Are there size requirements for shipping labels?
Generally, there are no specific size requirements for a pre-printed shipping label, but small packages tend to have smaller shipping labels, and larger packages need appropriately sized shipping labels. However, keep in mind that there are standard dimensions that most carriers expect a shipping label to have. If the label has a dimension larger than 7” x 4”, it is possible that some carriers, such as USPS, may not be able to read it.
