A3 posters are a perfect solution for eye-catching promotions, artwork, menus, sale signs, notices, or event advertising. With custom A3 posters printing, you can make your message stand out in shop windows, schools, offices, staff rooms, community boards, or cafes. The A3 size gives you enough space for bold designs, large text, and clear images, but it’s still easy to handle, post, or frame. With Same day printing London, you can get your A3 posters printed and delivered fast—even for urgent, last-minute needs.
A3 posters are ideal for businesses, teachers, artists, event organisers, and anyone who wants to get noticed. Their handy size makes them easy to display just about anywhere.
You can design your A3 poster any way you want. We print in full colour for bright images and sharp, clear text. Choose from a range of paper stocks—silk, gloss, or matt for different finishes, or premium, heavier paper for a quality touch. Want to use your poster outside? Ask about waterproof or laminated options for extra durability.
A3 posters measure 297mm x 420mm, making them a great balance between visibility and convenience.
Send your poster design as a high-resolution PDF, AI, or PNG (at least 300dpi), using CMYK colours for the best print quality. Add a 3mm bleed if your design goes all the way to the edge. If you’re not sure about setup, our Same day printing London team can check your files and help you get your poster ready for print.
