You can define custom sizes for your posters and postcards.
To define a custom paper size:
The default templates shipped with Posterino use standard paper sizes named 'Poster', 'Letter' or 'Postcard'. You can change these paper sizes too.
For example, in general you would like a "Poster" to be 18" x 24" instead of the 20" x 30" Posterino sets as default. No problem, find the paper size named "Poster" and change the definition. The next time you create a poster it will be sized to 18" x 24".
