How this is calculated
Carriers charge for the heavier of actual weight and dimensional weight (length x width x height / divisor). This calculator shows which one wins and by how much — the difference can be tens of dollars per shipment.
- Dim weight = (L x W x H) / divisor
- UPS/FedEx domestic divisor = 139; international = 166 or 5000 cm³/kg
What to make of the number
Carriers often switch to dim weight at ~1 lb for anything over 12x9x6 inches.
Frequently asked questions
Does the divisor change for international?
Yes. International air freight commonly uses 166 (lbs/in³) or 5000 (cm³/kg).
