A3 Posters

Posters are a great way to get a strong and impactful message out to the world

Local A3 Poster Printing Services Across Croydon and London

A3 poster printing fits nicely into most spaces, it's not too big, not too small. It's ideal for places where people are already close, like behind a counter, on a notice board, or in a shop window. You'll see A3 posters used for menus, offers, event details, or simple announcements. Many customers choose A3 because it's easy. It's quick to print, simple to frame, and doesn't feel over the top. You still get enough room to share the important information without needing to fill a whole wall.

At I You Print, we print A3 posters every single week for businesses and organisations across Croydon, London, and the wider UK. Some customers come in knowing exactly what they want. Others just know they need posters that look better than what they've been using. Both are fine. We deal with both all the time.

Let's walk through it properly, without overcomplicating things.

What's an A3 Poster, Really?

In simple terms, an A3 poster measures 297 × 420 mm. It's large enough to be noticed but still easy to handle, display, and store. That balance is exactly why A3 poster printing in Croydon is so popular with local businesses.

You'll often see A3 posters used for:

  • Shop window promotions
  • Event advertising
  • Community notices
  • Conferences and exhibitions
  • Internal office displays

That said, A3 isn't the only option, and we'll come to sizing in a moment.

Finished Sizes We Offer

Even if you're here for A3 posters, it helps to know what else is available. Sometimes a customer starts with A3 and then realises another size works better.

At I You Print, you can choose from:

  • A3 – compact, versatile, and easy to place
  • A2 – more impact, still manageable
  • A1 – bold and attention-grabbing
  • A0 – large-format displays
  • 20 in x 30 in – popular for retail and events

Most people printing A3 posters near Croydon stick with A3 for indoor use. For outdoor or long-distance viewing, they sometimes scale up.

We're happy to advise if you're unsure, and that conversation alone saves people money more often than you'd think.

Paper Stock Choices

Paper isn't just paper. The feel, weight, and finish all change how your poster comes across.

Here's a breakdown of the stocks we offer for A3 poster printing.

Lightweight Options

  • 90 gsm uncoated – Simple, economical, easy to pin or tape
  • 115 gsm silk – Slight sheen, colours look cleaner
  • 120 gsm uncoated – A bit sturdier, still natural

These are commonly used for short-term displays or internal notices.

Mid-Range Stocks

  • 150 gsm silk – One of the most popular choices
  • 170 gsm silk – Sharper print, more presence
  • 170 gsm uncoated – Textured feel, easy to write on

If you're ordering custom A3 posters for shop windows or events, this is usually the sweet spot.

Heavyweight Stocks

  • 250 gsm silk – Thick, professional, very durable
  • 250 gsm uncoated – Strong with a natural finish
  • 350 gsm silk – Rigid, premium, almost board-like

Here's why that matters: heavier posters don't curl, crease, or feel disposable. People treat them differently.

Single-Sided or Double-Sided Printing

Most A3 posters are single-sided, and that's absolutely fine. The poster conveys a single, clear message. One direction. No confusion.

That said, double-sided A3 poster printing does have its place. Think:

  • Window displays facing inside and out
  • Hanging posters
  • Notices visible from both sides

If you need it, we'll print it. If you don't, we won't push it.

Lamination Options

Lamination isn't about showing off. It's about protection and finish.

You can choose:

  • No lamination – clean and natural
  • Gloss lamination (single or double sided) – brighter colours, wipeable
  • Matt lamination (single or double sided) – softer look, less glare

For indoor A3 posters, many customers skip lamination.
For shop windows, outdoor use, or long-term displays, laminated A3 posters just last longer. Simple as that.

Sets: Ordering What You Actually Need

Not everyone wants thousands of posters.

At I You Print, we offer 1–30 sets, which works well for:

  • Multi-location businesses
  • Event packs
  • Campaigns with different versions

Each set can contain the same design or variations. Just tell us how you're planning to use them.

Quantity Options (From One-Offs to Bulk)

We print:

  • 1 to 25,000 A3 posters

Whether you're testing a design or rolling out a city-wide campaign, the process stays the same. The pricing just scales.

If you're looking for affordable A3 poster printing, bulk orders usually bring the cost per poster right down. We'll talk you through it without the hard sell.

Turnaround Times (Realistic and Honest)

We know deadlines matter. That's why we offer:

  • Same-day express
  • 1 working day
  • 3–4 working days

Same-day A3 poster printing is possible, but it depends on the spec and when the artwork arrives. Earlier is always better.

If something's tight, call us. We'll tell you straight what's doable.

Who Uses Our A3 Poster Printing?

Over the years, we've printed A3 posters for:

  • Local shops and cafes
  • Event organisers
  • Schools and colleges
  • Designers and agencies
  • Community groups
  • Corporate teams

Some need photo-quality A3 posters. Others just need something clear, quick, and affordable. Both matter.

FAQs

Can I order just one A3 poster?

In most cases, yes. As long as your artwork is ready and the paper is in stock, we can usually get it done the same day.
