UPC-A Size Setting

Barcode Width:
The UPC-A barcode width, W (measured in pixel), including quiet zones, can be calculated from the following expression:

UPC-A

W = ( C * 7 + 11 ) X + 2Q*

*Note: If a two-digit add-on symbol is used, W=135X+15. For a five-digit add-on, then W=162X+15.
W: width of UPC-A barcode image (including quiet zones)
X: width of UPC-A narrowest bar; (X min = 1 pixel)
C: the number of encoded data chars for UPC-A, including the check digit; C =12.
Q: width of the quiet zone; Q > = 7X; For Avapose, default Q=10X.

UP-A barcode height is not modular. According to GS1 standard, the nominal height of an EAN-13 bar code symbol is 25.9 millimeters (1.0 inch), including the human readable information. The add-on symbol should not extend outside the primary symbol height. Avapose will automatically adjust the height for you according to the specification.
