Freight Class Calculator
Enter density in pounds per cubic foot to map it to a common freight class from 50 to 400. The final class can still be adjusted by material, packaging and the specific NMFC item.

--Density · lb/ft³

Example
| Item | Value | Unit |
|---|---|---|
| Density | 12.5 | lb/ft³ |
| Freight class | 92.5 | |
| Density | 12.5 | lb/ft³ |
Where people go wrong
- Treating the density band as the legal class while ignoring the specific NMFC item.
- Using dimensional weight instead of actual weight to compute density.
- Looking only at class while ignoring carrier pricing rules and accessorials.
FAQ
What class is a density of 12.5?
It falls in the 12 to 13.5 band, commonly class 92.5; confirm with the NMFC item and carrier.
Does a higher class cost more?
Usually yes, higher classes carry higher rates, but minimum charges, accessorials and lanes also affect the total.
