baposter:

• Box-based layout system
• Automatic spacing and positioning
• Professional-looking default styles
• Best for: Multi-column layouts, consistent spacing

2. Poster Layout and Structure

Create effective poster layouts following visual communication principles. For comprehensive layout guidance, refer to references/poster_layout_design.md.

Common Poster Sections:

• Header/Title: Title, authors, affiliations, logos
• Introduction/Background: Research context and motivation
• Methods/Approach: Methodology and experimental design
• Results: Key findings with figures and data visualizations
• Conclusions: Main takeaways and implications
• References: Key citations (typically abbreviated)
• Acknowledgments: Funding, collaborators, institutions

Layout Strategies:

• Column-based layouts: 2-column, 3-column, or 4-column grids
• Block-based layouts: Flexible arrangement of content blocks
• Z-pattern flow: Guide readers through content logically
• Visual hierarchy: Use size, color, and spacing to emphasize key points

3. Design Principles for Research Posters

Apply evidence-based design principles for maximum impact. For detailed design guidance, refer to references/poster_design_principles.md.

Typography:

• Title: 72-120pt for visibility from distance
• Section headers: 48-72pt
• Body text: 24-36pt minimum for readability from 4-6 feet
• Use sans-serif fonts (Arial, Helvetica, Calibri) for clarity
• Limit to 2-3 font families maximum

Color and Contrast:

• Use high-contrast color schemes for readability
• Institutional color palettes for branding
• Color-blind friendly palettes (avoid red-green combinations)
• White space is active space—don't overcrowd

Visual Elements:

• High-resolution figures (300 DPI minimum for print)
• Large, clear labels on all figures
• Consistent figure styling throughout
• Strategic use of icons and graphics
• Balance text with visual content (40-50% visual recommended)

Content Guidelines:

• Less is more: 300-800 words total recommended
• Bullet points over paragraphs for scannability
• Clear, concise messaging
• Self-explanatory figures with minimal text explanation
• QR codes for supplementary materials or online resources

4. Standard Poster Sizes

Support for international and conference-specific poster dimensions:

International Standards:

• A0 (841 × 1189 mm / 33.1 × 46.8 inches) - Most common European standard
• A1 (594 × 841 mm / 23.4 × 33.1 inches) - Smaller format
• A2 (420 × 594 mm / 16.5 × 23.4 inches) - Compact posters

North American Standards:

• 36 × 48 inches (914 × 1219 mm) - Common US conference size
• 42 × 56 inches (1067 × 1422 mm) - Large format
• 48 × 72 inches (1219 × 1829 mm) - Extra large

Orientation:

• Portrait (vertical) - Most common, traditional
• Landscape (horizontal) - Better for wide content, timelines

5. Package-Specific Templates

Provide ready-to-use templates for each major package. Templates available in assets/ directory.

beamerposter Templates:

• beamerposter_template.tex - Customizable beamerposter template

tikzposter Templates:

• tikzposter_template.tex - Customizable tikzposter template

baposter Templates:

• baposter_template.tex - Customizable baposter template

6. Figure and Image Integration

Optimize visual content for poster presentations:

Best Practices:

• Use vector graphics (PDF; convert SVG to PDF before inclusion) when possible for scalability
• Raster images: minimum 300 DPI at final print size
• Consistent image styling (borders, captions, sizes)
• Group related figures together
• Use subfigures for comparisons

LaTeX Figure Commands:

% Include graphics package
\usepackage{graphicx}

% Simple figure
\includegraphics[width=0.8\linewidth]{figure.pdf}

% Figure with caption in tikzposter
\block{Results}{
  \begin{tikzfigure}
    \includegraphics[width=0.9\linewidth]{results.png}
  \end{tikzfigure}
}

% Multiple subfigures
\usepackage{subcaption}
\begin{figure}
  \begin{subfigure}{0.48\linewidth}
    \includegraphics[width=\linewidth]{fig1.pdf}
    \caption{Condition A}
  \end{subfigure}
  \begin{subfigure}{0.48\linewidth}
    \includegraphics[width=\linewidth]{fig2.pdf}
    \caption{Condition B}
  \end{subfigure}
\end{figure}

7. Color Schemes and Themes

Provide professional color palettes for various contexts:

Academic Institution Colors:

• Match university or department branding
• Use official color codes (RGB, CMYK, or LaTeX color definitions)

Scientific Color Palettes (color-blind friendly):

• Viridis: Professional gradient from purple to yellow
• ColorBrewer: Research-tested palettes for data visualization
• IBM Color Blind Safe: Accessible corporate palette

Package-Specific Theme Selection:

beamerposter:

\usetheme{Berlin}
\usecolortheme{beaver}

tikzposter:

\usetheme{Rays}
\usecolorstyle{Denmark}

baposter:

\begin{poster}{
  background=plain,
  bgColorOne=white,
  headerColorOne=blue!70,
  textborder=rounded
}

8. Typography and Text Formatting

Ensure readability and visual appeal:

Font Selection:

% Sans-serif fonts recommended for posters
\usepackage{helvet}      % Helvetica
\usepackage{avant}       % Avant Garde
\usepackage{sfmath}      % Sans-serif math fonts

% Set default to sans-serif
\renewcommand{\familydefault}{\sfdefault}

Text Sizing:

% Adjust text sizes for visibility
\setbeamerfont{title}{size=\VeryHuge}
\setbeamerfont{author}{size=\Large}
\setbeamerfont{institute}{size=\normalsize}

Emphasis and Highlighting:

• Use bold for key terms: \textbf{important}
• Color highlights sparingly: \textcolor{blue}{highlight}
• Boxes for critical information
• Avoid italics (harder to read from distance)

9. QR Codes and Interactive Elements

Enhance poster interactivity for modern conferences:

QR Code Integration:

\usepackage{qrcode}

% Link to paper, code repository, or supplementary materials
\qrcode[height=2cm]{https://github.com/username/project}

% QR code with caption
\begin{center}
  \qrcode[height=3cm]{https://doi.org/10.1234/paper}\\
  \small Scan for full paper
\end{center}

Digital Enhancements:
