How Big Should My EAN-13 Barcode Be?
The official standard size for an EAN-13 barcode is 37.3×25.9mm – This can be officially reduced to 80% of the size (around 20x30mm) or increased to 200% the size. It is dependent on the retailer as to whether or not you can get away with a smaller or bigger size, however if you need verification reports then you should adhere to the standards as the barcode will not pass verification otherwise. It is always a good idea to do a test scan of your barcode before sending it to stores. Please see Barcode Dimensions for the official standards.
