Large Format Poster Printing London – A Complete Guide to Sizes, Materials & Uses
Large Format Poster Printing London – A Complete Guide to Sizes, Materials & Uses
If you've ever stood in front of a bold A0 display in a London tube station, paused at a high-street shop window because of a striking A1 graphic, or picked up a flyer because the A3 poster beside it caught your eye — you already know the power of large format poster printing. It's one of the most effective, versatile, and cost-efficient forms of physical advertising available to London businesses today.
At DiGraphics, we've been producing premium quality large format poster printing in London for businesses of all sizes, across all sectors. From one-off urgent prints to bulk wholesale orders, from simple satin posters to specialist backlit and waterproof media — we do it all, and we do it well. This guide is designed to help you understand your options so you can make the right call for your next printing project.
What Is Large Format Poster Printing?
Large format poster printing refers to any print output that's significantly bigger than standard desktop printing — typically starting at A3 and going up to A0 and beyond. The term covers a huge range of materials, finishes, and end uses, from lightweight satin paper for indoor retail displays all the way through to heavy-duty waterproof vinyl for outdoor advertising in all weather conditions.
In a city as competitive as London, where businesses are fighting for attention on every street corner, large format printing is one of the most effective tools you have. Done well, a single well-placed A1 or A0 poster can generate more footfall, more inquiries, and more sales than a week of social media posts.
Poster Sizes Explained: A3, A2, A1, and A0
Understanding the difference between poster sizes helps enormously when you're planning a campaign or one-off display. Here's a practical breakdown:
A3 Poster Printing – 297 × 420mm
A3 is the smallest size in our large format range, but don't underestimate it. It's perfect for point-of-sale displays, menus, in-store promotions, and pinboard advertising. Compact enough to fit neatly almost anywhere, yet big enough to make a proper visual statement. Our A3 posters start from just £15.
A2 Poster Printing – 420 × 594mm
A2 is the all-rounder that works brilliantly across a huge range of applications. Double the size of A3, it offers considerably more visual presence while still being manageable and easy to frame or mount. Ideal for shop window displays, event promotions, and internal signage. Order A2 posters from £20.
A1 Poster Printing – 594 × 841mm
A1 is where large format printing really starts to command attention. At this size, your artwork fills a serious amount of wall or window space, making it the go-to choice for exhibitions, hoardings, retail window campaigns, and event display walls. A1 posters from £25 — exceptional value for the impact they deliver.
A0 Poster Printing – 841 × 1189mm
A0 is the big one. At nearly a metre wide and nearly 1.2 metres tall, an A0 poster is genuinely impossible to ignore. Used in exhibition halls, airport-style displays, large retail windows, and event backdrops, A0 printing is the choice when you need maximum impact and there's no room for compromise. A0 posters from £45.
Choosing the Right Material for Your Poster
Size is just the beginning. The material you choose has an enormous impact on how your poster looks, where it can be used, and how long it lasts. Here's a breakdown of the nine materials we offer at DiGraphics:
Satin Posters
The most popular choice for indoor poster printing in the UK. Satin has a subtle sheen that enhances colour depth and contrast without the glare of a full gloss finish. Brilliant for retail displays, event graphics, and exhibition walls. Available in A3, A2, A1, and A0.
Gloss Posters
When you want your colours to pop and your images to sing, gloss is the answer. The high-shine finish maximises vibrancy and makes photos look their absolute best. Perfect for fashion, food, and lifestyle advertising. Available in A3, A2, A1, and A0.
Matt Posters
For a refined, gallery-quality finish, matt is the professional's choice. No glare, no reflections, just clean, sophisticated print quality. Ideal for corporate environments, healthcare settings, and anywhere that demands a premium aesthetic. Available in A3, A2, A1, and A0.
Waterproof Posters
Our 440gsm waterproof poster media is designed for outdoor use or anywhere moisture could be an issue. It won't fade, smear, or deteriorate when exposed to rain, condensation, or humidity. Perfect for outdoor A-boards, market stalls, festivals, and anywhere the British weather might have something to say about it. Available in A3, A2, A1, and A0.
Self-Adhesive Vinyl Posters
Self-adhesive vinyl turns any smooth surface into a display area. Peel-and-stick application makes it incredibly easy to apply to shop windows, walls, vehicles, and display boards. It's repositionable, durable, and produces vibrant results. Available in A3, A2, A1, and A0.
Grey Back Blackout Posters
When you need a display that's fully opaque — for double-sided light boxes, window displays where you don't want the interior to show through, or any application requiring zero light penetration — grey back blackout is the specialist answer. Available in A3, A2, A1, and A0.
Backlit Posters
Designed specifically for illuminated lightbox displays, backlit poster film allows light to pass through evenly while delivering brilliant, vivid colour. The result is a glowing, eye-catching display that stands out even in a busy, brightly-lit environment. Available in A3, A2, A1, and A0.
PVC-Free Eco Posters
Increasingly important to businesses with sustainability commitments, our PVC-Free poster range delivers excellent print quality on an environmentally responsible 330gsm media. No PVC, no compromise on results. Available in A3, A2, A1, and A0.
