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. See which class your freight falls into:
Freight class reference chart.
| 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 |
| Over 30 | 60 |
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.
