Freight class and density calculator
Determining the right freight class can save you both time and money. We’ve created an easy-to-use calculator to help you choose the right freight class and accurately plan your shipment.
Why do you need to know your freight’s density? Based on a shipment's dimensions and weight, density is one factor that influences freight classification. Typically, a shipment with lower density has a higher freight classification. Calculate your freight class here:

|Freight Density (in lbs per cubic foot)||Freight Class|
|Less than 1||400|
|1 but less than 2||300|
|2 but less than 4||250|
|4 but less than 6||175|
|6 but less than 8||125|
|8 but less than 10||100|
|10 but less than 12||92.5|
|12 but less than 15||85|
|15 but less than 22.5||70|
|22.5 but less than 30||65|
How to determine freight class.
Freight class is based on four factors.
1. Density: The space the items take up in the trailer and their weight factor into the density calculation.
2. Stowability: Items that are more difficult to store will be given a higher freight class. This includes shipments that might be hazardous or very heavy.
3. Handling: Any freight that requires special handling could be assigned a higher class.
4. Liability: Perishable freight or freight that could be easily damaged will be designated a higher freight class.
