A1 Poster Printing: Big Enough to Notice, Easy Enough to Hang

Pixels you need for a sharp A1:

How Big Is A1, Really?

Numbers are one thing. Here’s how it looks in real life:

• Width: at 594 mm, A1 is almost exactly as wide as a standard 600 mm kitchen unit.

• Height: at 841 mm, it’s a little shorter than a kitchen worktop is high.

• Area: about half a square metre, which is eight sheets of A4 laid out in two rows of four.

• Next to a person: it reaches from about knee to waist height on most adults.

• In practice: it fits inside most A-board frames, shop-window posters and flip-chart stands.

A1, A0 or A2? Pick in 30 Seconds

Need something bigger or a different shape? See large poster printing or custom poster printing .

The viewing-distance rule: make your headline about 10 mm tall for every metre your reader will stand away. On an A1 poster, a 50 mm headline works from around 5 m. If you’re not sure which size you need, tell us where it’s hanging and how far away people will be.

Still unsure? Send a photo of the space and tell us when you need it. We’ll recommend one size, even if it’s the smaller, cheaper one.

Will My File Work at A1? A Plain-English Check

This is where most orders go wrong, and where we save you time.

1. Your A4, A3 or A2 design will scale up perfectly. All A-sizes share the same shape, so an A4 PDF scales to A1 with no distortion. Vector files (PDF, AI, EPS) stay sharp at any size.

2. Photos and JPGs need enough pixels. Use the table above. A modern 12-megapixel phone photo (about 4,000 × 3,000 pixels) prints well at A1, because 4,000 pixels on the short side of an A1 is roughly 170 dpi. That’s a good result.

3. Send the original, not a copy. Messaging apps and screenshots squash images.

4. Add 3 mm bleed if colour runs to the edge, and keep important text about 10 mm inside it.

5. Keep fonts safe. Send a PDF with fonts embedded or outlined.

6. Check your spelling out loud. Wrong dates and misspelt names are the most expensive mistakes on a poster.

No need to be an expert. Our free artwork check does all of this and tells you what to fix.

Where A1 Posters Work Hardest

• Shop windows and retail displays: a sale or new-range poster that’s seen from across the road. See our custom window graphics for graphics that fix to glass

• Pavement A-boards: offers, menus and events for passing trade

• Exhibitions and trade shows: stand panels and information posters

• Events and conferences: welcome posters, programmes and sponsor boards

• Restaurants, cafés and takeaways: menu and offers posters

• Offices, schools and clinics: notices, timetables and campaigns. See our directional and wayfinding signs

• Building sites and developers: information and safety posters

• Galleries, studios and photographers: art and photo prints

A1 posters work best as part of a set. Add a fascia sign above the door, and a roller banner for events.

How to Hang an A1 Poster

A great A1 can be spoiled by a bad fixing. Here’s what works:

• A1 frames and snap frames: buy one with an inner size of 594 × 841 mm. Check the inner size, not the outer.

• Poster hangers and rails: hang from the top edge so the weight is even and the poster doesn’t curl.

• A-boards: slide it in and check it sits flat behind the cover.

• Mounted on a board: a Foamex-mounted A1 stays flat and can stand or hang.

• Window fixings: use PVC and fix it inside the glass, or choose adhesive graphics for a permanent look.

• Adhesive tape or pads: quick for short runs on smooth walls. Test a small area first.

How It Works: Four Steps From Artwork to A1

1. Tell us what you need. The material, how many and the date you need them. A rough idea is fine.

2. Send your artwork. Upload a print-ready file, or send your logo, photo and wording and we’ll help shape it. PDF is best.

3. Approve your proof. We check your artwork for free, tell you straight away if the image isn’t big enough, and send a proof. Nothing prints until you say so.

4. We print and finish. Printed, trimmed and quality-checked in our factory. Collect from High Wycombe at the time we promised, or arrange delivery.

What Does A1 Poster Printing Cost?

People often search for cheap A1 poster printing, and fair enough: you want a clear number. Price depends on material (paper or PVC), finish, quantity, single or double-sided and how fast you need it. Larger quantities cost less per poster, so ordering a set for your whole shop or event usually saves money.

We don’t hide extras: send us your quantity and we’ll give you a clear A1 price with no obligation. If a simple paper poster will do the job, we’ll say so, and if A2 would work just as well, we’ll tell you that too.

Need it fast? We offer urgent printing on selected products. Tell us your deadline and we’ll tell you honestly whether we can make it in time.
