A poster is rarely viewed up close and with full attention. It usually works when passed in a hurry, from across the street or out of the corner of your eye - and it has literally a moment to stop the gaze. That is why a good poster is not dense with content. It is simple, strong and legible from a distance. Here is how to get there.
- One strong message works better than five at once - decide what should be remembered.
- Big, legible typography and a clear hierarchy guide the eye from the most important thing to the details.
- Contrast and a deliberate choice of colours decide whether the poster stands out in its surroundings.
- Check legibility from a distance - that is the natural range the poster will be seen from.
- Match format and paper to the display spot: one thing for a shop window, another for an outdoor wall.
One strong message
The biggest mistake on a poster is trying to say everything at once. The viewer has neither the time nor the wish to read paragraphs - in a few seconds they will take in one, at most two things. So decide what matters most and build the whole design around it.
If it is an event, put its name and date front and centre. If it is an offer, use a clear headline and what the viewer should do. Everything else - the details and the small print - drops to the background. A poster should spark interest and point further, not fit an entire leaflet's worth of text.
Hierarchy and big, legible typography
Since there is one message, it has to be visible at once. This is where typography comes in - on a poster, letters can and should be big. The key element, usually the headline or the name, has to dominate, with the rest of the information arranged beneath it by importance.
Build that hierarchy with size and weight of type, not with the number of typefaces. Two well-chosen fonts are plenty, and often one in a few variants is enough. Leave space around the text too - empty room is not a loss but a background that lets the main message truly ring out.
Shrink the design to the size of a postage stamp and look at it. If at that scale you can still see what it is about and what matters most, the hierarchy is good. If everything blurs into a blob, enlarge the main element and simplify the rest.
Contrast and colour
A poster competes for attention with its whole surroundings - other posters, shop windows, signs. To break through, it needs contrast. Dark text on a light background, or light on dark, reads effortlessly, and a strong colour pairing catches the eye from afar.
Colour is not only a way to stand out, though - it also carries mood. Warm colours energise and add drive, cool ones calm and build trust. It is worth matching the palette to the nature of the message and to the brand. We write more about how colours steer emotions in our post on the psychology of colour in advertising.
A poster that tries to shout everything at once ends up saying nothing - its strength comes from one clear voice.
Legibility from a distance
A design viewed on a monitor from half a metre away is a completely different setting from a poster on a wall seen from several metres. What looks subtle up close can be entirely unreadable from afar - small text disappears, gentle colour differences blend together.
So judge the design from a realistic distance. Step back from the screen, or print a thumbnail and look at it from across the room. The key information has to be legible from exactly the distance people will actually see the poster from.
Format and display spot
You match the poster's size to where it will hang. The largest formats in the calculator - SRA3 320 × 450 mm and the narrow 300 × 640 mm - work on walls and wherever the poster is seen from a greater distance. A4 and A3 suit shop windows, interiors and spots people walk close to. A format settled this way is the first choice when ordering posters, with the paper, the printed sides and the finish following right after.
Before you settle on a format, picture the specific place: how far away the viewer will be, whether the poster hangs alone or in a thicket of others, whether it is seen on the move or at leisure. The greater the distance and the more noise around, the more a bigger format and a simpler message pay off.
If you are unsure about the size, cut a rectangle in your chosen format out of a newspaper and hold it up in the target spot. You will see at once whether the poster dominates or gets lost - and adjust the format before sending the file to print.
Paper - matt or gloss
The choice of stock affects not only the look but also legibility in a given place. Glossy paper beautifully boosts colours and gives them depth, so it works well where saturation and effect matter. It has a downside, though: it can reflect light and create glare that makes the poster harder to read from certain angles.
Matt paper does not shine and reads evenly from every side, even under strong light. It suits shop windows and places where lamps or the sun light the poster. If you want intense colours, consider gloss; if you want calm legibility, go for matt. You will find more on choosing stock in our guide to materials and papers.
High-resolution photos
A large format ruthlessly exposes image quality. A photo that looks great on a phone screen can fall apart into pixels once blown up to poster size and, instead of attracting, start to repel. So even for an A3 or SRA3 poster, use high-resolution material.
The rule is simple: the bigger the poster, the bigger and better the quality of the photos and graphics used. It is better to drop a striking shot of poor quality than to print it blurry. How to prepare files so they print the way they look on screen is explained in our guide on preparing files for print.
From design to finished poster
A good poster is the sum of simple decisions: one message, strong typography, clear contrast, legibility from a distance and a format matched to the place. When these elements play together, the design stops the eye before anyone realises they are walking past it.
Once you have the design ready, just match the format and stock to the display spot and order posters in the right version. And if any doubts about size, paper or file preparation come up along the way, simply reach us through contact - we will help you choose the best solution.
