1. What is Dimensional Weight?

Dimensional weight (also called volumetric weight) is a pricing technique for commercial freight transport which uses an estimated weight calculated from the length, width and height of a package. FedEx uses this to account for the space a package occupies in relation to its actual weight.

2. How Does the Calculator Work?

The calculator uses the FedEx dimensional weight formula:

\[ \text{Dimensional Weight} = \frac{\text{Length} \times \text{Width} \times \text{Height}}{139} \]

Where:

Length — Longest dimension of the package (inches)
Width — Second longest dimension (inches)
Height — Shortest dimension (inches)
139 — Dimensional factor for FedEx (domestic shipments)

Explanation: The formula calculates how much space your package occupies in relation to its actual weight. FedEx will charge based on whichever is greater - the actual weight or dimensional weight.

3. Importance of Dimensional Weight

Details: Understanding dimensional weight helps you estimate shipping costs more accurately and potentially save money by optimizing your packaging.

4. Using the Calculator

Tips: Measure your package at its longest point in each dimension (length, width, height). Round each measurement to the nearest whole inch. Enter all values in inches.

5. Frequently Asked Questions (FAQ)

Q1: Why does FedEx use dimensional weight?
A: FedEx uses dimensional weight pricing to account for the space a package occupies in relation to its actual weight, as lightweight but bulky packages take up valuable space in trucks and planes.

Q2: Is the divisor always 139?
A: For domestic FedEx shipments within the U.S., the divisor is 139. For international shipments, FedEx uses a divisor of 139 for most services, but it's best to check current rates.

Q3: How do I measure package dimensions correctly?
A: Measure at the longest point of each side, rounding up to the nearest inch. For irregularly shaped packages, measure as if they were in a rectangular box.

Q4: What's the difference between actual weight and dimensional weight?
A: Actual weight is what the package weighs on a scale. Dimensional weight reflects how much space the package occupies. FedEx charges based on whichever is greater.

Q5: How can I reduce my dimensional weight?
A: Use smaller boxes when possible, compress contents if feasible, and avoid excessive packaging materials that add bulk without adding protection.
