What is the smallest box you can ship USPS?

Packages may not be smaller than 5″3.5′0.007′’ in physical dimensions. Packages may not be shorter than 6′3″x3′”x0.25′’ machinable packages are permitted, but they may not be any smaller than that. Package handling fees may apply to non-machinable packages. The combination length and girth (L+2W+2H) of your package may not exceed 108″ inches. If it does, you will need to use an alternative shipping service.

Any package that is smaller than the minimums specified by USPS is considered a “lettersize” piece and would be shipped as First-Class Mail. Lettersize pieces have a maximum size of 11.5″x6.125″ and cannot be more than 0.007″ thick. If the piece is larger than that or is not rectangular, then it would need to ship as a package and would incur package rates.

For packages (not letters), the minimum size the USPS will accept is 3″x5″x0.007″. Packages must be no larger than 108″ in combined length and girth.

There is no minimum size for First-Class Mail packages, but the maximum size for any package sent via First-Class Mail is 12″x15″x0.75″. Packages sent via First-Class Mail cannot weigh more than 13 ounces.
