1. What is Dimensional Weight?

Dimensional weight (also called volumetric weight) is a pricing technique for commercial freight transport that uses an estimated weight based on package dimensions rather than actual weight. It reflects the density of a package (space it occupies relative to its actual weight).

2. How Does the Calculator Work?

The calculator uses the dimensional weight formula:

Where:

• \( Volume \) — Length × Width × Height of package (in cubic inches)
• \( Divisor \) — Standard dimensional factor (typically 166 for domestic shipments)

Explanation: Carriers use this calculation to account for lightweight packages that occupy significant space in their vehicles.

3. Importance of Dimensional Weight

Details: Shipping costs are based on whichever is greater - the actual weight or the dimensional weight. Understanding this helps optimize packaging and reduce shipping costs.

4. Using the Calculator

Tips: Enter package volume in cubic inches and the appropriate divisor (166 for most domestic shipments, 139 for international). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why do carriers use dimensional weight?
A: To account for lightweight packages that take up valuable space in trucks and planes, ensuring fair pricing based on space utilization.

Q2: What's the standard divisor value?
A: For domestic shipments in the US, it's typically 166 in³/lb. For international shipments, it's often 139 in³/lb.

Q3: How do I calculate package volume?
A: Measure length × width × height in inches. For irregular shapes, use the longest points in each dimension.

Q4: When is actual weight used instead?
A: When the actual weight exceeds the dimensional weight, carriers will charge based on the actual weight.

Q5: How can I reduce dimensional weight?
A: Use smaller boxes, compress contents when possible, and eliminate empty space in packages.
