Style (readable text, bar height, export size)
Bar height stretches bars vertically, which scanners ignore (only horizontal timing matters). The SVG download keeps the engine's exact geometry.

Usage
ISBN marks retail products for checkout scanners: print it on packaging or labels where GS1 checkout rules apply.
- ISBN on packaged goods for point-of-sale scanning
- ISBN on printed shelf labels with calm quiet zones
- ISBN proofs exported as SVG for packaging artwork
Shape
Pros
- ISBN scans on every retail checkout imager worldwide.
- Check digits are computed or verified before anything prints.
- SVG export stays sharp on packaging artwork at any size.
- Quiet-zone guidance is built into the preview and print SVG.
Cons
- ISBN needs precise widths — shrinking below ~80% magnification hurts scans.
- Curved cans and shrink-wrap glare distort the outer bars.
- Cropping the quiet zones is the most common print failure.
- Styling beyond black-on-white is not safe for checkout.
