# How do you calculate CMU block walls?

## How do you calculate CMU block 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.
