Get Unlimited AccessFollow these 4 simple steps to accurately determine billable package weight and eliminate expensive carrier surcharges.
Enter the length, width, and height of your outer box in inches. Always round up fractional values to the nearest whole inch.
Place your package on a scale and input the total scale weight in pounds (lbs), including all inner dunnage and packaging tape.
Use a carrier preset button: 139 for FedEx/UPS Air & DHL, or 166 for domestic US Ground shipping.
Compare actual weight versus dimensional weight. Carriers automatically charge whichever figure is higher as your final billable weight.
Eliminate dimensional surcharges and optimize multi-channel parcel logistics with our real-time volumetric calculation engine.
Instantly switch between FedEx, UPS, DHL Express, and Air Freight divisors with 1-click preset triggers.
Compare real scale weight against calculated dimensional weight automatically to identify over-packaged goods.

Dimensional weight reflects package density—the amount of space a parcel occupies in relation to its actual weight. Logistics carriers like FedEx, UPS, and DHL use DIM weight to prevent light, bulky boxes from consuming cargo capacity without paying appropriate freight fees.
DIM weight is computed using the formula: (Length × Width × Height) ÷ DIM Divisor. For example, a 16″ × 12″ × 10″ package equals 1,920 cubic inches. Divided by a standard 139 divisor, the dimensional weight comes out to 13.81 lbs.
Scale Weight is the physical weight of your package measured on a scale. Billable Weight is whichever value is greater between actual scale weight and dimensional weight. Major carriers always invoice based on billable weight.
Standard divisors vary by carrier and shipping service level:
Sellers can minimize volumetric penalties by using custom-fit boxes, switching to poly mailers or bubble envelopes for soft items, cutting down excess void fill, and consolidating multi-item orders into optimal master cartons.
Yes. CartHelperPro allows custom divisor overrides (including metric 5000 and 6000 kg/m³ air/ocean freight formulas) to accurately estimate billable weight across global logistics supply chains.
Carriers round up fractional package dimensions to the nearest whole inch before computing volumetric charges. Trim excess box space across your top-selling SKUs to shift shipments into lower freight brackets instantly.
