What does the term "combined length + girth" refer to in postal services?

The term "combined length + girth" in postal services refers specifically to the dimension calculation used for pricing packages. This measurement is critical for determining the shipping costs associated with mailing items, as postal systems often base their rates on the size of the package rather than just its weight.

To understand this concept further, combined length and girth is calculated by adding the length of the package to the girth. The girth is defined as the distance around the thickest part of the package, which typically relates to its width and height. For instance, if a package measures 20 inches in length and has a girth of 30 inches, the combined measurement would be used to assess the appropriate postage needed, reflecting the space the package occupies in transit.

This measurement is essential for postal employees as it helps streamline the mailing process and ensures that packages are priced accurately according to their dimensions. Proper understanding of the combined length and girth enables both customers and postal professionals to engage with postal pricing structures effectively.
