Freight Density Calculator

Calculate your shipment's density in pounds per cubic foot - the key input for determining freight class.

Shipment Details

Weight (lbs)

Length (in)

Width (in)

Height (in)

Enter weight and dimensions

Density is weight divided by volume. Convert dimensions to cubic feet, then divide the weight:

Cubic feet = (L × W × H) ÷ 1,728
Density = Weight ÷ Cubic feet

Once you have density, match it to a freight class - see Freight Class Explained, or use the Freight Class Calculator which does both.
