Volumetric weight calculates the density of a parcel based on its dimensions. It allows for more accurate shipping quotes across different carriers and modes.
Why is volumetric weight used?
To account for both the weight and amount of space a parcel occupies. Large but lightweight items can take up valuable cargo capacity.
How do you calculate it?
Measure dimensions, calculate cubic size, divide by the dimensional factor, and compare to actual weight. The greater amount is used for billing.
What are common dimensional factors?
FedEx and UPS parcel shipments use 139 cubic inches per pound. Air freight uses 166 cubic inches per pound. Ocean freight has the lowest factor.
Does size or weight matter more?
If an item is dense, actual weight will be used. But for large, lightweight items - like pillows - volumetric weight will be higher to account for space.
What are the 4 key calculation steps?
1. Measure dimensions in inches/cm 2. Calculate cubic size 3. Divide by dimensional factor 4. Compare to actual weight
How does this impact costs?
Accurately calculating volumetric weight ensures you are charged fairly by carriers for both parcel weight and size.
