Standard size shipping boxes are pre-made cartons built to a fixed set of dimensions, rather than cut to fit one specific product. They’re the boxes you grab off the shelf when your item is a fairly common size and shape.
Most suppliers group these into a handful of tiers, from small mailers through to bulk cartons. Here’s exactly what counts as standard, with the dimensions for each tier and where to look if your item falls outside them. For the full picture on measuring, cubic weight, and choosing between them, see our shipping box sizes guide.
Here’s Everything You Need to Know in Under a Minute
- Standard shipping box sizes in Australia run from around 150 x 150mm small boxes up to 600 x 600mm large cartons, across five common tiers
- Match the tier to your product: small for jewellery and electronics, medium for shoes and appliances, large for bulky homewares
- Australia Post’s own parcel boxes range from 220 x 160 x 70mm up to a 500 x 440 x 350mm bulk option
- Domestic parcel limits still apply regardless of size: 105cm longest side, 140cm combined length and girth, 22kg max weight
- Flat or oversized items like TVs and artwork need dedicated box types rather than a standard size
- If nothing standard fits, custom cardboard boxes made to your exact measurements are the next step

Common Standard Box Sizes
Standard shipping box sizes in Australia typically run from around 150 x 150mm up to 600 x 600mm, across five common tiers:
- Small (around 150 x 150 x 100mm) — jewellery, candles, small electronics, or anything that fits a self-locking mailing box
- Small-Medium (around 300 x 215 x 150mm) — books, documents, skincare sets, small accessories
- Medium (around 330 x 250 x 200mm) — shoes, boxed appliances, mid-size retail orders
- Medium-Large (around 450 x 315 x 210mm) — apparel bundles, multi-item orders, retail kits
- Large (up to 600 x 600 x 600mm) — bulky homewares, larger appliances, heavy-duty freight
The Boxman’s own packing box range follows this same spread, from 150 x 150 x 110mm small boxes through to 600mm cube large boxes, all held in stock.
Local Carrier Guidelines (Australia Post)
If you’re sending through Australia Post, their own parcel boxes follow a similar spread. A Small measures 220 x 160 x 70mm, a Large is 390 x 280 x 140mm, and an Extra Large comes in at 440 x 277 x 168mm, with a bulk 500 x 440 x 350mm option for larger runs.
Whatever size you land on, Australia Post’s domestic limits still apply. Keep these in mind before you pack:
- Longest side: maximum 105cm
- Combined length and girth: maximum 140cm
- Maximum weight: 22kg
Check Australia Post’s parcel guidelines for their current limits, or read our full sizing guide for how cubic weight affects what you’ll actually pay.
When A Standard Size Doesn’t Fit
Not every product fits a standard tier. Flat or oversized items like screens and framed art use dedicated formats instead, such as TV boxes or art boxes, rather than a general-purpose carton.
If nothing standard works, custom cardboard boxes made to your exact measurements are the next step. For bulk-volume orders, importing can also work out more cost-effective, and we can help you source that too.

Frequently Asked Questions
What Size Boxes Does Australia Post Sell?
Australia Post sells parcel boxes in five sizes, from a Small at 220 x 160 x 70mm up to a bulk BX20 at 500 x 440 x 350mm, with a Large and Extra Large in between. These sit alongside their standard mailing boxes and satchels.
What Is The Standard Size Of A Packing Box In Australia?
There’s no single fixed standard. Australian suppliers typically group packing boxes into small, medium, and large tiers, sized around common product dimensions rather than one universal measurement. The Boxman’s own range runs from 150 x 150 x 110mm up to 600mm cube boxes.
What Size Is Australia Post Extra Large Box?
Australia Post’s Extra Large parcel box measures 440 x 277 x 168mm.
Are Box Sizes LxWxH?
Yes. Box dimensions are almost always listed as Length x Width x Height, in that order. Length is the longest side of the base, width is the shorter side, and height is how tall the box stands once assembled.
What Are The Standard Shipping Box Sizes In Centimetres?
Divide the millimetre figures above by 10 to get centimetres. A small 150 x 150 x 100mm box becomes 15 x 15 x 10cm, and a large 600mm cube becomes 60 x 60 x 60cm.
What Are D x W x H Dimensions?
D x W x H stands for Depth x Width x Height, another common way suppliers list measurements instead of L x W x H. Depth is the longest measurement, width is the side-to-side measurement, and height is how tall the box stands.
