The line measurement method is another process for measuring copy to fit
into a predetermined space.
To use the line measurement method, use this table:
Measure a distance from the left margin of the copy and draw a line
down the right side of the paper.
Multiply the distance from the left margin to the drawn line by:
10 (pica; 10 elements per inch) or
12 (elite; 12 elements per inch)
Measure the depth of the copy by multiplying page length by:
6 (single spaced copy) or
3 (double spaced copy)
Multiply the number of lines by the number of characters per
average line to find the number of characters on the page.
Add this number to the number of characters in the long lines that
run beyond the drawn line on the right of the page.
Subtract the number of characters required to fill short lines. The
result is the total character count for the page.
