Some shippers restrict how big of a box you can ship, such as USPS with a maximum Combined Length plus Girth of 108 inches. To find out whether or not you exceeded that limit, follow these steps:
- Measure the three parcel dimensions in inches.
- Example: 30″ (Length) x 10″ (Width) x 15″ (Height)
- Add the measurements of the two smallest dimensions together and multiply by two. This is the girth of your package.
- Example: [10″ (Width) + 15″ (Height) ] x 2 = 50″ (Girth)
- Take the longest dimension and add this to the package girth. The result is the combined length and girth of your parcel.
- Example: 30″ (Length) + 50″ (Girth) = 80″ (Combined Length and Girth)
