At 297mm x 420mm (11.7 x 16.5 inches), A3 Posters hit the sweet spot between portability and impact: large enough to grab attention but compact enough for indoor spaces, noticeboards, menus, and retail displays.
Whether you’re a small business promoting an event, a café showcasing your latest menu, or a creative looking to bring your artwork to life, CMYK Printing provides professional A3 posters on premium silk stock with fast turnaround and UK-wide delivery.
Why Choose A3 Poster Printing?
Posters remain one of the most effective and affordable ways to deliver a message. Unlike digital ads that disappear in a scroll, printed posters have staying power and can capture attention in real-world spaces where your audience already is.
The A3 format in particular is popular because:
- Perfect size for indoor use – Not too small, not too large, easily readable from a short distance.
- Flexible applications – Ideal for promotions, signage, menus, retail offers, or event branding.
- Professional look – When printed on quality silk stock, A3 posters carry a smooth, premium finish.
- Cost-effective marketing – Affordable even for bulk orders, making them suitable for businesses and individuals alike.
If you’re searching for a professional, reliable way to produce impactful printed materials, A3 poster printing is a smart investment.
Premium Silk Paper for Professional Results
CMYK Printing offers two high-quality silk stock options to suit different needs:
- 150gsm Silk Stock – Lightweight and flexible, perfect for short-term promotions, event posters, and menus that may change frequently.
- 250gsm Silk Stock – Thicker and more durable, designed for displays or retail signage that need to maintain their sharp, premium look over time.
Every A3 poster is produced on high-resolution digital presses, ensuring crisp detail, vibrant colour, and a professional finish that helps your message stand out.
Understanding A3 Size and Bleed
For the best results, it’s important to understand how artwork should be supplied for A3 printing.
- Standard A3 size: 297mm x 420mm (11.7 x 16.5 inches)
- A3 with bleed: 303mm x 426mm (11.9 x 16.8 inches)
Adding a 3mm bleed on all sides ensures there are no white edges after trimming, giving your design a polished, edge-to-edge finish. CMYK Printing accepts high-resolution PDF or JPEG files, with fonts either embedded or outlined.
