Code 39
(Code 3 of 9)
Code 39 is an alphanumeric bar code. Each charac
-
ter consists of 5 bars and 4 spaces. 3 of the 9 bars or
spaces are wide. The wide to narrow bar and space
width is set by the ratio. The minimum narrow
bar or space is 3 dots or 0.010 inch (0.254
mm).
The supported ratio of narrow bar to wide bar
widths are: 2:1, 5:2 (2.5:1), and 3:1. The equa
-
tion to calculate the Code 39 bar code length is:
L = [ (C+2) (3R + 7) - 1] X
L = Length of bar code
C = Number of characters
R = Ratio of wide to narrow bars
X=Number of Dots times0.0033inches per dot (0.0847mm
per dot)
For the 5:2 ratio, the X = Dots times 2
The specified minimum
recommended height of a
Code 39 bar code is 0.25 inches (6.35 mm) or
75 dots. The recommend “Quite Zone” is 0.25"
(6.35mm or 75 dots) or 10 times X if larger.
