Interleaved 2 of 5 Size Setting

Size setting overview
This page is on size setting of Interleaved 2 of 5, emphasizing 2 important factors: barcode width and height.

Barcode structure
The components of Interleaved 2 of 5 include a leading quiet zone, start pattern, one or more pairs of symbol characters representing data (including check character, if present), stop pattern and a trailing quiet zone.

Barcode Width:
The Interleaved 2 of 5 barcode width, W (measured in pixel), including quiet zones, can be calculated from the following expression:

Interleaved 2 of 5

W = [ P (4N + 6 ) +N + 6 ) ] X + 2Q

W: barcode width of Interleaved 2 of 5. X: width of Interleaved 2 of 5 narrow bar; (X min = 1 pixel) N: the wide bar to narrow bar ratio; (2.0<=N<=3.0) P: the number of character pairs. Q: the width of the quiet zone; (Qmin= 10X)

Barcode Width:
The Interleaved 2 of 5 barcode width, W (measured in pixel), including quiet zones, can be calculated from the following expression:

Interleaved 2 of 5

According to ISO/IEC 16390:2007 (E), there are no detailed requirements for Interleaved 2 of 5 barcode height. However, there is a recommended minimum bar code height for manual scanning, i.e. 5.0 mm or 15% of symbol width excluding quiet zones, whichever is greater.
