Cubing is easy; just follow the 2 simple steps below:
1. Measure your parcel
The images below show you how to measure regular and irregular shaped parcels, and satchels.
Handy tip: when measuring the length and width of your parcel, always use the maximum points.
2. Cube your parcel
The cubic weight is the parcel's volume in cubic metres, multiplied by 250. To work this out, use the formula below:
Height x length x width x 250 = cubic weight
For example: 0.5m X 0.3m X 0.4m
= 0.06m x 250
= 15kg cubic weight
If the actual weight of your parcel is 10kg but the cubic weight is 15kg, we'll charge you the cubic weight because it is greater. But if the parcel's actual weight is 16kg, we'll charge you the actual weight because it is greater than the cubic weight of 15kg.
Please note: You do not need to cube Australia Post prepaid or flat rate satchels.
