Calculate package girth
Some parcel rules use length plus girth to decide whether a package is oversized. Enter the three box dimensions to calculate girth, length plus girth and package volume. It is useful for shipping checks, marketplace fulfillment, packaging design and rate planning.
Longest side as length
The calculator treats the longest dimension as the package length and wraps around the two smaller sides for girth.
