Good to know

These templates are set up for print with 3 mm bleed all the way round, so the finished file measures 303 × 426 mm, and with a 5 mm safe margin inside the edge. The editor shows the margin and bleed guides while you work. Change the text, colours and pictures in your browser, and let background colours and photos run all the way into the bleed. Use high-resolution images so they stay sharp on paper, and a headline that can be read from a few metres away. Download the design as PDF Print with crop marks, and the file is ready for the printer, or as a PNG for social media.
