Frequently asked
How is DIM weight calculated?
L × W × H (inches) ÷ divisor = DIM weight in pounds. Round up. Your bill uses max(actual weight, DIM weight).
Why did carriers shift to divisor 139?
In 2017 UPS and FedEx lowered divisors to 139 from 166. The change effectively raised shipping costs for light, oversized parcels — forcing shippers to right-size boxes.
Does international use the same divisor?
No — international shipments use IATA's volumetric weight (6,000 for cm³/kg) or carrier-specific divisors. Confirm with your international shipping portal.
