as recommended by GS1
Barcodes formerly know as EAN, JAN or UCC types are now called GS1 barcodes
If you are creating barcodes for use in a retail environment (eg. GS1/EAN-13 or UPC-A) then you should consider the size of the barcode. The recommended barcode sizes shown below provide the sizes you would use for creating the barcode at 100% of the nominal size recommended by GS1. GS1 typically permits the size the range between 80 - 200% of this nominal size, and that means when both the height and the width of the image vary by the same proportion. If you need to truncate* the barcode to fit on small packaging you are advised to check that the resellers of your products find this acceptable (in our experience many will, but some won't!).
|Type||X value (Mils)||Height (mm)||permitted range %|
|GS1-8||13||18||80 - 200%+|
|GS1-13||13||22||80 - 200%+|
|GS1-14#||40||30||80 - 200%|
|GS1-128||40||30||25 - 120%; minimum height 20 mm|
|ITF-6||40||30||62 - 120%|
|ITF-14||40||30||62 - 120%|
|SSCC||40||30||50 - 84%|
|UPC-A||13||22||80 - 200%+|
|UPC-E||13||22||80 - 200%+|
# GS1-14 numbers are normally produced as GS1-128 barcodes, but
may be created as the ITF-14 barcode type.
+ These ranges require that both the height and width (or X value) are modified in the same proportion.
*Truncation of a barcode symbol is the reduction of the barcode symbol height relative to the width. Truncation is not recommended because it destroys the ability of a symbol to be scanned omni-directionally at the point of sale. A truncated symbol can only be scanned when the trade item is oriented in particular directions across the scanning beam. Truncation therefore reduces checkout efficiency. The more the height is reduce the more critical becomes the alignment of the symbol across the scanning beam. Truncation should be avoided unless absolutely necessary, for example, when printing on a highly curved surface, and then the maximum height should be printed.
