Dimensional Weight in International Logistics: A Comprehensive Guide | BETTERluck Shipping
In the complex world of international shipping, understanding dimensional weight (also called volumetric weight) is critical to avoiding unexpected costs and optimizing your logistics budget. At BETTERluck Shipping (Guangzhou) Limited, we specialize in demystifying such complexities—offering the best services and prices for global cargo from China. Let’s break down everything you need to know about dimensional weight.
What is Dimensional Weight?
Dimensional weight is a calculation used by logistics providers to account for the space a package occupies in a transport vehicle (airplane, ship, truck) relative to its actual physical weight. It ensures that lightweight but bulky items (e.g., large boxes of pillows, furniture, or empty packaging) are priced fairly, as they consume valuable cargo space that could otherwise be used for heavier goods.
In short: Shipping costs are often determined by whichever is greater—actual weight (the scale weight of the item) or dimensional weight.
Why Do Logistics Companies Use Dimensional Weight?
Transport vehicles (planes, ships, trucks) have limited space. A shipment that’s light but takes up a lot of room (like a large box of foam) uses the same space as a heavier item (like machinery parts). Dimensional weight ensures carriers are compensated for the space they provide, making pricing more equitable for all shippers.
How to Calculate Dimensional Weight
The formula varies slightly by carrier and region, but it generally depends on the package’s length, width, and height. Here are the two most common standards:
1. Metric System (Used in Most Global Shipping)
For shipments measured in centimeters (cm) and priced in kilograms (kg):
Dimensional Weight (kg) = (Length × Width × Height) ÷ Dimensional Factor
The dimensional factor is typically 5000 for air freight and 6000 for sea freight (varies by carrier—always confirm with your provider).
Example: A box measuring 50cm × 40cm × 30cm
Volume = 50 × 40 × 30 = 60,000 cm³
Dimensional weight = 60,000 ÷ 5000 = 12 kg
If the box’s actual weight is 8kg, the shipment will be priced at 12kg (the higher of the two).
2. Imperial System (Common in U.S. and Some Markets)
For shipments measured in inches and priced in pounds (lbs):
Dimensional Weight (lbs) = (Length × Width × Height) ÷ Dimensional Factor
The factor here is often 139 for air freight.
Example: A box measuring 20in × 16in × 12in
Volume = 20 × 16 × 12 = 3,840 in³
Dimensional weight = 3,840 ÷ 139 ≈ 27.6 lbs (rounded up to 28 lbs)
Dimensional Weight vs. Actual Weight: What’s the Difference?
Carriers charge based on the “chargeable weight”—the higher of the two. For example:
