Enter the two smallest dimensions of the length, width, and height into the calculator to determine the girth of a package or parcel.

Girth Formula

The following formula is used to calculate the girth of a shipping parcel.

G = (D1 + D2) * 2

  • Where G is the girth
  • D1 is the smallest dimension of the package
  • D2 is the second smallest dimension of the package

The units for all 3 are typically expressed in inches, but they can be any units as long as they are consistent.

Girth Definition

What is girth?

Girth is a term used in shipping and receiving to describe 2 times the sum of the smallest dimensions of a package. For example, if the length and width are the smallest dimensions, they would be used in the calculation.

Example Problem

How to calculate girth?

  1. First, measure the length, width, and height of the package.

    For this example, these measured to be 20 inches, 10 inches, and 5 inches respectively.

  2. Next, choose the two smallest dimensions.

    In this case, the width and height are the smallest dimensions at 10 in and 5 in.

  3. Finally, calculate the girth.

    Using the formula above, the girth is calculated to be:
    G = (D1 + D2) * 2
    G = (10 + 5) * 2
    G = 30
