 in.
Again somewhat similar to corner block concrete stretcher blocks are used to combine masonry units.

Concrete blocks are concrete masonry units or cmus but we often refer to them as concrete blocks or cinder blocks.
To better understand how the nominal size works for cmu block sizes consider the following.
The nominal size is then 4 x 8 x 8.
This is the smallest concrete block size.
Concrete masonry units cmus are manufactured in a variety of sizes.
Concrete retaining wall blocks are easy to install and ideal for building soil retaining walls reclaiming sloped land reducing erosion and even creating feature garden walls planter boxes and veggie patches.
The average concrete block is composed of cement and coal ash which is why they are often called cinder blocks.
They are identified by their depth i e.
Concrete masonry is durable hard wearing and not prone to rotting.
Blockwork and brickwork dimensions work size represents dimensions of a typical block brick used in blockwork brickwork in europe.
A wall typically requires 1 1 8 blocks per square foot.
The depth and size of the foundation will vary depending on the size of the concrete block wall and the weight it must support but a typical freestanding wall requires a foundation that is about twice as wide as the wall itself and which extends about 1 foot down below the frost line.
For instance a 6 cmu is nominally 6 deep while a 10 cmu is nominally 10 deep.
The thickness of the wall they create.
A 4 inch cmu has an actual size of 3 5 8 inch x 7 5 8 inch x 7 5 8 inch dxhxl.
203 x 203 x 406 mm concrete masonry unit.
The typical cement block measurements in certain asian countries like the philippines are actually sixteen by eight by four to six inches while a typical concrete masonry unit in the states is available in sizes of eight by eight sixteen inches.
With respect to its looks concrete stretcher block is relatively the same with common hollow block but their faces are laid parallel with respect to the face of the wall.
