How do I make my barcode a specific size?

Barcodes don't quite work like this – essentially, you can't make barcodes an exact specific dimensional size.

Barcodes are sized based on the width of the narrowest bar, specified in millimeters. That sounds complicated, so we simplified it in Easy Barcode Creator: you specify the size of a barcode using the Factor option, as a percentage of that symbology's "default size". Play with it and you'll probably find a size that works well. 100% is the default and recommended size.

Can I just resize the barcode how I want once I export it?

Do not compromise the integrity of your barcode by modifying it after export. But if you must go against our recommendation, save the barcode as a vector EPS from Easy Barcode Creator, open it in Illustrator, and resize the barcode to a smaller size if you wish. However, this comes with two important notices:

• If you resize the barcode, you must make absolutely sure you do so proportionally. Do not make the barcode shorter or wider non-proportionally.
• You really shouldn't do this, and you run a serious risk that your barcode will not be scannable in the open market by forcing a smaller size. Do this entirely at your own risk.
