1. What is FedEx Volume Weight?

Definition: Volume weight (or dimensional weight) is a pricing technique used by FedEx and other carriers that considers package density rather than just actual weight.

Purpose: It ensures fair pricing when shipping lightweight but bulky items that take up significant space in transit vehicles.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Volume Weight — The calculated dimensional weight (pounds)
• Volume — Package volume in cubic inches (L × W × H)
• Factor — DIM divisor (139 for FedEx, may vary by service)

Explanation: The carrier will charge based on whichever is greater - the actual weight or the volume weight.

3. Importance of Volume Weight Calculation

Details: Proper calculation helps estimate shipping costs accurately and avoid unexpected charges. It also helps optimize packaging to reduce costs.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: How do I find package volume?
A: Measure length × width × height in inches. For irregular shapes, use the smallest rectangular box that would contain the item.

Q2: Does FedEx always use 139 as the factor?
A: The factor varies by service (e.g., 139 for domestic FedEx Express, 166 for FedEx Ground). Check current rates.

Q3: What if my package is heavy but small?
A: The carrier will charge by actual weight if it exceeds the volume weight.

Q4: How can I reduce volume weight charges?
A: Use more compact packaging, compress contents if possible, or consider freight shipping for very large items.

Q5: Do other carriers use volume weight?
A: Yes, UPS, USPS, and DHL all use similar dimensional weight calculations with different factors.
