If you’ve ever shipped a package through Amazon FBA, Shopify, Etsy, USPS, UPS, FedEx, or DHL, chances are you’ve encountered the familiar 4″ × 6″ shipping label. Despite the availability of numerous label sizes, the 4×6 format has become the universal standard across the shipping and logistics industry.
