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 shipping cost, especially for lightweight but bulky items.

2. How Does the Calculator Work?

The calculator uses the dimensional weight formula:

Where:

• \( Length \) — Longest side of the package (inches)
• \( Width \) — Second longest side (inches)
• \( Height \) — Shortest side (inches)
• \( Divisor \) — Standard value determined by carrier (typically 139 for air, 166 for ground)

Explanation: The formula calculates the equivalent weight based on package volume rather than actual weight.

3. Importance of Dimensional Weight

Details: Carriers charge based on whichever is greater - the actual weight or dimensional weight. This prevents shipping lightweight but bulky items at unfairly low rates.

4. Using the Calculator

Tips: Measure package dimensions in inches, enter values, and select appropriate divisor based on carrier requirements. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why do carriers use dimensional weight?
A: To account for the space a package occupies in relation to its actual weight, ensuring fair pricing for all shipments.

Q2: What's the difference between 139 and 166 divisors?
A: 139 is typically used for air shipments while 166 is for ground shipments. The lower the divisor, the higher the dimensional weight.

Q3: How should I measure package dimensions?
A: Measure to the nearest inch, rounding up each dimension. Include any bulges or protrusions in your measurements.

Q4: When is dimensional weight used?
A: When the dimensional weight exceeds the actual weight of the package.

Q5: Can I reduce dimensional weight?
A: Yes, by using smaller packaging or compressing items where possible to reduce the overall volume.
