The GS1 General Specifications define the sizing dimensions of UPC/EAN barcode symbols. The sizing magnification range factors in both printing and scanning limitations. As a general rule of thumb, larger symbols are normally easier to read by a scanner. This UPC sizing chart is provided as a free resource from Bar Code Graphics.
Access to GTIN.cloud® enables members to completely manage their GTIN assignments, create high-resolution barcodes, and control their associated product data.
More importantly, an assigned personal GS1 Barcode consultant will not only assist with any and all questions but will validate information BEFORE publishing.
