A media width detecting system is adapted to measure an absolute width of media without the need for human intervention or without the need for media to be referenced against a known location. The media width detecting system includes a measuring pattern that is provided across a media path for media. The measuring pattern can be in the form of, for example, a bar code pattern. The system further includes a reader that is provided relative to the measuring pattern so as to read the width of the measuring pattern. When media traverses the measuring pattern, a portion of the measuring pattern, for example, a subset of the bars of the bar code pattern, is covered by the media. The reader would then be adapted to determined a width of the measuring based on the covered portion of the media pattern in relation to the uncovered portion or uncovered bars.
