Calculate the number of concrete blocks needed for your construction project. Enter the dimensions of your wall to get an estimate.
Enter the length of the wall in feet
Enter the height of the wall in feet
Enter the width (thickness) of the wall in feet
Enter valid dimensions to calculate the number of blocks needed.
This calculator uses standard concrete block dimensions of 8"×8"×16" (width × height × length) with 3/8" mortar joints.
The calculation rounds up to whole blocks, as partial blocks are typically not used. Actual quantities may vary based on specific block sizes and construction methods.
