When it comes to international shipping, one of the most common points of confusion is dimensional weight, sometimes called volumetric weight. At USA2Me, we want to help you understand how it works, why carriers use it, and how it can affect your shipping costs.
What Is Dimensional Weight?
Dimensional weight is a pricing technique used by shipping carriers to account for the amount of space a package takes up in relation to its actual weight.
In simple terms, if your package is large but light, you may be charged based on its size rather than its actual weight.
For example, a box filled with pillows doesn’t weigh much, but it takes up a lot of space on the airplane or truck. To make sure they’re charging fairly for the space used, carriers calculate the dimensional weight and compare it to the package’s real (scale) weight, then charge you based on whichever is higher.
How Is Dimensional Weight Calculated?
Each carrier (like FedEx, DHL, or USPS) has its own formula, but the concept is similar.
For most international shipments, dimensional weight is calculated using this formula:
Length × Width × Height ÷ Dimensional Factor = Dimensional Weight
The dimensional factor varies by carrier (usually around 139 or 166 for inches), but we’ll take care of the details for you when we process your shipment at USA2Me.

Why Carriers Use Dimensional Weight
Shipping companies have limited space in their vehicles and planes. By using dimensional weight, they make sure that a lightweight, bulky package doesn’t take up space that could have gone to a heavier, more compact item. This keeps shipping costs fair and consistent for everyone.
