Calculating the Required
Number of Standard Construction Blocks
Block producers are
often asked how many standard blocks are needed for a project. In
addition, the measurements can be either imperial or metric. The table
below provides a very fast, simple and accurate way to find the answer.
IMPERIAL
MEASUREMENTS
Length
To calculate the number of
construction blocks by a specific length:
Multiply the length by .75 Example: 140 ft. x .75 =
105 blocks (includes the mortar joints)
Height
To calculate the number of rows
of construction blocks by a specific height:
Multiply the height by 1.5 Example: 8 ft. x 1.5 = 12
rows (includes the mortar joints)
Area
To calculate the number of
construction blocks by a specific area:
Multiply by 1.125 Example: 160 Sq. Ft. x 1.125
= 180 blocks (includes the mortar joints)
METRIC
MEASUREMENTS
Length
To calculate the number of
construction blocks by a specific length:
Multiply the length by 2.5 Example: 50 M. x 2.5 = 125
blocks (includes the mortar joints)
Height
To calculate the number of rows
of construction blocks by a specific height:
Multiply the height by 5 Example: 3 M. x 5 = 15
rows (includes the mortar joints)
Area
To calculate the number of
construction blocks by a specific area:
Multiply by 12.5 Example: 16 Sq. M. x 12.5
= 200 blocks (includes the mortar joints)
