Research Poster Design: Scientific Poster Guide

A research poster (also called a conference poster or scientific poster) is a large-format, single-page visual summary of a study, designed to be displayed on a board and read by attendees walking through a conference poster session. It is not a shrunk-down manuscript. It has to communicate a study’s question, method, and finding to someone standing several feet away, deciding in a few seconds whether to stop, read, and start a conversation. That constraint — readability at a distance, under time pressure, in a room full of competing posters — drives every layout, structure, and typography decision covered below.

Research Poster vs. Conference Talk vs. Journal Paper

A poster is one of several formats a conference program uses to share the same underlying research, and each has a different job:

Poster. A static, self-contained visual document displayed for a session block (commonly one to a few hours), viewed one-on-one or in small groups, with the author standing beside it to answer questions. Best suited to work that benefits from an extended, informal conversation and from visual data display.
Oral talk / paper session. A scheduled, timed presentation (often 12-20 minutes plus questions) to a seated audience, with no one-on-one follow-up unless arranged afterward. Chosen by conference programme committees for work judged to merit a fuller, uninterrupted narrative.
Lightning talk. A very short (often around five minutes), tightly time-boxed slot in a back-to-back session — see CASRAI’s guide to writing and timing a lightning talk.
Three-Minute Thesis (3MT). A specific, judged competition format for a single slide and a three-minute spoken pitch of a thesis, distinct from a standard conference poster or talk — see CASRAI’s Three-Minute Thesis (3MT) guide.
Journal paper. The full, peer-reviewed written record of the study, typically produced and submitted after the poster or talk, not before it.

Which format a piece of work is assigned often isn’t the author’s choice — conference programme committees route submitted abstracts to a poster or oral session based on capacity, topic fit, and perceived significance, so a poster slot is not automatically a lesser outcome than a talk slot; the formats simply serve different audiences and interaction styles.

Standard Poster Sizes and Conference Specs

There is no single universal poster size — board dimensions are set by the individual conference or its venue, and vary enough that assuming a default without checking is one of the most common last-minute printing mistakes. Common formats in current use:

36 x 48 inches (landscape) — the most frequently used size at North American academic and biomedical conferences.
42 x 30 inches and other 3:4-ratio variants — also common, sometimes required for portrait-orientation boards.
A0 (84.1 x 118.9 cm), and occasionally A1 (59.4 x 84.1 cm) — the standard for most European and many international conferences, following ISO 216 paper proportions.

Orientation matters as much as raw dimensions: a landscape layout reads left-to-right in wide columns, while a portrait layout stacks sections top-to-bottom in a narrower, often single- or two-column format — the two require genuinely different section layouts, not just a rotated version of the same file. Always confirm the exact dimensions, orientation, and any file-format or margin requirements directly from the conference’s poster-presenter instructions rather than assuming a prior conference’s size still applies — a poster designed for the wrong board size either has to be reprinted or displayed shrunk or overhanging, both of which undercut legibility at exactly the distance the layout was designed around.

Structure and Sections of a Research Poster

Most research posters, regardless of layout philosophy (see the hierarchy section below), include some combination of the following elements. Not every section applies to every study or field — a methods-heavy engineering poster and a qualitative social-science poster will weight these differently — but this is the conventional inventory to work from:

Title. States the finding or question, not just the topic, in language a non-specialist attendee can parse at a glance.
Authors and affiliations. Full author list in byline order, each linked to their institutional affiliation, generally directly beneath the title. See CASRAI’s author affiliation entry and guide to formatting the corresponding-author line for symbol and formatting conventions.
Background / introduction. The gap or question motivating the study, kept short — a paragraph or a few bullet points, not a literature review.
Methods. Enough detail for a knowledgeable reader to judge the study’s rigor, generally summarized rather than fully specified (full protocol detail belongs in the linked manuscript, not the poster itself).
Results. The core of the poster — usually led by figures, charts, or tables rather than prose, since visual data display is what a poster does better than a talk or a paper.
Conclusions. The one or two takeaway statements a visitor should remember, stated plainly.
References. A short, selective list, generally in small type at the bottom or in a corner — not a full bibliography.
Acknowledgements. Non-author contributors, technical or writing support, and collaborators who don’t meet authorship criteria — see CASRAI’s acknowledgments section entry and acknowledgments vs. authorship comparison for who belongs in which list.
Funding statement. See the research-administration section below — funder acknowledgement is generally a grant-agreement obligation, not optional courtesy text.
QR code and contact information. Covered in its own section below.

Field and conference norms vary on ordering and whether background/methods/results/conclusions run as an IMRaD-style sequence or are compressed around a single headline finding — that choice is the traditional-grid-versus-Better-Poster decision covered next.

Visual Hierarchy, Layout, and How Much Text Is Too Much

Two layout philosophies dominate current practice, and which one fits depends on your field’s norms and your conference’s expectations — check what posters at your target venue typically look like before committing to either.

The traditional grid. Sections run left to right (or top to bottom in a portrait layout) following IMRaD order — Introduction, Methods, Results, Discussion/Conclusion — typically in two to four columns, with the title spanning the top and author/affiliation/funding information directly beneath it. This remains the dominant format at most biomedical, life-science, and engineering conferences, and reviewers and session chairs generally expect to be able to find each section in a predictable place. Within this format, the core design discipline is still hierarchy: the single most important sentence (the takeaway finding) should be the largest, boldest text block on the page, not buried in a Results paragraph at reading-distance font size.

The “Better Poster” alternative. Beginning around 2019, a template popularized by Mike Morrison (then a Ph.D. candidate at Michigan State University) proposed inverting that logic: a large central panel states the single main finding in plain language and oversized type, with a QR code linking to a full-detail version, and the traditional sections reduced to a narrow supporting column. The explicit goal is to let a passerby absorb the one-sentence takeaway without reading anything else, then opt in to the full methods/results only if it’s relevant to them. It has been widely discussed and adopted in several fields, though it is a genuine departure from a still-dominant convention rather than a settled replacement for it — some review committees and mentors still expect the traditional grid, so this is a decision to make deliberately, not by default.

Whichever format you use, the same underlying hierarchy principles apply: establish a clear visual path (most eye-tracking guidance points to a left-to-right, top-to-bottom or Z-pattern scan), use size and weight — not color alone — to signal importance, and leave generous white space rather than filling every available inch. On text volume specifically: if a section requires full sentences to explain, it is almost always too dense for a poster read at a walking pace — converting prose to short bullet points, and moving anything a reader would need to sit down and study into the linked manuscript or preprint instead, is the standard fix. A poster that can be understood from about ten feet away in ten seconds, and read in detail from about three feet away in a few minutes, is doing its job on both levels.

Software: PowerPoint, Illustrator, BioRender, and Alternatives

Microsoft PowerPoint is by far the most widely used tool for poster design, mainly because it is already familiar and because a poster can be built as a single custom-sized slide. Its main risk is resolution: images pasted in at screen resolution look fine on a monitor but pixelate badly once printed at 36-48 inches wide, so every embedded image needs to be checked at its final printed size, not its on-screen size (see the printing guidance below).

Adobe Illustrator is a vector-based alternative preferred by designers and labs producing posters routinely. Because vector text, lines, and simple graphics scale to any size without quality loss, Illustrator avoids the pixelation problem PowerPoint is prone to, and gives finer control over typography, alignment, and print-ready color (CMYK) output. The tradeoff is a steeper learning curve for researchers without prior design-software experience.

BioRender is used specifically for scientific and biomedical illustrations — pathway diagrams, mechanism figures, experimental-design schematics — built from a library of pre-drawn icons, and is commonly combined with PowerPoint or Illustrator rather than used to build the whole poster layout on its own. Because BioRender content is licensed rather than owned outright, check the current terms for the license tier in use (individual vs. lab/institutional) before publishing or printing a poster that includes BioRender figures, since permitted use and attribution requirements differ by plan.

Other tools seen in practice include Canva (template-driven, easiest entry point but least print-precision control) and LaTeX poster classes such as beamerposter or tikzposter (common in mathematics, physics, and computer science, where consistent typesetting of equations matters more than graphic design flexibility).

Typography, Color, and Legibility at a Distance

Because a poster is read at a range of distances by design, type sizes need to be set for the farthest and nearest reading contexts, not a single comfortable size:

Title — large enough to read from roughly 15-20 feet away (commonly 85-120pt, though this depends on board size and typeface).
Section headings — readable from about 6-8 feet (commonly 36-44pt).
Body text — readable from about 3-4 feet, where most engaged readers will actually stand (commonly 24-32pt; anything meaningfully smaller forces readers to lean in, which most won’t do).

Use a colorblind-safe palette (avoid relying on red/green distinctions alone to separate data series or highlight results) and keep contrast high between text and background. Limit body text to short paragraphs or bullet points rather than dense blocks — the goal is scannability, not manuscript-style prose.

QR Codes and Contact Information

It is now common practice to include one or more QR codes on a poster linking to supplementary material the physical poster can’t hold, most often:

A preprint version of the full manuscript (e.g., posted to bioRxiv or medRxiv), for readers who want the complete methods and results.
The underlying dataset or code repository, ideally via a persistent identifier (a DOI-bearing repository record) rather than a link that may move or expire.
A PDF or slide-deck version of the poster itself, or a short recorded summary, for attendees who want to review it after the conference ends.
The presenter’s ORCID iD or lab website, for follow-up contact.

Practical conventions worth following: place the QR code in a consistent, expected location (commonly a bottom corner, near the title, or — in Better Poster-style layouts — directly beside the main-finding panel), size it large enough to scan from close range without a caption explaining what it links to being necessary, and test it with an actual phone camera before printing, since a QR code generated at low resolution or shrunk too far can fail to scan even though it looks fine on screen. Label what the code links to in a short caption (e.g., “Scan for preprint + dataset”) rather than leaving it unexplained. Alongside the QR code, list a direct contact — email or ORCID — in plain text for attendees who photograph the poster rather than scan it on the spot.

Preparing Files for Printing and Getting a Poster to the Venue

Most poster printers (university print shops, conference-affiliated vendors, or commercial large-format printers) expect a print-ready PDF at final size, not a PowerPoint or Illustrator native file. Two things cause most last-minute printing problems:

Image resolution at final size, not screen size. An image that looks sharp at a 4-inch width on a laptop screen can be far below print resolution once it’s the 12-18 inches wide it needs to be on a 36x48in poster — check each image’s effective DPI at its final printed dimensions, not its resolution as originally saved. The DPI, format, and resolution conventions used for journal-submission figures are a useful reference point for the same underlying math (see CASRAI’s guide to scientific figure rules for journal submission), though poster printing generally tolerates a lower effective DPI than a journal’s print requirements because posters are viewed from further away.
Color mode. Design software often defaults to RGB (for screens); most large-format printers expect CMYK, and colors can shift noticeably in the conversion — confirm which color mode your printer expects before finalizing.

Build in time for at least one proof or test print if the venue and budget allow it. For transport, a rolled poster in a rigid mailing tube is the standard method for checked or carry-on air travel — check the airline’s carry-on size allowance before relying on it, since an oversized tube may need to be checked or gate-checked. Fabric (fold-and-iron) posters are a growing alternative specifically because they pack into a small bag and travel without a tube, at a modest cost and print-quality tradeoff versus paper or vinyl. Whichever method you use, always carry a digital backup (PDF on a drive, or cloud-accessible) when traveling to a conference in case a physical poster is damaged, delayed, or lost in transit and needs an emergency local reprint — many conference venues and nearby print shops can turn around a same-day or next-day reprint from a PDF if given enough lead time.

How to Present at a Poster Session

Designing the poster is only half the work — presenting it well during the session is what turns a well-laid-out board into an actual scholarly conversation.

Prepare a 30-second pitch. Most poster-session visitors decide whether to engage within seconds, and most conversations start with some version of “can you tell me about your poster?” A short, rehearsed opening — the question, the core method in one sentence, and the headline finding — gives every visitor a clear entry point regardless of how much background they arrive with. Have a slightly longer (roughly two-minute) version ready for visitors who want more detail, without defaulting to reading the poster’s text aloud.
Read the visitor before deciding how much detail to give. A specialist in your subfield may want to skip straight to methods and results; a generalist or student may want the plain-language takeaway first. Watching for cues (what they’re looking at, what they ask first) and adjusting depth accordingly matters more than delivering a fixed script every time.
Handling questions. Expect questions about methodological choices, limitations, and what you’d do differently or next — these are normal, not adversarial, and a poster session’s back-and-forth format is specifically what makes it useful for getting that kind of feedback before a study is finalized for journal submission. It is fine to say a question is outside the current study’s scope or that you don’t yet have that data, rather than overstating what the work shows.
Handouts and takeaways. A small stack of business cards, a one-page handout (often a reduced-size printout of the poster itself), or simply the QR code doing that job digitally, lets an interested visitor take something away without needing to photograph the whole board. Many presenters now rely on the QR code alone rather than printing physical handouts, but conference norms and audience expectations vary by field.
Stay near the poster for the full assigned block. Session organizers and evaluators (for judged poster competitions) generally expect the presenter to be present and attentive for the entire scheduled time, not just the busiest stretch.

Research-Administration Considerations for Posters

Beyond design and delivery, a handful of research-administration questions come up specifically around posters — these are less about how the poster looks and more about institutional and funder obligations attached to it.

Funder acknowledgement requirements

If the underlying study was funded by a grant, most funder agreements require that funding to be acknowledged on any public output describing the work — and a conference poster generally counts as such an output, not just the eventual journal article. Requirements typically specify exact wording, the grant or award number, and sometimes a funder logo or disclaimer language. Check the award terms directly rather than assuming a generic acknowledgement line is sufficient; CASRAI’s funding acknowledgement statement guide covers required elements and example wording by funder in detail.

Author order and affiliation conventions

The same author-order and affiliation conventions that apply to a manuscript byline generally apply to a poster byline — author order signals relative contribution or role by field convention, and each author’s institutional affiliation should be listed accurately and consistently with how it appears on the underlying study’s other outputs. See CASRAI’s author affiliation entry and corresponding-author line formatting guide. Where a poster is presented by someone other than the first or corresponding author (common when a student or trainee presents work from a larger lab), it’s still worth being explicit about who the presenter is versus who holds primary authorship credit, since conference programs and attendees will often address questions to whoever is standing at the board.

Does a poster count as a publication for CVs and reporting?

Conventionally, no — a conference poster is listed on a CV or biosketch as a presentation or conference contribution, in a separate section from peer-reviewed publications, not folded into the publications list itself. This distinction matters for funder progress reports and institutional research-output reporting (e.g. annual activity reports, promotion and tenure dossiers, or systems like Researchfish), which typically track presentations and publications as separate output categories with different expectations for peer review and permanence. A poster can still be a legitimate, reportable scholarly output — it simply isn’t equivalent to a peer-reviewed article, and presenting it that way risks misrepresenting the work’s review status.

Posting a poster to a repository, DOIs, and prior-publication rules

It has become increasingly common to deposit a poster PDF to a repository or platform (an institutional repository, Zenodo, F1000Research, or similar) so it has a durable, citable record independent of the conference itself. As of Crossref’s schema 5.5 (generally available 2024), “poster” is an explicit posted-content sub-type, meaning a deposited poster can be assigned its own Crossref DOI, distinct from any subsequent journal article DOI for the same study. Presenting preliminary findings at a conference — including via a poster, an abstract, or a DOI-bearing poster deposit — is not generally treated by journals or under ICMJE-aligned prior-publication norms as a bar to later submitting the completed, peer-reviewed manuscript; conference disclosure of preliminary work is a long-recognized exception to redundant-publication concerns, distinct from posting a complete manuscript as a preprint or duplicating an already-published paper. That said, individual journals set their own submission policies, so it’s worth checking a target journal’s specific instructions to authors if there’s any doubt — CASRAI’s guide to avoiding a prior-publication conflict covers the same underlying principles in more depth for preprints specifically.

How a Poster Relates to the Abstract and Manuscript Behind It

A poster is one of several distinct outputs describing the same underlying study, and it’s worth being clear about how they differ: the conference abstract is the short, text-only summary submitted to be accepted into the session in the first place (see also CASRAI’s guides on submitting a conference abstract and a sample conference abstract); a graphical abstract is a single-image visual summary increasingly requested alongside journal submissions, distinct from a poster in both purpose and format; and the poster itself is the full visual presentation delivered in person (or virtually) at the conference, generally produced after the abstract has already been accepted. None of the three substitutes for the others, and conference and journal requirements for each are set independently.

Frequently Asked Questions

What is a research poster?

A research poster is a large-format, single-page visual summary of a study — typically covering the background, methods, results, and conclusions — designed to be displayed on a board and discussed in person during a conference poster session, as distinct from a spoken conference talk or the full written journal manuscript.

What size should a research poster be?

There is no universal standard — check your specific conference’s presenter instructions. The most common sizes are 36 x 48 inches landscape (North American conferences) and A0 (84.1 x 118.9 cm, most European/international conferences), but boards and required orientation vary by venue.

What sections does a research poster need?

Most posters include a title, author/affiliation line, background, methods, results, conclusions, a short reference list, acknowledgements, a funding statement, and a QR code or contact details — though exact structure and ordering vary by field and by whether the poster follows a traditional IMRaD grid or a single-finding “Better Poster” layout.

Is the “Better Poster” format better than a traditional layout?

It depends on your field and venue. The Better Poster approach (a large central takeaway message plus a QR code to full detail) is well suited to fast-paced poster sessions where most visitors only stop briefly, but the traditional IMRaD-ordered grid remains the expected format at many conferences and among many mentors and reviewers. Check what’s typical for your target conference before choosing.

Does presenting a poster count as prior publication?

Generally no. Presenting preliminary findings at a conference, including via a poster or abstract, is a long-recognized exception to redundant-publication and prior-publication concerns under ICMJE-aligned norms, and doesn’t typically bar later journal submission of the full manuscript — though individual journals set their own policies, so check the target journal’s instructions to authors if in doubt.

Does a research poster count as a publication on a CV?

Conventionally no — it’s listed as a presentation or conference contribution, in a section separate from peer-reviewed publications, since it hasn’t gone through the same peer-review process.

Should I put a QR code on my poster, and what should it link to?

Yes, in most current practice — typically linking to a preprint of the full manuscript, the underlying dataset, a downloadable PDF of the poster, or the presenter’s ORCID iD. Test the code with a phone camera at its final printed size before the poster is printed, and label what it links to.

What resolution should images be for a printed poster?

Check resolution at the image’s final printed size, not its size on screen — an image that appears sharp at a small size on a monitor is often far below usable print resolution once scaled up to fill several inches of a 36-48 inch-wide poster. Confirm your printer’s specific DPI and color-mode (CMYK vs. RGB) requirements before submitting the final file.
