What is the smallest barcode I can use for retail point of sale items?
A. Larger is always better for good print quality. We suggest 100% magnification, and increasing up to 200% or decreasing to 80% as print quality allows. Many factors influence the size of barcode symbols; the most important of which is the print quality achievable on the label, or packaging material. Some printing methods are not precise enough to produce quality symbols at smaller sizes. Because of this designers should discuss proposed symbol size with printers before making a decision on size.
