Dimensional Weight & Packaging
Length and Girth
Definition
A package-size measurement combining the longest side with the distance around the other two dimensions.
In practical terms
Length and girth is commonly used to evaluate whether a parcel fits a service size limit. Girth is generally twice the width plus twice the height, with the longest dimension treated as length.
Example
A long box is checked by adding its length to twice its width and twice its height.
