Frequently Asked Questions
What is Dimensional Weight (DIM Weight) and how is it calculated?
Dimensional weight reflects package density and cargo volume. Freight and parcel couriers calculate DIM Weight as: (Length * Width * Height) / DIM Divisor. You are billed based on whichever is greater: actual scale weight or dimensional weight.
Which DIM divisors are used by FedEx, UPS, and DHL?
Standard commercial parcel carriers in the United States typically use a domestic divisor of 139 (or 166 for retail counters). International shipments generally use 139 for imperial inch calculations and 5,000 for metric centimeter calculations.
How can I minimize dimensional weight charges when packing parcels?
Use custom-cut boxes closely matched to item dimensions to eliminate empty interior space, avoid oversized packaging for lightweight goods, and compress soft goods with poly mailers or vacuum bagging.
