Understanding Shipping Cube & Dimensional Weight
The Shipping Cube Calculator helps you determine the cubic volume of your package and its dimensional weight. These metrics are crucial for shipping, as carriers often charge based on whichever is greater: the actual weight of the package or its dimensional (DIM) weight.
Why is this important?
- Cost Calculation: Shipping costs are heavily influenced by the space a package occupies on a truck, plane, or ship. Larger, lighter packages can be more expensive to ship than smaller, heavier ones due to dimensional weight.
- Space Optimization: Knowing the cubic volume helps you optimize packaging, choose the right box size, and plan container loading efficiently.
- Avoiding Surcharges: Unexpected dimensional weight charges can significantly increase shipping costs. Calculating it beforehand helps you budget accurately.
How to Use This Calculator:
- Enter Dimensions: Input the Length, Width, and Height of your package. Ensure consistent units.
- Select Units: Choose whether your measurements are in Inches or Centimeters.
- Adjust Dimensional Weight Factor: The calculator provides a common default factor (e.g., 139 for inches/lbs, 5000 for cm/kg). However, this factor can vary by carrier (e.g., FedEx, UPS, USPS) and service type (ground, air). Always check with your specific carrier for their exact dimensional weight divisor.
- Calculate: Click the "Calculate Cube & Dimensional Weight" button.
What is Dimensional Weight?
Dimensional weight is a pricing technique used by freight and parcel carriers to charge for the amount of space a package occupies, rather than its actual weight. If a package is large but very light, its dimensional weight will likely be higher than its actual weight, and you'll be charged based on the dimensional weight.
The formula for dimensional weight is generally:
(Length × Width × Height) / Dimensional Factor
The dimensional factor (or divisor) is a number set by the carrier. For example, a common factor for US domestic shipments using inches is 139 or 166, resulting in a weight in pounds (lbs). For international shipments using centimeters, factors like 5000 or 6000 are common, resulting in a weight in kilograms (kg).
