Why can a light parcel be billed at a heavier shipping weight?
KitForma editorial guide. Carriers may compare actual weight with a dimensional weight based on packaged length, width and height.
Step-by-step guidance
Carriers may compare actual weight with a dimensional weight based on packaged length, width and height. Enter the final outer measurements in https://kitforma.com/en/dimensional-weight/ and use the divisor specified for your carrier and service. A box that is unnecessarily large can increase this value even when the item is light. The calculation is an estimate: rounding, minimums, surcharges and local service rules still need checking with the carrier.
