1. What is Package Length Girth?

The package length plus girth is a standard measurement used by Australia Post and other postal services to determine shipping costs and size restrictions. It combines the longest dimension with the package's girth (circumference).

2. How Does the Calculator Work?

The calculator uses the Australia Post formula:

Where:

• \( L \) — Longest dimension (length) in centimeters
• \( W \) — Width in centimeters
• \( H \) — Height in centimeters

Explanation: The girth is calculated as twice the sum of width and height. The total package size is the sum of length and girth.

3. Importance for Australia Post

Details: Australia Post uses this calculation to determine if a package meets their size restrictions. Packages exceeding certain dimensions may incur additional fees or be ineligible for standard shipping.

4. Using the Calculator

Tips: Measure your package in centimeters at its longest, widest, and highest points. Enter these values to calculate the total size. All values must be positive numbers.
