Literature for a conference poster:design the background to land in three lines

Start with a shift in design philosophy.

In an oral presentation, the presenter can carry the background with their voice. A poster, though, is a medium where the paper fights alone. Readers scan the title, figures, and conclusion as they walk by, and skip long background text from the outset.

So rather than lamenting "I wrote it, but no one reads it," it's more rational to design the background so it's understood even without being read.

In the end, the background of a poster needs exactly three lines.

What we know. What we don't know. What this presentation adds.

One sentence per line — three sentences total. You might think "there's no way I can cut that much," but the truth is the reverse.

If you can't compress it into three lines, the problem isn't that your background is too long — it's a sign you haven't yet pinned down where your research sits.

Building these three lines rests on the same principle as the "similar studies, different studies, and blank space" sorting used when organizing literature for a conference talk.

Cap the citations on the poster at a small handful.

The selection criterion is whether a reference props up the three-line structure: a representative report to support line one, and the gap that defines line two. Keep only the minimum that plays those roles, and cut the rest ruthlessly.

The cut references don't disappear. They're held in reserve as your spoken answers when questions come during the session.

Splitting your literature into "references that go in print" and "references you bring up when asked" makes the cutting much easier.

The three-line structure works better as three visually distinct blocks than as running prose.

For example, stack three blocks vertically — "Known," "Unknown," "This study" — and connect them with an arrow. Even someone walking past can see, from the structure alone, "here's the gap, and here's the research that fills it."

Font size matters too. On a poster, text that can't be read from a distance may as well not exist. Shrinking the background text to cram in more information defeats the purpose.

You may be tempted to show a figure from a prior study in your background. That can work — with two cautions.

First, always verify any cited numbers and figures in the original paper's PDF. Check the axes, units, population, and outcome definitions. Once a number from an AI summary is printed on a poster, there's no reprinting it.

Second, reproducing someone else's figure verbatim requires clear attribution and respect for copyright. Rules vary by society and publisher, so when in doubt, it's safer to quote the numbers with a citation rather than reproduce the figure. Check your society's regulations as well.

The real test of a poster isn't the display — it's the conversations with the people who stop.

Since the printed background is down to three lines, prepare a 30-second spoken explanation to fill it out.

Something like: "This much was understood in this area, but this part hadn't been examined — and at our institution in particular, the situation is..." This is where the context that didn't fit in print gets its moment.

Minimal in print, generous out loud. That division of roles, I'd argue, is the heart of poster design.

Compressing to three lines doesn't happen in one sitting. It takes understanding each paper, sorting them, and then condensing.

In Paperfy, each collected paper's PDF and AI summary sit on the same page, which speeds up the first sorting pass. Because summaries are editable by hand, you can use them to draft and refine candidate poster sentences right inside each paper's summary.

The same workflow lets you correct misreadings on the spot. The day before the session, you can build a radio script from your three background lines and spoken supplement, and rehearse it by ear on the way there.

Summarizing literature for a poster isn't writing — it's cutting and sharpening.

Compress the background into three lines: known, unknown, what this study adds. Limit citations to the few that support those lines. Verify cited numbers and figures in the original PDF. Prepare a 30-second spoken version for the people who stop.

Start by condensing your current background draft into three lines.
