Billable: 7

Billable weight: 7 lb (Dimensional weight billed).

  • Your DIM weight (7 lb) is 2 lb heavier than your actual weight (5 lb), so FedEx charges for the larger value.
  • To bring the DIM weight below your actual weight, reduce the package volume below 695 in³, or increase actual weight by adding denser product to the same box.
  • DIM weight = volume (960 in³) divided by 139, rounded up to 7 lb.

Next stepCompare carriers: UPS Retail and USPS use a DIM factor of 166 instead of 139, which may lower your billable weight by 6 vs 7 lb.
