Poster Printing: Which Size and Finish Do You Need?

The size and finish you need for a poster depends mainly on viewing distance and location, since a close-up A4 notice needs different sizing and finishing to an A1 display meant to be read from across a room, and the wrong choice can make even good artwork hard to read.

Why does viewing distance decide almost everything?

Viewing distance is the single biggest factor in choosing a poster's size, because text and imagery that read clearly up close can become illegible or ineffective from further away, and vice versa. A poster designed to be read within arm's reach, such as a notice on a door, needs a different layout to one designed to catch attention from across a shop floor or a large room. Before choosing a size, it helps to picture exactly where the poster will hang and how far away most people will be standing when they first notice it. It is also worth considering whether people will be moving past the poster or standing still in front of it, since a poster in a busy corridor or by a till point may only be glanced at for a second or two, while one mounted in a waiting area might be read at length. The first case rewards a bold headline and minimal supporting copy, while the second allows room for more detail, provided the most important information still leads.

Which size suits which situation?

Size	Typical use	Viewing distance
A4	Notices, small announcements	Close, arm's length
A3	Shop windows, noticeboards	A few metres
A2	Larger window or wall displays	Across a room
A1	Events, large retail displays	Across a hall or street

A4 sits at the smaller end of standard poster sizing and works well for close-range reading, while A1 needs bold, simple design because it is intended to be read from much further away. Between these extremes, A3 and A2 often do the most practical work for everyday business use, since they are large enough to be noticed from across a shop floor without needing the production time, handling care or wall space that A1 demands. Choosing between A3 and A2 for a shop window often comes down to how much competing visual clutter is nearby; a quieter window can work well with A3, while one already busy with other signage may need the extra size of A2 to stand out.

Does the finish change how a poster performs?

Finish affects both appearance and longevity. A laminated poster resists creasing, fingerprints and general wear, which suits anything expected to stay on display for weeks or months, or anything likely to be touched or handled. An unlaminated poster is quicker to produce and perfectly adequate for short-term notices that will be replaced within days. Choosing lamination for a poster that only needs to last a single afternoon adds cost and time without a meaningful benefit, so matching finish to expected display duration avoids unnecessary spend. Weather exposure should also be factored in separately from indoor handling, since a poster mounted outdoors, even briefly, faces different risks to one pinned up inside a sheltered office corridor.

How does artwork preparation change with size?

Artwork prepared for a small poster does not automatically scale well to a much larger one. Images need to be supplied at sufficient resolution for the final printed size, since anything stretched beyond its native quality will show visible pixelation, especially at A2 and A1. For handheld or close-range print, 300 DPI is the benchmark to work to, and this becomes even more important as size increases, since flaws that are invisible on a small notice become obvious on a large display viewed up close before someone steps back to read it properly.

What else affects the right choice?

Beyond size and finish, the environment the poster hangs in matters. A poster near a window is exposed to sunlight and should use fade-resistant inks and stock suited to that exposure. A poster in a busy corridor is more likely to be brushed against, making lamination worthwhile even for a shorter display period. Thinking through the physical environment, not just the message, leads to a poster that still looks good on the day it is taken down, not just the day it goes up. It is also sensible to think ahead to how the poster will be mounted, since some fixing methods suit certain stocks better than others, and getting this right avoids damage to the poster during the display period itself.

Choosing the right poster comes down to being honest about where it will hang, how far away people will be standing, and how long it needs to last, then letting size and finish follow from those answers.
