How to design an A3 print
Whether you’re creating A3 posters yourself or you’ve got a talented design team on hand to produce one for you, setting up your blank canvas is quick and easy. An A3 poster size is 297mm x 420mm, but don’t forget to leave at least a 3mm bleed area for when your A3 posters go through the printing and trimming process. This just ensures none of your important messaging or design is lost.
Before you get started, don’t forget to set your colour mode as CMYK and only use high resolution images (at least 300dpi), to ensure your A3 prints come out as high quality as possible. You’ll also need to embed or flatten your fonts.
