Why? Because the aspect ratio (width:height ratio) of the two fonts are different./p>įor example, each character is X units wide but in font B each character is 2X wide. But bar code A may be 25% wider than bar code B because it was made using a different font. Two symbols may both be 1/2" tall because the text was formatted at 36 points. The Code 128 and Code 39 bar codes you make with C128Tools and C39Tools can vary in width even when the same chunk of text is formatted at the same point size. Font You Choose Determines the Width of the Barcode When you go from 24 points to 36 points the symbol will be 50% wider as well as 50% taller. More on that later.īefore we move on, let's all agree that formatting a piece of text at a larger point size increases the width as well as the height. In the case of C39Tools and C128Tools, the specific font you use determines the symbol's width. If you know how tall the space is you know at what point size to format the text. In some cases you have a space you're trying to fit a bar code into.
This is true across the Azalea product line with the exception of the Half fonts in UPCTools. Format it at 18 points and it will be 1/4" tall. There are 72 points per inch so if you format a string at 36 points the bar code will be 1/2 inch tall. When you format a string of text in an Azalea font, the bars will be as tall as the point size you specify. Barcode fonts impose a unique perspective on bar code geometry.įont Point Size Determines the Height of the Bars Text can be formatted at a wide range of point sizes. Text is inherently editable and malleable. Yes, images are usually hard to modify or change once created. Historically bar code geometry has been described in language that assumes bar codes of a fixed size that aren't easily changed. One can use either text or graphics to display and print a bar code On one level using fonts to make bar codes is no different than "painting" a JPG, TIF, or EPS file. Text formatted in a symbol font but text nevertheless, not a graphic image.
Azalea Software looks at a bar code and sees a chunk of text. When some people look at a bar code they see an image, a picture.
They take on new significance when dealing with scalable fonts like Azalea Software's barcode software product line. Symbol height and width, density (characters per inch, cpi), the nominal width, and aspect ratio are all interrelated variables. Several factors act in unison to determine a given barcode's physical characteristics.
