What is the MIL size (X dimension) of a bar code?

The X dimension is the width, in thouhs of an inch, of the narrowest element (bar or space) in a barcode. This is usually referred to in mil. So a .005" bar width would be referred to as a 5-mil label. The standard size for the 1D symbologies is 13 mil, these bar codes are used as reference in retail stores.
