A3 Printing

A3 printing size is 297 mm by 420 mm (or 16.5 inches by 11.7 inches).  You can either print directly on and use this size (for example a poster or notice).  Alternatively, you can print on A3 and then fold it half to produce an A4 booklet.  You can discover the benefits of doing this in our page on A4 printing.

Let me ask you:

  • Do you want to promote your venue or sign your event prominently in a stylish manner?
  • Do you need to keep your employees or visitors informed about certain procedures and policies?
  • Do you want to display your design artwork or marketing portfolio to a prospects and clients?

If you have answered yes to any of the above, then A3 printing is the solution that you have been looking for.

You can choose from a range of finishes and paper weights.  The most common weights are 100, 120, 140, 160, 250 or 350 gsm (grams per square meter). 

The weight you choose depends on your needs.  For example, if you are looking to use your poster as temporary signage for an event then120-160 gsm is OK.  If you want to professionally show your artwork, then 250 might work better and if you are looking for permanent signage on policies and procedures then 350gsm is far more durable.

A3 Poster Printing


A3 posters are a great solution for promoting:

  • Events
  • Clubs
  • Restaurants
  • Shops

They give you more than enough room for a compelling headline, great photos and large printed address and contact details.  These posters are typically printed on 120, 140 or 160 gsm.

A3 Printing to Share Information


In many offices and workplaces, it is important that you share information on policies and procedures, especially those involving Health and Safety.  A sturdy A3 poster can contain a large amount of text along with plenty of diagrams or photos showing the process or procedure.

We recommend a paper weight of 250 or 350 gsm for these so they can be stuck directly to the wall.  They are more resilient and will look good for longer than the lighter paper stock.

You have a wide range of options.  Contact our friendly team today on 0207 613 7070 to see how we can help you win more business or communicate better with your staff using A3 printing.
