Freight density
Find your shipment density and estimated freight class.
Freight & shippingCompare gross and dimensional weight with a divisor that matches your carrier and service.
Compare gross and dimensional weight with a divisor that matches your carrier and service.
Whole-unit rounding per package. Carrier billing rules may differ.
The unrounded chargeable weight is the larger of actual and DIM weight. The rounded estimate rounds each package up to the next whole lb or kg. Enter the divisor in the displayed units; carrier dimension rounding, minimum charges, and contract rules vary.
Use this comparison before quoting a parcel whose packed size is large relative to its scale weight. It identifies which entered weight basis dominates under the selected divisor, not the final carrier price.
Confirm the divisor and dimensional rounding in the actual service agreement. A small change to an outside dimension can cross a billing-weight boundary. Do not substitute product dimensions for the sealed package, and keep minimum charges and surcharges outside this weight comparison.
Worked example: Freight Density vs. Dimensional Weight: Worked Examples
Use the divisor from your carrier quote or contract. The example uses 139 in³/lb or 5,000 cm³/kg; these are editable examples, not a rate guarantee.
A large, light package can consume more vehicle capacity than its physical weight suggests. Dimensional weight accounts for that space.
