Label Size Settings
Australia Post MyPost Business service allows you to select from multiple label page formats for domestic orders. International MyPost Business labels are available in a single format only.
Change your label print settings
Go to Settings > Carriers.
Click the Edit (pencil) icon next to your MyPost Business carrier.
Select the Print Settings tab.
Choose your preferred label format.
Click Save.
All new labels created after saving will use your selected print settings.
⚠️ Important: Changing your label print settings does not update labels that have already been created.
If you need to print existing orders in a different label size, you'll need to create new labels.
Refund the original labels in your MyPost Business account, as MyPost labels are paid for and finalised when first created.
In SellerDash, select Actions > Reset Order for the affected orders.
Make any required changes, then create and print new labels.
Print labels using the new format
Return to the Dashboard, select the orders you want to process, then click Print Labels.
To print multiple labels at once, select all required orders before clicking Print Labels. SellerDash will generate a single PDF containing all selected labels, making batch printing quick and easy.
Label size options
Domestic labels
MyPost Business supports several label layouts for domestic shipments, both Parcel Post and Express Post have the same options available.
A6 – 1 label per page
This option is recommended if you're using a thermal shipping label printer, including:
Dymo 4XL or 5XL
Zebra printers
Brother thermal label printers
Any printer that supports standard 4 × 6 inch shipping labels
The label size is 105 mm × 148 mm (A6 / 4 × 6 inches).
A4 – 4 labels per page
Choose this option if you're printing onto A4 label sheets containing four A6 labels.
A4 – 1 label per page
This option is ideal if you're printing on plain A4 paper. Simply print the label and securely attach it to your parcel.
International labels
Unlike domestic labels, MyPost Business international labels are only available in A4 format. A6 thermal labels are not currently supported for international MyPost Business shipments.
Fixing label alignment issues
Label PDFs are generated directly by Australia Post and are produced at the correct dimensions.
If your labels aren't printing correctly:
Ensure your printer driver is up to date.
Confirm you've selected the correct paper size.
Set your PDF print scaling to 100% or Actual Size.
Do not use Fit to Page, Shrink to Fit, or similar scaling options.
If the label is only slightly misaligned, you can fine-tune the print position using the Top Offset and Left Offset settings in the Print Settings tab.
Note: Offset values should normally be no more than 1 or 2. If larger adjustments are required, it's usually a sign that your printer settings or PDF scaling are incorrect rather than an issue with the label itself.
