Freight Density FAQs

For more details, including how to calculate freight density or understand the relationship between density, freight class, and NMFC codes, check out our comprehensive FAQ section below. 

Density is a key factor in determining the freight class of a shipment and directly influences shipping costs. Shipments with a higher density typically have a lower freight class while shipments with a lower density are usually associated with a higher freight class. The freight class is one of the key components in determining the freight charges of a shipment. For LTL carriers, accurate density calculations are essential for optimizing space utilization and minimizing wasted capacity.

Use our density calculator tool to determine the density of your shipment and the corresponding freight class.  

Disclaimer: *The suggested freight class reflected in the Calculator is an estimate based only on density applied to the updated thirteen-tier density scale. Please refer to your product NMFC guidelines to verify the applicable freight class.
