How freight density is calculated
Shipment dimensions are converted from cubic inches to cubic feet, then total weight is divided by total cubic volume.
Why density matters
Dense freight generally occupies less trailer space for a given weight than low-density freight.
This tool provides a density-based estimate only. Actual LTL freight classification can depend on commodity characteristics, handling, stowability, liability and current carrier or classification rules. Confirm the final class with your carrier or freight professional.
Frequently asked questions
What is freight density?
Shipment weight in pounds divided by shipment volume in cubic feet.
Is freight class based only on density?
No. Density is important, but official classification can consider additional factors.
Should pallet dimensions include the freight?
Use the outside dimensions of the complete packaged shipment.
Using this calculator effectively
This tool calculates freight density and maps it to a simplified density-based class estimate. It is useful for early LTL planning, but an official freight class can depend on current classification rules and commodity characteristics beyond density.
Common uses
- Calculating pounds per cubic foot for a packaged shipment.
- Creating a preliminary LTL class estimate for comparison or quoting discussions.
- Seeing how package dimensions affect shipment density.
Tips for a better estimate
- Use the complete packaged outside dimensions and total shipment weight.
- Confirm the current NMFC or carrier classification for the actual commodity before tendering freight.
- Do not rely on density alone when handling, liability or stowability changes classification.
