The equation to calculate the Code 128 B bar-code
length is:
L = [ © (11) ) + 24] X
L = Length of bar code
C = Number of characters & checksum character
X = Number of Dots times 0.0033 inches per dot (0.08847
mm per dot)
The equation to calculate the Code 128 C bar code
length is:
L = [ © (11) / 2) + 24] X
L = Length of bar code
C=Numberofcharacters(roundeduptothenextevendigit)
& checksum character
X = Number of Dots times 0.0033 inches per dot (0.08847
mm per dot)
The minimum recommended height of a Code 128
bar code is 0.25 inches (6.35 mm) or 75 dots.
Ideally the bar code height should be 15% of the bar
code length. The recommend “Quite Zone” is
0.25" (6.35mm or 75 dots) or 10 times X if
larger.
