Dimensional Weight Formula:
| From: | To: |
Dimensional weight (also called DIM weight or 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. Shipping carriers use dimensional weight to calculate shipping costs based on package volume rather than actual weight.
The calculator uses the standard dimensional weight formula:
Where:
Explanation: The formula calculates the volume of the package and divides it by a standard factor (139 for inches) to determine the dimensional weight in pounds.
Details: Dimensional weight calculation is crucial for shipping companies to accurately price shipments based on the space a package occupies rather than just its actual weight. This ensures fair pricing for lightweight but bulky items.
Tips: Enter package dimensions in inches. All values must be valid positive numbers. The result will be displayed in pounds (lbs).
Q1: Why is dimensional weight used?
A: Carriers use dimensional weight to account for the space a package occupies in their vehicles, ensuring they're fairly compensated for shipping lightweight but bulky items.
Q2: What is the standard divisor for dimensional weight?
A: For measurements in inches, the standard divisor is 139. For centimeters, the divisor is typically 5000.
Q3: How do carriers charge for shipping?
A: Carriers charge based on whichever is greater: the actual weight or the dimensional weight of the package.
Q4: Are there different divisors for different carriers?
A: While 139 is standard, some carriers may use slightly different divisors. Always check with your specific carrier for their exact calculation method.
Q5: How can I reduce dimensional weight costs?
A: Use appropriately sized packaging, compress items when possible, and consider breaking large shipments into multiple smaller packages.
