The A-series includes popular poster sizes such as A0, A1, A2, A3, and A4. Here’s a quick guide to each size, their dimensions, and suggested uses:

  • A0: The largest of the standard poster sizes, A0 is ideal for conference presentations, exhibition displays, and large-scale advertising campaigns. Due to its size, it has an excellent visibility range and can accommodate complex graphics and detailed information.

5 poster printing tips

While printing posters can be fairly easy, there are some things to consider to ensure the best results possible! Here are five top tips for poster printing

  1. Choose the right paper stock. The thickness of the paper determines the quality of your print, so make sure you select one that’s suited to what you’re looking for
  2. Include bleed and safe zone. Provide extra space (known as a bleed) when designing the margins of your poster to prevent crucial design elements from being cut off during printing. Additionally, include a ‘safe zone’ within the design free from key text or graphics to ensure they don’t get lost in the trimming process.
  3. Consider color. When it comes to color accuracy, it’s essential to use RGB (Red-Green-Blue) as opposed to CMYK (Cyan-Magenta-Yellow-Black) mode when setting up files for printing – this will ensure much more vibrant colors than if printed in CMYK mode.
  4. Select the proper resolution. Images displayed on computer monitors look sharp because they tend to have 72 dpi (dots per inch), while printers require 300 dpi at minimum for good results — otherwise, your image will look blurry or pixelated when printed out!
  5. Proofread & preview before sending. Before sending your file off for printing, double-check all spelling and details within your design and run a test print if possible — this way you can prevent any costly mistakes from slipping through!

Now that you know all about the different poster sizes and their ideal uses, it’s time to get creative and start designing your own!
