Key takeaways from this table
- 5000 cm³/kg is the global standard for express courier services. Most international shippers can use this number for back-of-envelope calculations.
- 6000 cm³/kg is the global standard for ground / postal services and works to the shipper's advantage (lower DIM weight than 5000).
- Australia Post at 4000 is the outlier. If you ship to or within Australia, expect higher DIM charges than most global carriers.
- USPS at 166 is unusually favorable in the US market — and the 1 cubic foot exemption rule makes it even better for small packages.
- FedEx and UPS at 139 are the most aggressive among major US carriers — they'll hit lightweight bulky packages hardest.
