Understanding Freight Density
What is freight density? Freight density is a measurement of how heavy a shipment is relative to its size, expressed in pounds per cubic foot (lbs/cu ft).
Why does it matter? Freight density is one of the key factors in determining freight class, which directly affects shipping rates. Higher density items (heavy for their size) typically qualify for lower freight classes and lower rates.
How is it calculated? Density = Weight ÷ Cubic Feet. First, calculate the cubic feet of your shipment (Length × Width × Height ÷ 1728), then divide the weight by the cubic feet.
Note: This calculator provides an estimate. Actual freight class may vary based on commodity type, handling requirements, and carrier-specific rules. Contact BRW for accurate shipping quotes.
