When it comes to USPS packaging, there is no one-size-fits-all answer. However, there are some general guidelines that can help you create an acceptable package.
When choosing a package shipping method, keep in mind the dimensions of the package and the dimensions of the mail carrier’s vehicle. For USPS, the dimensions of a package are:
Width: Not to exceed 18 inches
Height: Not to exceed 14 inches
Length: Not to exceed 24 inches
Weight: Not to exceed 45 pounds
Additionally, USPS requires that all packages be packaged in a way that will not obstruct the view of the mail carrier. This means that your package should be placed in a box or package that is at least as long as the height and width of the package, but not more than 3 inches wider or deeper.
When it comes to labeling your package, you should use the following guidelines:
All packages should be clearly and legibly marked with the sender’s name, address, and the package’s contents.
All packages should have a package identification number.
All packages should be packaged so that they will not require scissors or other sharp objects to open.
All packages should be packaged so that they will not require a saw to cut through them.
All packages should be packaged so that they will not require a hammer to break through them.
