Freight class calculator
Estimate LTL freight class from your shipment's density.
How it works
In US LTL freight, every shipment has a class from 50 (dense, cheap to move) to 500 (light and bulky). Density is the biggest factor: weight in pounds divided by volume in cubic feet, measured to the outside of the pallet including its height.
| Density (lb/cu ft) | Class |
|---|---|
| 50 or more | 50 |
| 15 to 22.5 | 70 |
| 10.5 to 12 | 92.5 |
| 8 to 9 | 110 |
| 6 to 7 | 150 |
| 4 to 5 | 200 |
| Under 1 | 500 |
This uses the traditional density guidelines. The NMFC classification system has been revised, and some commodities are classed on other factors, so confirm the class with your carrier or the NMFC before booking. Misclassified freight gets reclassed and rebilled.
Results are estimates based on typical industry values. Confirm final specifications with your supplier or carrier.
Frequently asked questions
How do I calculate freight density?
Measure the pallet's length, width and height in inches, multiply, divide by 1,728 for cubic feet, then divide total weight by cubic feet.
Does a lower freight class cost less?
Yes. Lower classes are denser and cheaper per pound to move.
