Parcel dimensions

How big? How small? How heavy?

The following guidelines will help you calculate the cost of your parcel and find out whether it can be sent using regular parcel delivery. For business contract customers, different size restrictions will apply - please contact your account manager for further details.

Maximum weight

The maximum allowed weight of a parcel lodged at an Australia Post retail outlet is 20kg.

Maximum size

Length - must not exceed 105cm.
Girth - parcel must not exceed 140cm.

Minimum size

Girth - must be at least 16cm. For example, a broom handle or a pencil-shaped parcel is not acceptable. If the parcel is box-shaped, both its length and width must be at least 15cm.

Cylinders

If your parcel is a long cylinder, its axis must not be more than 105cm (length) and its circumference (girth) must not exceed 140cm.

Boxes

If the parcel is box shaped, then its length (its longest dimension) must not exceed 105cm. The girth is measured around all the other dimensions and must not exceed 140cm. E.g. a parcel measuring 50cm long x 30cm high x 40cm wide has a girth of 140cm (i.e. 30 + 40 + 30 + 40 = 140).

Irregular shapes

To find out the length of an irregular shaped parcel measure between the two furthest points on the surface of the article. This length should not be more than 105cm.

To find out the girth of the item, measure around the widest part of the parcel at right angles to its length - this measurement should not exceed 140cm.

Cubic weight policy

Charges for parcels weighing more than 1kg that are square or rectangular in shape are assessed according to their actual weight or cubic weight equivalent, whichever is greater. The cubic weight is the parcel's volume in cubic metres multiplied by 250.

Australia Post reserves the right to apply cubic charges to a parcel weighing less than 1kg and to parcels that are irregular or cylindrical in shape.
