Method & assumptions
How Dimensional Weight Helper derives its result.
Formula
Dimensional weight = length × width × height ÷ carrier divisor, using the unit system the carrier specifies.
Recommended workflow
- Measure the packed parcel at the exterior points.
- Use the current divisor and unit system for the service.
- Check rounding, minimum weight, and oversize fees before purchasing a label.
Limitations
Carrier divisors and rating rules vary and can change; the carrier quote is authoritative.
For important work, verify assumptions against the authoritative source for your task.
