PARCEL WEIGHT
Actual Weight vs Volumetric Weight
A practical explanation of why a light but large parcel can be charged differently from a compact parcel of the same actual weight.

Scenario: A Light Jacket in a Large Box
The packed jacket weighs 1.2 kg, but the box is much larger than the garment requires. A route that uses dimensional weight may treat the parcel as heavier because the box occupies more transport space.
Three Weight Terms
| Term | Meaning | Check |
|---|---|---|
| Actual weight | Mass measured on a scale | Warehouse parcel weight |
| Volumetric weight | Dimension-based carrier calculation | Length, width, height and current divisor |
| Chargeable weight | Weight used by the selected route | Current route rule |
Worked Comparison
Two parcels may both weigh 1.2 kg. The compact parcel can remain close to actual weight, while the oversized parcel may produce a higher volumetric figure. There is no universal divisor across every route, so use the current platform quotation rather than copying an old formula.
Common Mistakes
- Comparing routes before the final package dimensions are known.
- Using one carrier divisor for every shipping line.
- Keeping unnecessary boxes without checking the volume effect.
- Assuming consolidation always reduces chargeable weight.
