Freight Density Calculator

Dimensional weight reflects package density, which is the amount of the space a package occupies in relation to its actual weight.


Freight Density Calculator

Freight density is one factor used to calculate freight class (the system created by the National Motor Freight Traffic Association (NMFTA) to standardize LTL freight pricing). Freight density is based on the shipment's overall dimensions and weight. Freight density can range from 50 to 1. A shipment with a lower density typically has a higher freight classification. You can use the tool below to determine your freight density and estimate your freight class.

Your Shipment Dimensions
Actual Weight

Density Estimated
Freight Class
Less than 1 400
1 but less than 2 300
2 but less than 4 250
4 but less than 6 150
6 but less than 8 125
8 but less than 10 100
10 but less than 12 92.5
12 but less than 15 85
Over 15 70

Note: This is an estimate only. If you need help determining the actual freight class for your shipment, use our Find Your Freight Class form or call a PartnerShip freight representative at 800-599.2902 for assistance.
