A1 Poster Size Design Principles
These poster dimensions are designed to provide information and visuals. The information must grab the attention of the reader. These are not like written documents that readers will go over in detail. Properly designed, the message will get across instantly.
The poster, regardless of the size, must have a story. There has to be a coherent structure (introduction to conclusion). One of the common pitfalls of poster design is cramming in too much data. Just get to the point since people are not likely to read them in detail.
Other Elements
Put graphs, images, diagrams and tables if needed. Boxes can be used to stress points. Of course you need to have the right tools. There are several computer graphics programs that can do the job. You can use illustrator and photo editing programs together. The A1 dimensions are widely recognized by printers, so the process will be straightforward.
Keeping the Target in Mind
The message and look of the poster must match its intended target. The poster may look good for you, but does it resonate with your intended audience? Whether you are aiming at schoolchildren or CEOs, you need to make sure the look is appropriate.
Balance
The key is balancing information presentation with artistic design. It’s vital that people like the poster’s appearance (that is what will grab their attention in the first place). But they must also get the information you are sending out. This takes time, which is why companies usually come up with several designs. Companies check for feedback before releasing the poster.
If you are going to make an A1 poster size, make sure that the information and design is sufficient for this type. Do not attempt to squeeze in more info than necessary. Aside from the text, you should also consider the colors, placement and other factors.
