The standard size of a cement concrete block can vary, but a common size is 8 inches by 8 inches by 16 inches. This size is widely used in construction for building walls and other structural elements.
Concrete masonry unit in short form represented as CMU made of concrete, mixture of cement, sand and water. There is a form of concrete masonry unit concrete block, concrete bricks, hollow concrete block, solid concrete block, lintel block, concrete stretcher block, concrete pillar blocks, partition concrete block, corner concrete block, concrete pillar block.
Concrete block serve as economic building material and there is a wide range of Construction application for many types of Residential, Public and industrial building. Due to sturdy and long lasting building material, architect and Engineer will recommended for house construction, retaining wall, security barriers etc and this is best choice.

Whether you are planning to construct project, renovate your house, better choice is to use concrete block as construction material to lay out external or partition wall.
Concrete block is highly adaptable and versatile material resistance of fire, variety of aesthetic qualities, high structural capacity, strength, longevity, beautiful appearance, resistant to water, need minimum maintenance and economical building material, due to this it is widely used all over the world.
For the most part, in the US, we don’t use bricks to build houses or business buildings any more. smart people invented precast concrete structural unit/ modules, also known as concrete blocks used for various type of project like Residential Public building and industrial building.
What is the standard size of a cement concrete block
In many part of world, widely used in India, US, UK and other countries, concrete Masonry Units (CMUs) are manufactured in a variety of sizes. But most common, nominal size of concrete block used is 4″, 6″, 8″, 10″ and 12″ CMU full/ half block. They are identified by their depth or by their thickness of the wall they create. For instance, a 6″ CMU is nominally 6″ or 150mm deep while a 10″ CMU is nominally 10″ or 250mm deep.
Standard dimensions of concrete block
The standard dimensions for most concrete blocks are (L x H x W): 8 inches (16 x 8 x 8 inches). However, these dimensions include the length of the average mortar joint, which is 3/8 inch.

In some part of India, concrete blocks or concrete bricks are used in replacement of red clay brick due to economic and point of view, because bricks are so expensive and labor intensive that it makes good sense to not use them for building walls when other products like concrete are cheaper, faster, and better for building.
Concrete blocks come in Full and half-sizes, their half size is also available which are helpful in reducing the need to cut blocks in the field at corners or the end of walls. The architect should always attempt to design buildings using the nominal dimensions to the nearest half-block size to reduce waste and labor due to cut blocks.
Concrete block found in many shaped and size it may be solid or hollow, hollow concrete block have void known as core to reduce the weight of concrete block. Some hollow concrete block have two or three multiple Voids.
What is the size of solid concrete block
The standard sizes for most solid concrete blocks are (L x H x W): 8 inches (16 x 8 x 8 inches). However, these sizes include the length of the average mortar joint, which is 3/8 inch.
Typical nominal sizes (dimensions) for standard 4″ full solid concrete blocks are (L × H × W): 16 × 8 × 4 inch (or 400 × 200 × 100 mm) and 4″ half concrete blocks are 8 × 8 × 4 inch (or 200 × 200 × 100 mm).
In India, most commonly used, rectangular, standard size of solid concrete block is 4″, 6″ and 8″ thick CMU ( concrete Masonry unit), they are identified by their depth or by their thickness of the wall they create.

Standard size of concrete block used in India
There is two types of size used for concrete block:- 1) nominal or standard size and 2) actual size. Nominal size is represented as size of concrete block addition with mortar thickness, and their actual size is kept less than 3/8 inch or 9.5mm than nominal size to allow mortar joints between blocks.
In india, the standard sizes for most solid concrete locks are (L x H x W): 8 inches (16 x 8 x 8 inches) or 200 mm (400 × 200 × 200 mm). However, 4″ CMU, 6″ CMU, 10″ CMU & 12″ CMU are also used. These sizes include the length of the average mortar joint, which is 3/8 inch.
