A3 Posters
A3 is the poster size for shop windows, event boards and the wall behind the till: big enough to read across a room, small enough to frame.

Artwork guidelines
Supply a PDF at 426 x 303 mm (the finished size plus 3 mm bleed). 150 dpi at full size is plenty for a poster; keep logos and text as vectors so they stay crisp. See our artwork guidelines.

How it works
Configure your posters, upload your artwork and the price updates as you go. Our configurator checks size, bleed and resolution when you upload, and a real person looks at every file before it goes to press.
