1. What is Dimensional Weight?

Dimensional weight (also called volumetric weight) is a pricing technique used by shipping carriers like FedEx that takes into account package dimensions rather than just actual weight. It represents the density of a package.

2. How Does the Calculator Work?

The calculator uses the FedEx dimensional weight formula:

Where:

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

Explanation: The formula calculates how much space your package occupies in relation to its actual weight.

3. Importance of Dimensional Weight

Details: FedEx charges based on whichever is greater - the actual weight or the dimensional weight. Understanding this helps estimate shipping costs accurately.

4. Using the Calculator

Tips: Measure your package at its longest point on each side. Round each measurement to the nearest whole inch (FedEx's policy). Enter values in inches.

5. Frequently Asked Questions (FAQ)

Q1: What's the dimensional factor for international shipments?
A: For international shipments, FedEx uses a divisor of 139 for most services, but some services may use 166 - check with FedEx for specific services.

Q2: How do I measure package dimensions?
A: Measure the length, width, and height at the package's extreme points. Round up to the next whole inch (e.g., 5.25" becomes 6").

Q3: What if my package is irregularly shaped?
A: Measure from the furthest points of the package as if it were in a rectangular box.

Q4: Does FedEx always charge by dimensional weight?
A: FedEx charges based on whichever is greater - the actual weight or the dimensional weight.

Q5: Are there ways to reduce dimensional weight?
A: Use the smallest possible packaging that safely contains your item, and consider using more compact packaging materials.
