How do you calculate concrete blocks for walls?
Measure the length and height of the block in inches and then substitute the values in the equation square feet of block = (length of block x height of block) / 144. For example, a standard cement block measures 16 x 8 inches, so it covers 0.89 square feet — (16 x 8) / 144 = 0.89.
How much does it cost to have a cinder block wall installed?
The material cost to install a cinder block wall is typically between $3 and $5.50 per square foot, which includes the cost of the blocks themselves, mortar and structural reinforcement.
How high can you build a block wall?
It is not uncommon to create designs with an h/t from 32 to 50. That could produce wall heights of up to 33 feet for walls built with 8-inch concrete masonry units (CMU), 41 feet for 10-inch CMU, and 50 feet for 12-inch CMU. Regionally, 14- and 16-inch CMU are available, which extend possible wall heights even further.
How deep should a footing be for a block wall?
Normally a foundation wall with seven rows of blocks will be 24 inches wide and 12 inches deep and should have a footing 30 inches below grade.

How do you calculate concrete blocks?
Measure the height and width of the area where you plan to use concrete blocks. Calculate the area of the space by multiplying the height by the width. For example, if the height is 10 feet and the width is12 feet, the area is 120 square feet.
How much does it cost to lay concrete blocks?
Concrete block walls typically cost $10 to $15 per square foot to install. Consider getting several professional estimates for your wall or foundation project to get an accurate price.
How many CMU blocks are in a square foot?
Remember in the first example, the retaining wall was 10 feet high and 100 feet in length. All you do is multiply L x H = SF in this example; the answer is 1,000 square feet (SF). To find the number of 8″ x 8″ x 16″ block required, you must determine the square footage of one CMU which is .89 SF per block.
