Standard 2 of 5
(Code 2/5)
The Two of Five code symbology encodes all infor
-
mation in the width of the bars. None of the infor
-
mation is carried by the spaces. Bars are wide or
narrow and the wide bars are set by the ratio.
Spaces are the same width as the narrow bars.
Two of Five code supports the numeric characters:
0123456789
The supported ratio of narrow bar to wide bar
widths are: 2:1, 5:2 (2.5:1), and 3:1.
The equation to calculate the Code 2/5 bar code
length is:
L=[(C(2R+8))+14]X
L = Length of bar code
C = Number of characters
R = Ratio of wide to narrow bars (5:2=2.5)
X = Number of Dots times 0.0033 inches per dot (0.08847
mm per dot)
For 5:2 ratio, the X = Dots times 2
The specified minimum
recommended height of a
Code 2/5 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.
