1. What is Dimensional Weight?

Dimensional weight (also called volumetric weight) is a pricing technique for commercial freight transport that uses the package volume to calculate the billable weight. Carriers use whichever is greater - the actual weight or dimensional weight.

2. How Does the Calculator Work?

The calculator uses the dimensional weight formula:

Where:

• \( Length \) — Package length in inches
• \( Width \) — Package width in inches
• \( Height \) — Package height in inches
• \( Dim\ Factor \) — Dimensional factor (typically 139 for domestic shipments)

Explanation: The formula calculates the volumetric weight by considering how much space the package occupies relative to its actual weight.

3. Importance of Dimensional Weight

Details: Understanding dimensional weight helps businesses optimize packaging, reduce shipping costs, and accurately estimate freight charges before shipping.

4. Using the Calculator

Tips: Measure package dimensions accurately in inches. Common dim factors are 139 (domestic), 166 (international). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why do carriers use dimensional weight?
A: To account for lightweight but bulky packages that take up valuable cargo space.

Q2: What's the standard dim factor?
A: Most US carriers use 139 for domestic shipments, while international is typically 166.

Q3: How do I measure package dimensions?
A: Measure to the nearest inch at the longest points, rounding up fractions.

Q4: Can dimensional weight be lower than actual weight?
A: Yes, but carriers always charge based on whichever weight is greater.

Q5: How can I reduce dimensional weight charges?
A: Use smaller boxes, compress contents when possible, or combine multiple items into one shipment.
