Dieline templates
Free box dieline templates
A dieline is the flat template of a box. It shows where the cardboard is cut and where it is creased, so artwork lands in the right place once the box is folded.
Our dieline generator draws the template to the exact size you enter, then lets you download it as an SVG file that opens in Adobe Illustrator, Inkscape and most other design software. Use it as a box template for your own artwork, or design directly on the box in your browser.

Box designer FAQs
Can't find your answer? We're happy to help with sizes, board and printing.
Is the online box designer free?
Yes. The box designer and the dieline templates are free to use, with no software to install. You only pay if you go ahead and order boxes from us.
What logo files can I upload?
PNG, JPG, SVG or WebP files up to 8 MB. An SVG or other vector logo prints sharp at any size. For PNG and JPG files, the designer shows the print resolution and warns you if the logo will look blurry.
Can I use my own design software instead?
Yes. Download the blank dieline template for your box size, add your artwork in your own software, and send the file to us with your quote request.
How do I get a price for my custom boxes?
Click "Request a quote" in the designer. We check your design and email you a price and a free PDF proof, usually within 1 business day. You can also request a custom packaging quote without using the designer.
Should I choose full colour or one colour printing?
Full colour is printed digitally and suits photos, gradients and shorter runs. One colour uses a single ink, which works well for a logo and handling marks on larger runs.
Is my box design saved?
Your design saves automatically in your browser, so it is still there when you come back on the same device. Download the print file if you want to keep a copy or share it.
Just need plain boxes?
We stock mailing boxes and shipping cartons in hundreds of sizes, ready to ship from Sydney and Melbourne — and most of our regular shipping cartons are Australian made.
