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, SVG) 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:

latex

% 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:

latex

\usetheme{Berlin}
\usecolortheme{beaver}

tikzposter:

latex

\usetheme{Rays}

}

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

\renewcommand{\familydefault}{\sfdefault}

Text Sizing:

\setbeamerfont{institute}{size=\normalsize}

Emphasis and Highlighting:

Color highlights sparingly: \textcolor{blue}{highlight}
Boxes for critical information
Avoid italics (harder to read from distance)
