How to choose the right box size
Measure length, width and height of the item, or the item already wrapped. Our sizes are internal, so you can compare directly.
Leave a little space for bubble wrap, packaging paper or void fill so the item cannot move.
A smaller, lighter box usually costs less to send. Use our Box Finder or the AusPost satchel-fit ranges above.

Mailing box questions
What is the difference between a mailing box and a shipping carton?
A mailing box (diecut or tuck front) is a one-piece box that folds together without tape and looks great when opened, which makes it ideal for eCommerce orders. A shipping carton (regular slotted carton) has four flaps on the top and bottom that you close with tape. Cartons are usually larger and are best for bulky items, bulk orders, moving and storage.
Are the sizes internal or external?
The sizes we list are the internal dimensions in millimetres (length x width x height), so you can compare them directly with your product. Remember to allow a little extra room for protective packaging.
Which boxes fit inside AusPost prepaid satchels?
We group our boxes by the AusPost prepaid satchel they fit: small, medium, large and extra large. Putting a box inside the satchel gives your item more protection for the same postage.
Are your cardboard boxes recyclable?
Yes. Our mailing boxes and cartons are made from corrugated cardboard that can go in household paper and cardboard recycling. Brown kraft boxes are less processed, and our heavy duty double wall boxes are made in Australia.
Can I buy boxes in bulk or wholesale?
Yes. Most sizes come in several pack sizes, and our wholesale box deals offer full cartons and larger quantities at a lower price per box.
Can I get custom printed boxes?
Yes, we produce custom printed mailing boxes and cartons. Contact us with your size, quantity and artwork for a quote. You can also request free samples to check sizes first.
Can I pick up my order?
Yes, you can pick up from our warehouses in Minto NSW and Braeside VIC. We also offer free delivery to Sydney and Melbourne metro areas on orders over $500.
