How the calculation works
Dimensional weight
Dimensional weight = length × width × height ÷ carrier divisor.
Billable comparison
The calculator displays the greater of entered actual weight and calculated dimensional weight.
How to use this calculator
- 1Choose metric or imperial measurements.
- 2Enter package length, width and height.
- 3Enter actual package weight.
- 4Enter the dimensional divisor required by the relevant carrier and service.
- 5Compare actual, dimensional and estimated billable weight.
Understanding the result
Large lightweight packages can have dimensional weight greater than their scale weight.
The divisor materially affects the result and should be obtained from the carrier for the specific service.
Important limitations
- Carrier formulas, divisors, rounding rules and oversize policies vary.
- This calculator does not quote shipping charges or guarantee the weight a carrier will bill.
- Use the current rules published by the relevant carrier.
Frequently asked questions
What is dimensional weight?
Dimensional weight is a shipping weight calculated from the amount of space a package occupies rather than only its scale weight.
Which dimensional divisor should I use?
Use the divisor specified by your carrier for the shipment, route and service.
Is dimensional weight always the billable weight?
Not necessarily. Carriers commonly compare dimensional and actual weight and apply their own billing and rounding rules.
