Freight Class Calculator
Density → NMFC-style class
Enter pallet or carton L×W×H and weight to get cubic feet, pounds per cubic foot (PCF), and an estimated LTL freight class.
Density class reference
| Min PCF | Estimated class |
|---|---|
| 50+ | 50 |
| 35 – <50 | 55 |
| 30 – <35 | 60 |
| 22.5 – <30 | 65 |
| 15 – <22.5 | 70 |
| 12 – <15 | 85 |
| 10 – <12 | 92.5 |
| 8 – <10 | 100 |
| 6 – <8 | 125 |
| 4 – <6 | 175 |
| 2 – <4 | 250 |
| 1 – <2 | 300 |
| <1 | 400 |
Some charts also list classes 77.5, 110, 150, 200, and 500 for specific commodities. Density alone never replaces an NMFC lookup.
FAQ
How is freight class calculated from density?
Measure the shipment (including pallet), convert to cubic feet, then divide total weight in pounds by cubic feet to get pounds per cubic foot (PCF). Map PCF to a density class chart — denser freight usually gets a lower class and lower rate.
What freight class is 10 PCF?
On common carrier density charts, about 10 PCF maps near class 92.5 (10 but less than 12 PCF). Confirm with your commodity’s NMFC item — some goods have fixed classes.
Do I include the pallet in dimensions?
Yes. Carriers cube the entire handling unit. Include pallet height in the height measurement and the pallet weight in the total weight.
Why did my carrier reclass my freight?
Reweigh/remeasure programs catch incorrect dims, weight, or NMFC codes. Density estimates can also differ from commodity-specific NMFC rules. Use this tool for planning, then verify codes on the BOL.
Is this an official NMFTA tool?
No. FreightKit is an independent density estimator. Official classification comes from NMFC rules and your carrier agreement.
