Amazon FBA Label Printing Best Practices
When preparing inventory for Amazon FBA fulfillment centers, adhere strictly to Amazon's barcode quality specifications:
- Quiet Zone: Maintain at least 0.25 inches of blank white space around the barcode so scanners don't misread borders.
- Label Sizing: Standard Amazon FBA barcode labels are printed on 30-up sheets (1" x 2-5/8" on US Letter paper, such as Avery 5160).
- Print Quality: Always use vector SVG or 300 DPI PNG to avoid blurry or bleeding edges that cause carrier rejection fees.
