A3 Size and Bleed Requirements
A3 posters measure 297mm x 420mm (11.7 x 16.5 inches). Please supply your artwork with a 3mm bleed on all sides, giving a final file size of 303mm x 426mm (11.9 x 16.8 inches). Files should be supplied as high-resolution PDFs or JPEGs with fonts embedded or outlined.
Paper Stock Options
We offer two silk stock options. 150gsm silk is ideal for everyday use, posters that need to be lightweight, and short-term promotions. 250gsm silk is thicker and offers a more durable, premium feel — perfect for displays and signage that needs to look sharp for longer.
Every A3 poster is printed using high-resolution digital presses for consistent colour and professional finish.
