LaTeX Research Posters

Overview

Research posters are a critical medium for scientific communication at conferences, symposia, and academic events. This knowhow covers end-to-end poster creation in LaTeX: package selection, layout design, typography, color schemes, figure integration, accessibility, compilation, and quality control for print and digital display.

Key Concepts

1. LaTeX Poster Packages

Three major packages, each with distinct strengths:

| Package | Architecture | Best For | Learning Curve | |---------|-------------|----------|---------------| | **beamerposter** | Beamer extension | Traditional academic posters, institutional branding | Low (if you know Beamer) | | **tikzposter** | TikZ-based blocks | Modern colorful designs, custom graphics | Medium | | **baposter** | Box-based grid | Multi-column layouts, consistent spacing | Low |

**beamerposter**: Uses Beamer's `\begin{block}` syntax. Themes and color schemes from Beamer carry over. Best when your institution already has a Beamer theme.

**tikzposter**: Declarative block placement with `\block{Title}{Content}`. Built-in color styles (Denmark, Germany, etc.) and layout themes (Rays, Wave). Most flexible for custom designs.

**baposter**: Defines named boxes in a grid. Automatic positioning and spacing. Best when you want structured, uniform column layouts without manual placement.

2. Poster Dimensions and Orientation

| Standard | Size | Region | Use | |----------|------|--------|-----| | **A0** | 841 × 1189 mm (33.1 × 46.8 in) | Europe | Most common academic standard | | **A1** | 594 × 841 mm (23.4 × 33.1 in) | Europe | Smaller venues | | **36 × 48 in** | 914 × 1219 mm | North America | Standard US conference size | | **42 × 56 in** | 1067 × 1422 mm | North America | Large format | | **48 × 72 in** | 1219 × 1829 mm | North America | Extra large |

**Orientation**: Portrait (vertical) is most common and traditional. Landscape (horizontal) works better for timelines, wide figures, or side-by-side comparisons.

3. Typography Rules

| Element | Size Range | Purpose | |---------|-----------|---------| | Title | 72–120 pt | Readable from 15+ feet | | Section headers | 48–72 pt | Readable from 8–10 feet | | Body text | 24–36 pt | Readable from 4–6 feet | | Captions | 20–28 pt | Readable from 3 feet |

• Use **sans-serif** fonts (Helvetica, Calibri, Arial) for poster readability
• Limit to **2–3 font families** maximum
• Avoid italics (harder to read from distance)
• Use bold for emphasis, not underlining

4. Visual Content Guidelines

• **40–50% of poster area** should be visual content (figures, diagrams, tables)
• **300 DPI minimum** for raster images at final print size
• Use **vector graphics** (PDF, SVG) whenever possible for scalability
• Target **3–6 main figures** per poster
• Total text: **300–800 words** (less is more)

Decision Framework

Package Selection

Start: What is your design priority?
├── Institutional branding / existing Beamer theme?
│   └── YES → beamerposter
├── Modern, colorful, custom TikZ graphics?
│   └── YES → tikzposter
├── Structured multi-column grid with minimal setup?
│   └── YES → baposter
└── Not sure
    └── tikzposter (most flexible default)

Layout Decision Table

| Poster Content | Columns | Layout Strategy | |---------------|---------|-----------------| | Few key results, large figures | 2 columns | Wide figure panels, brief text | | Balanced text and figures | 3 columns | Standard academic layout | | Data-heavy with many small figures | 4 columns | Compact grid, small text | | Narrative flow / timeline | 2 columns landscape | Left-to-right story |

Content vs Visual Balance

| Poster Type | Text % | Visual % | Word Count | |-------------|--------|----------|------------| | Experimental research | 40% | 60% | 400–600 | | Computational/modeling | 50% | 50% | 500–700 | | Review/survey | 55% | 45% | 600–800 | | Method paper | 35% | 65% | 300–500 |

Best Practices

1. **MANDATORY: Every poster must include at least 2 figures.** Posters are primarily visual media — text-heavy posters fail to communicate. Target 3–4 figures for comprehensive posters: methodology diagram, key results, conceptual framework.

2. **MANDATORY: Verify poster dimensions match conference requirements exactly.** Use `pdfinfo poster.pdf | grep "Page size"` after compilation. A0 should show ~2384 × 3370 points.

3. **Follow the Z-pattern reading flow.** Place the most important content (title, key result figure) in the top-left quadrant. Readers naturally scan: top-left → top-right → bottom-left → bottom-right.

4. **Use white space intentionally.** White space is not wasted space — it improves readability and visual hierarchy. Don't fill every gap with text.

5. **Keep text scannable.** Use bullet points instead of paragraphs. Each section should be understandable in under 30 seconds.

6. **Anti-pattern — cramming the full paper into poster format.** A poster is not a shrunken paper. Extract 1–3 key messages and design around those. Leave details for the handout or QR-linked paper.

7. **Test readability at reduced scale.** Print at 25% scale on letter/A4 paper. If the title isn't readable from 6 feet, the body text isn't readable from 2 feet, or figures are unclear, revise.

8. **Use color-blind friendly palettes.** Avoid red-green combinations (affects ~8% of males). Use Viridis, ColorBrewer, or IBM Color Blind Safe palettes. Add patterns or shapes alongside color coding.

9. **Embed all fonts in the final PDF.** Run `pdffonts poster.pdf` — every font should show "yes" in the "emb" column. Non-embedded fonts may render differ
