How many words on a research poster? 50 A0 boards counted

A finished A0 research poster carries about 650 words. Counted on 21 September 2026 across the 50 research poster examples on this site, the median board holds 662 words, the shortest 374 and the longest 1,028, and 49 of the 50 stay at 1,000 words or fewer. Results take the largest share, 20 percent of all the words, and 47 of the 50 have a methods block. These are this site’s own finished boards, a corpus that is still growing, not a sample of posters from conferences, but each one was written as a real study with numbers that reconcile.

How the words were counted

The 50 examples are A0 boards for fictional studies across health, the social sciences, the natural sciences and engineering: 30 portrait boards at 1656 by 2340 pixels and 20 landscape boards at 2340 by 1656. Each is stored as the finished HTML of the board. A script read every line of text on all 50.

Three rules decide what counts:

• Text inside charts is excluded. Axis labels, tick values and legend entries are drawn inside the chart and are not prose. Figure captions below the chart are counted.
• A word is any run of letters or figures, so “82.4%” and “1,980” each count as one word.
• Blocks are counted by kind, not by heading. A section block counts under its own role, a labelled protocol under methods, a numbered list under key points and the large sentence panel under key message. That is more reliable than reading headings, because a board can call its results block “What we found” or “Four reasons, in the renters words”.

The table below this article gives the result for each section.

Where the words go, section by section

Results are the biggest block on the board: present on 49 of the 50, with a median of 141 words and 20 percent of all the words counted. The one board without a results block is a comparison layout that puts its findings in the table instead.

Discussion comes second by share, on 47 boards at a median of 115 words, and methods third, also on 47, at a median of 98. Methods are short on purpose: most boards set them as labelled entries, design, participants, measure, analysis, rather than as a paragraph. The clinical trial poster sets its protocol as five labelled lines, design, participants, intervention, comparator and outcome, and adds a participant flow diagram beside it.

Introduction and abstract take 14 and 11 percent, and both are optional in practice. The introduction is missing from 8 boards and the abstract from 11; several of the boards without an abstract open straight into the research question or the headline finding instead.

Conclusions are brief, a median of 45 words on the 21 boards that carry a separate conclusion block, and references shorter still at 55, which is three or four citations. Six boards carry no references. The title band, meaning title, authors and affiliations, takes under 5 percent.

Three blocks are rare. Only four boards carry a future work section, at a median of 40 words, eight carry acknowledgements at 54, and fourteen carry a key message, one sentence set large in its own panel, at a median of 21 words. The key point list is common by contrast, on 44 boards at a median of 35 words, because it is the block a reader takes away from ten metres.

Portrait against landscape

Orientation barely changes the total. The 30 portrait boards have a median of 656 words, in a range of 453 to 1,028, and the 20 landscape boards 681, in a range of 374 to 830. The two shortest boards in the set are both landscape and the longest is portrait, so a portrait board tempts more writing at the extremes even though the middle is the same.

It changes the split. Landscape boards give 22 percent of their words to results against 18 percent on portrait boards. The extra width lets a landscape board run a wide results band with the chart beside it. Portrait boards spend slightly more on discussion and on conclusions, because their reading order is a column that ends at the bottom of the board.

Words against figures

Figures and words are not a simple trade. The 39 boards with one captioned figure have a median of 668 words and the nine with two are almost the same at 665. The two boards with more than two figures, the criminology cohort with four and the veterinary audit with three, drop to about 615.

The strongest effect is the size of the figure, not the number. Six boards are built around a single figure that takes more than a fifth of the board, and their median is 497 words, against 659 on the other 44. When one chart carries the finding, about 160 words come off the board.

The shortest boards

No board is under 370 words. The four shortest are all boards where a layout does the explaining:

• The education research poster, 374 words, a landscape board that compares two teaching approaches side by side and lets the comparison table do the work.
• The media studies poster, 400 words, which sets its method out as a five step chain rather than a paragraph.
• The climate science poster, 449 words, which gives most of its left panel to the finding set as one large sentence.
• The archaeology poster, 453 words, a timeline board where the dated sequence carries the argument.

At the other end, nine boards pass 800 words, and the longest, the soil science poster at 1,028, spends 210 words on results and 237 on discussion. It reads as a written report laid out on a board.

A word budget for your own poster

Published advice sits below these boards. SPIE’s poster guidelines warn that the least effective format is an enlarged copy of the manuscript, and the NC State guide by Hess, Tosney and Liegel says to use text minimally and big. NYU’s library guide suggests 300 to 800 words. Colin Purrington’s advice is 1,000 words or fewer, roughly 700 in the body and 300 in figure legends. The Better Poster layout described in the LSUHSC library guide keeps the sidebar of conventional sections under 500 words and puts the finding in large type in the middle. 41 of the 50 boards here are at 800 words or fewer, so treat 800 as a ceiling to write down from, not a target to fill.

A budget that matches the medians, for a 650 word A0 board:

Section	Words
Title band	30
Abstract, or skip it	0 to 90
Introduction	100
Methods, as labelled lines	100
Results, including captions	140
Discussion	115
Key points	35
References	55

If one chart carries the result, take 160 words off the introduction and discussion and let the figure fill the space. Whatever the count, set the body at a size that can be read standing up; research poster font size gives the sizes, and what a research poster is covers the blocks every board needs.

How to use this count

Write the sections first, count them against the budget, and cut before you lay anything out. The research poster templates page lists the 40 A0 layouts, including the hero figure layouts for a finding that is one chart. There is no poster specific tutorial yet; the closest steps are in making a flyer from a PDF or photo, which covers starting a design from a document you already have, such as your paper or abstract.
