Letter size and weight guidelines
We classify a letter as an item that:
- weighs less than 500g
- is no thicker than 20mm
- contains flexible items - nothing rigid or inflexible
- has a rectangular shape
- is no bigger than a B4 envelope (260mm x 360mm x 20mm).
If your item doesn't fit this criteria, we'd classify it as a parcel. View domestic parcel services.
Sending keys, pens, USBs or CDs?
Never put rigid or inflexible items in a regular paper envelope - even if you think they're small enough.
They could easily be damaged by our machines or torn from the envelope and lost.
Check our mailing boxes, bags and other packaging options to choose packaging to suit.

1 While we will endeavour to meet this timetable, the actual delivery speed will depend on where in each state/territory the item is being posted from/to, and the level of restrictions and congestion in our delivery network at the relevant time.
2 The national next business day delivery network operates between all capital cities (except Darwin and in Perth CBD only) and some major centres.
