X Dimension |
The X dimension refers to the width of the narrowest unit in a barcode, which is commonly referred to as a "module." Barcode elements are measured as multiples of the X dimension. Therefore, the X dimension correlates directly with the overall width of the barcode.
The X dimension also determines the density of a barcode, which specifies how many characters can be encoded per inch of barcode. When you decrease a barcode's X dimension, you increase its density, and vice versa.
The X dimension is measured in mils, where 1 mil equals 0.001 inch. For example, an X dimension of 7.5 mils is 0.0075 inches wide.
