Formula and assumptions
Dimensional weight = length × width × height ÷ carrier divisor, using the unit system the carrier specifies.
Carrier divisors and rating rules vary and can change; the carrier quote is authoritative.
Frequently asked questions
Is the divisor always 5000?
No. Use the value specified by your carrier/service.
Why exterior dimensions?
Carriers rate the packed parcel using their measurement rules.
Is the larger weight always billed?
Not necessarily; rounding and special fees may apply.
