1. What is Package Length + Girth?

The package length plus girth is a standard measurement used by shipping carriers to determine pricing and size restrictions. It combines the longest dimension of the package with the distance around its thickest part.

2. How Does the Calculator Work?

The calculator uses the standard formula:

Where:

• \( L \) — Length (longest dimension) in inches
• \( W \) — Width in inches
• \( H \) — Height in inches

Explanation: The girth is calculated by adding the width and height and multiplying by 2. This value is then added to the length to get the total package size.

3. Importance of Package Size Calculation

Details: Many shipping carriers have maximum size restrictions (typically around 108-165 inches total) and charge extra fees for oversized packages. Accurate measurement helps avoid unexpected costs.

4. Using the Calculator

Tips: Measure your package at its longest points for each dimension. Enter values in inches. All values must be greater than zero.
