Priority mail cubic meaning in shipping
In shipping, "cubic" refers to the volume of a package, measured in inches. In the context of Priority Mail, "cubic" refers to the cubic size of a package, which is used to determine the shipping cost.
The cubic size of a package is calculated by multiplying the length, width, and height of the package in inches. For example, if a package measures 12 inches long, 8 inches wide, and 6 inches high, its cubic size would be:
12 inches x 8 inches x 6 inches = 576 cubic inches
In Priority Mail, packages are categorized into different cubic size ranges, which affect the shipping cost. The cubic size ranges are:
- Small: Up to 1728 cubic inches (12 inches x 12 inches x 12 inches)
- Medium: 1729-3456 cubic inches (13 inches x 13 inches x 13 inches)
- Large: 3457-5184 cubic inches (14 inches x 14 inches x 14 inches)
- Extra Large: 5185-7776 cubic inches (15 inches x 15 inches x 15 inches)
- Extra Extra Large: 7777-10368 cubic inches (16 inches x 16 inches x 16 inches)
The cubic size of a package determines the shipping cost, with larger packages costing more to ship. The exact cost will depend on the weight and destination of the package, as well as the shipping service chosen.
It's worth noting that the cubic size of a package is different from its weight. A package can be heavy but still have a small cubic size, or it can be light but have a large cubic size. The cubic size is used to determine the shipping cost, while the weight is used to determine the handling and delivery of the package.
