Frequently asked questions
What is dimensional weight?
Dimensional weight is a pricing method that converts package volume into a shipping weight so carriers can charge for the space a parcel occupies.
Why do UPS, FedEx, USPS, and DHL differ?
Each carrier uses its own divisor and service rules, which changes the calculated billable weight for the same parcel.
How do I reduce dimensional charges?
Use the smallest practical carton, remove excess void fill, and compare billable weight against actual weight before shipping.
