How to use the Shipping Dimensional Weight Calculator

Enter your carrier’s divisor and billing increment for the actual service. Dimensions are assumed to have already been measured or rounded according to that service’s rules.

The calculation

Dimensional kg = Lcm Wcm Hcm / divisor; billed kg = ceil[max(actual, dimensional)/increment] × increment

Worked example

50×40×30 cm at divisor 5,000 gives 12 kg dimensional weight; with 8 kg actual weight and 0.5 kg increments, billed weight is 12 kg.

Assumptions and limits

Does not fetch tariffs or verify carrier policies. Minimum charges, separate dimension rounding, oversize fees and multi-package aggregation are excluded.
