Estimate what it will cost to ship a package based on its weight, dimensions, and shipping speed.
Carriers charge based on whichever is greater: the actual weight of a package, or its "dimensional weight" - a calculated weight based on how much space the box takes up. Large, lightweight boxes often cost more to ship than their scale weight suggests.
Dimensional Weight (lb) = (Length × Width × Height in inches) ÷ 139
Billed Weight = the greater of actual weight or dimensional weight
A 5 lb package measuring 12 × 10 × 8 inches has a dimensional weight of about 6.9 lb, so it's billed at 6.9 lb rather than 5 lb.
Is this an official carrier rate? No - this is a general estimate for planning purposes. Always confirm exact pricing with your chosen carrier.
It factors in package weight, dimensions, distance, and service speed against carrier rate structures.
A pricing method for large, lightweight packages based on volume rather than actual weight.
Each carrier has its own rate structure, surcharges, and dimensional weight policies.
