# bar-ratio attribute

Type: | number
Inherited: | no
Used By: | barcode
Default: | 2.8
See: | bar-width

This attribute sets the width of the "thick bars" in a dual-width barcode like Code 39 or Interleaved 2 of 5. The thick bar will be set to bar-ratio * bar-width. For variable width codes like Code 128 or EAN-13, this has no effect.

Sets the width of the thick bars in the barcode to 2.2 points
