How To Calculate Concrete Blocks Needed

These Measurements are for 8"x16" blocks and include the mortar joints. To calculate the number of blocks by a length multiply by .75, for example if the length is 400sq ft; 400sq ft x .75= 300 Blocks. Now to calculate the height (number of rows), you will multiply the height by 1.5, for example if your height is 10 ft; 10ft x 1.5= 15 blocks. To calculate the number of blocks by area multiply the area by 1.125, for example if your area is 450 sq ft; 450 sq ft x 1.125= 506 1/4 blocks. Good luck!

There are several ways you can calculate the number of concrete blocks you will need. You can calculate them by the height, the length or the area of the project you are trying to determine. For more information see here: ;
