Frequently Asked Questions
What is dimensional weight?
Dimensional (DIM) weight is a pricing method used by carriers to account for package size. It’s calculated by dividing package volume by a DIM factor. Carriers charge based on whichever is greater: actual weight or dimensional weight.
What are the DIM factors for different carriers?
FedEx and UPS use 139, USPS uses 166, and DHL uses 139 for domestic shipments. International shipments may use different factors. The factor represents cubic inches per pound.
How can I reduce dimensional weight charges?
Use smaller boxes, remove excess packaging, pack items tightly, and consider using custom-sized boxes for your products. Every inch matters when calculating DIM weight.
When did carriers start using DIM weight?
Major carriers began implementing DIM weight pricing for ground shipments around 2015. This encourages efficient packaging and compensates carriers for space used in trucks and planes.

Understanding DIM Weight Pricing
Carriers use dimensional weight to ensure fair pricing for shipments that take up significant space but weigh very little. By calculating both actual and dimensional weight, carriers charge based on the greater value. This encourages efficient packaging and helps carriers maximize vehicle capacity.
