How to Create an Academic Poster

A poster is read from a metre away by someone deciding within seconds whether to stop.

Academic posters are assessed on communication rather than completeness. The failure mode is universal and immediately visible: a poster containing a compressed version of the whole paper, in eleven-point type, that nobody can read from standing distance. Designing for the actual viewing situation is most of the task.

Understand the viewing situation

Viewers stand roughly a metre away, scan for a few seconds, and either engage or move on. They are often tired, in a crowded room, and choosing between many posters. Everything follows from that: large type, a clear focal point, and a message legible before any detail is read.

Write a title that does work

The title is the only thing read from a distance, and it determines whether anyone approaches. A descriptive title states the topic; a findings-led title states the result. The second is almost always stronger at a poster session.

Compare “An investigation into handover practices in acute wards” with “Structured handover reduced information loss by 40% across three acute wards”. The second tells a passer-by whether they care.

Cut the text ruthlessly

A common guideline is 300 to 800 words for an entire poster, and most first drafts contain two or three times that. Text should be reduced to claims and evidence, with the supporting detail carried by figures or left for the conversation.

• Use bullet points rather than paragraphs.
• Delete methodological detail unless it is the contribution.
• Replace description with a figure wherever possible.
• Keep the reference list to essential sources.

Follow a conventional structure, loosely

Most posters carry an introduction or background, methods, results, and conclusions, with the results given the most space. Where the guidance permits, weighting the layout toward findings rather than background serves the viewer better — background is what they can guess, findings are what they came for.

Design for legibility first

Type size is the most common failure. As a working guide, the title should be readable from several metres, headings from two, and body text from one. That usually means a title around 72 to 100 point, headings around 36 to 48, and body text no smaller than 24.

Use a clear typeface, avoid long lines, and leave generous white space. A crowded poster reads as anxious and is genuinely harder to scan.

Guide the eye deliberately

Viewers need to know where to start and where to go next. Columns read top to bottom then left to right; numbered sections remove ambiguity entirely. Whatever you choose, make it obvious — a layout requiring a decision about reading order loses people.

Give the poster one visual focal point, usually the key figure, positioned where the eye lands first.

Make figures do the explaining

A single well-designed chart often conveys the finding faster than any amount of text. Label axes clearly, put the message in the caption or the title, and simplify: remove gridlines, secondary series and anything that does not carry the point.

Check that colours remain distinguishable for viewers with colour vision deficiency, and never rely on colour alone to encode meaning.

Check the practical specifications

Confirm the required dimensions and orientation before designing, because rescaling afterwards distorts type and images. Design at full size in the software rather than scaling up a smaller document, use high-resolution images, and export as PDF for printing.

Allow time for printing. Posters are printed by services with queues, and last-minute printing is a common and entirely avoidable source of stress.

Prepare the conversation

The poster is a prompt for discussion, and at many sessions the discussion is what is assessed. Prepare a thirty-second summary and a two-minute version, and rehearse both. Anticipate the obvious questions — the limitation, the sample, what you would do next.

Standing beside your poster and letting people read in silence wastes the format. Offering “would you like me to walk you through it?” converts a passer-by into a conversation, which is the point of the exercise.

Design for accessibility

Posters are read by people with a range of vision, in variable lighting, sometimes at an angle. Strong contrast between text and background, sans-serif type at generous sizes, and no reliance on colour alone to carry meaning all improve legibility for everyone, not only for viewers with a visual impairment.

Avoid text over busy images, which is the most common readability failure, and check the poster at reduced size on screen — if it is illegible scaled down, it will be hard to scan in a crowded room.

Prepare a handout or a link

Viewers who want detail need somewhere to get it. A small handout with the abstract and your contact details, or a QR code linking to a fuller version, extends the poster beyond the session without cluttering it. Where you use a code, test it and make sure the destination works without a login.

Common mistakes to check before printing

Most poster problems are visible in a final review and expensive to fix afterwards, since printing is usually one-shot.

• Body text below 24 point, which cannot be read at standing distance.
• Paragraphs where bullets would serve, producing a wall of prose.
• Figures pasted at low resolution and pixelated at full size.
• No obvious starting point, leaving the viewer to guess the reading order.
• A conclusion that restates the aim rather than stating the finding.

View the file at 100% zoom before sending it to print. Designers routinely work zoomed out and are surprised by how small the type is at actual scale.
