    What is the quiet zone?

    Barcode standards require a “Quiet Zone” of around 6.5mm at each end of a barcode symbol. This Zone must be blank and the same colour (generally white) as the spaces in the barcode. This Zone is required so that the barcode decoder can tell where the barcode symbol starts and stops.

    An undersized quiet zone may render a barcode unreadable, or readable only in one direction.
