Label Size Settings
Australia Post MyPost Business service allows you to select from multiple label page formats for domestic orders. Only one option is provided for international orders.
If you're using a thermal shipping label printer such as a Dymo 4XL/5XL you would select the "A6 - 1 per page option".
To change label size settings, click on the CARRIERS tab in the app, then edit the MyPost Carrier settings (click the blue pencil icon)
Then click the PRINT SETTINGs tab
Domestic
If you are using label stationery that allows 4 x A6 labels to be printed per page you would select the "A4 - 4 per page" option.
If you are just printing on plain paper you would probably use the "A4 - 1 per page" option and then just tape the label to your parcel.
International
Like the options above, international labels can be set as well. Currently A4 is the only supported size for Auspost International labels.
Printer Adjustment
All PDFs are produced by the carrier systems, and are 100% the correct size.
If your labels aren't fitting your paper, ensure your printer drivers are up to date, ensure that your default printer settings are set correctly and that when printing you are not scaling the PDF when printing and choosing the correct paper size.
Some printers may require a minor adjustment if a part of the label prints off the edge of the label. This is very rare but you can adjust the position of the label in the PDF file generated by entering a value in the left or top offset fields.
If you find you need a value greater than 1 or 2 in these fields it suggests something is configured incorrectly in your printer settings. Try checking the scaling value used in your print settings. This should be set at 100% or "Actual Size" depending on the browser you're using.
