Get Started with the Freight Density Calculator



To use the Density Calculator:

  1. Enter the dimensions of your shipment
  2. Enter the total weight of your shipment.
  3. Use line 1 for total shipment information or use multiple lines to list individual pallets.
Length (Inches) Width (Inches) Height (Inches) Weight (lbs)

Determining Freight Class

Freight density plays a major factor in choosing the right freight class. By calculating your freight density, you can more accurately plan your shipment, saving you time and money.

For an accurate estimate of your shipment’s freight class, start by entering your shipment’s dimensions and weight into the calculator, adding more lines as necessary. Contact our freight experts with any questions or inquiries you may have.

NOTES:
  • The freight class is mainly based on the density of the shipment.
  • More dense items such as steel and machinery have low classifications such as Class 50 through 85.
  • Fragile or bulky items fall into freight classes 125 to 500.

How do you calculate Freight Density?

The formula to determine the density of an item is: LxWxH / 1728 = Cubic Feet (CU FT), Weight (Pounds)/CU FT = Density (#PCF)
  1. Measure the shipment's dimensions: length, width, height.
  2. Multiply the measurements together (length x width x height).
  3. Divide the result by 1,728 (cubic inches per foot) to find the cubic feet of the shipment.
  4. Divide the weight by the total cubic feet. This result is the freight density, or pounds per cubic foot (#PCF).
Freight Density (in lbs per cubic foot) Freight Class
Less than 1 400
1 but less than 2 300
2 but less than 4 250
4 but less than 6 175
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
15 but less than 22.5 70
22.5 but less than 30 65
30 but less than 35 60
35 but less than 50 55
Over 50 50
