LaTeX Research Posters
Overview
Research posters are a critical medium for scientific communication at conferences, symposia, and academic events. This skill provides guidance for creating professional, visually appealing research posters using LaTeX. It is organized as a concise router: the sections below cover the workflow and the key decisions, and link to detailed reference files for templates, figures, and quality control.
When to Use This Skill
Use this skill when:
- Creating research posters for conferences, symposia, or poster sessions
- Designing academic posters for university events or thesis defenses
- Preparing visual summaries of research for public engagement
- Converting a scientific paper into poster format
- Building template posters for a research group or department
- Designing posters to specific size requirements (A0, A1, 36×48", etc.)
- Building complex multi-column layouts that integrate figures, tables, equations, and citations
Reference Files
Detailed guidance lives in references/. Load the file relevant to your current step:

Ready-to-use starter templates live in assets/ (beamerposter_template.tex,
tikzposter_template.tex, baposter_template.tex, plus a quality checklist).
Choosing a LaTeX Package
| Package | Strengths | Best for |
|---|
| beamerposter | Beamer syntax, strong theme/branding support | Traditional academic posters, institutional branding |
| tikzposter | Modern, flexible, built-in color themes, TikZ graphics | Colorful, modern designs with custom graphics |
| baposter | Box-based layout, automatic spacing | Structured, professional multi-column layouts |
See references/latex_poster_packages.md for a full comparison, and the matching
templates_*.md reference for setup snippets.
Poster Sizes
International: A0 (841 × 1189 mm / 33.1 × 46.8 in, most common), A1 (594 × 841 mm), A2 (420 × 594 mm).
North American: 36 × 48 in (common US size), 42 × 56 in, 48 × 72 in.
Orientation: portrait (most common) or landscape (better for wide content and timelines).
Always confirm the conference's required size and orientation before starting.
Poster Structure and Layout
Common sections: Header/Title (title, authors, affiliations, logos), Introduction/Background, Methods/Approach, Results, Conclusions, References (abbreviated), Acknowledgments.
Layout strategies:
- Column-based grids (2, 3, or 4 columns) or flexible block-based arrangements.
- Z-pattern flow to guide the reader logically through the content.
- Visual hierarchy via size, color, and spacing to emphasize key points.
See references/poster_layout_design.md for grid systems and visual flow.
Design Principles
Typography — Title 72-120pt, section headers 48-72pt, body text 24-36pt minimum (readable from 4-6 feet). Prefer sans-serif (Arial, Helvetica, Calibri); limit to 2-3 font families.
Color and contrast — High-contrast schemes; color-blind-friendly palettes (avoid red-green); use institutional colors for branding. White space is active space — don't overcrowd.
Content — Less is more: 300-800 words total. Bullet points over paragraphs; clear, concise messaging; self-explanatory figures. Aim for a roughly even balance of visual and text area.
See references/poster_design_principles.md and references/poster_content_guide.md
for depth. Color palettes worth knowing: Viridis, ColorBrewer, and IBM Color Blind Safe.
Figures and Visuals
Figures carry most of a poster's communicative weight, so plan them deliberately.
If a diagram or figure would aid comprehension, invoke the alterlab-scientific-schematics
skill (diagrams/schematics) or the alterlab-generate-image skill (images). Figures are
optional — add them only where they improve clarity.
Keep each graphic to one message with a few large, high-contrast elements; split anything
complex into several simple images so the text stays readable from a distance. Full guidance —
planning, generating, reviewing, sizing, integrating with \includegraphics, and QR codes —
is in references/figures_and_visuals.md.
Workflow
1. Plan and develop content
- Confirm conference size, orientation, and format requirements.
- Identify 1-3 core messages and select the key figures (typically 3-6 main visuals).
- Draft concise, bullet-style text per section; aim for 300-800 words total.
- Choose a package (see the table above).
2. Prepare visual elements
- Plan the figures each section needs (see
references/figures_and_visuals.md).
- Generate them via the alterlab-scientific-schematics or alterlab-generate-image
skills where they add clarity, keeping each one simple and legible at a distance.
- Review each figure at ~25% zoom; simplify and regenerate any that read as cluttered.
3. Design and lay out
- Start from a template in
assets/; customize the color scheme to match branding.
- Plan the column structure and content flow (typically left-to-right, top-to-bottom).
- Allocate space: title ~10-15%, content ~70-80%, footer ~5-10%.
- Set the typography hierarchy and verify readability from 4-6 feet.
4. Integrate content
- Build the header (concise title, authors, affiliations, high-res logos).
- Place figures in their sections with sensible sizing (
width=0.85\linewidth, not full width).
- Add minimal, scannable supporting text in active voice; complement figures, don't duplicate them.
- Add QR codes, key references (5-10 typical), contact info, and acknowledgments.
5. Compile, review, and deliver
- Compile (
pdflatex / lualatex / xelatex) — see references/compilation_and_qc.md.
- Run the overflow check on the log and inspect all four edges at 100% zoom.
- Do a 25%-scale print test, verify fonts are embedded and images are 300 DPI, and proofread.
- Prepare print output (PDF/X-1a, CMYK if required, bleed if required) and a PNG/handout version.
Compilation and Quality Control
Compile, prevent overflow, and run the pre-print checklist using
references/compilation_and_qc.md. The single most important check: after every compile,
run grep -i "overfull" poster.log and visually inspect all four page edges — overflow
(text or graphics cut off at a boundary) is the most common poster defect. A helper script
is available at scripts/review_poster.sh.
Common Pitfalls to Avoid
Design — Too much text (>1000 words); body text under 24pt; low-contrast colors; cluttered layout with no white space; inconsistent styling; pixelated images.
Figures — Cramming too many elements into one graphic (forces tiny text); too much detail; complex flowcharts with many steps; comparison charts with too many series. Split into simple, focused graphics instead.
Content — No clear narrative; too many research questions; unexplained jargon; results without interpretation; missing contact information.
Technical — Wrong dimensions for the conference; RGB sent to a CMYK printer (color shift); fonts not embedded; file too large for the submission portal; QR codes too small or untested.
Integration with Other Skills
- alterlab-scientific-schematics — generate poster diagrams and flowcharts.
- alterlab-generate-image — stylized graphics, conceptual illustrations, summary visuals.
- alterlab-scientific-writing — develop poster content from a paper.
- alterlab-literature-review — contextualize the research.
Package Installation
tlmgr install beamerposter tikzposter

baposter is not on CTAN/TeX Live. Obtain baposter.cls from its repository
(github.com/mloesch/baposter) or the Overleaf template and place it next to your
.tex file. (CTAN's xebaposter is a separate Persian/Latin fork, not the same class.)
Scripts
