1. What is FedEx Cubic Weight?

Definition: Dimensional weight (also called volumetric weight) is a pricing technique for commercial freight transport that uses the package volume to calculate the billable weight.

Purpose: FedEx and other carriers use this calculation to account for lightweight packages that occupy significant space in transport vehicles.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( L \) — Length of package (inches)
• \( W \) — Width of package (inches)
• \( H \) — Height of package (inches)
• \( \text{Dim Factor} \) — Dimensional factor (FedEx standard: 139)

Explanation: The actual weight and dimensional weight are compared, and the greater of the two is used to determine shipping costs.

3. Importance of Cubic Weight Calculation

Details: Understanding dimensional weight helps businesses optimize packaging to minimize shipping costs and avoid unexpected charges.

4. Using the Calculator

Tips: Enter package dimensions in inches and the dimensional factor (default 139 for FedEx). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why does FedEx use dimensional weight?
A: To account for the space a lightweight package occupies in relation to its actual weight.

Q2: What's the standard FedEx dimensional factor?
A: FedEx uses 139 for domestic shipments (in inches and pounds). International may differ.

Q3: How do I reduce dimensional weight costs?
A: Use smaller boxes, compress contents when possible, or consider multiple smaller packages.

Q4: What's the difference between actual and dimensional weight?
A: Actual weight is measured on a scale, while dimensional weight is calculated based on package size.

Q5: Do all carriers use the same dimensional factor?
A: No, UPS uses 139, USPS uses 166, and international factors may vary.
