Latex Posters

LaTeX Research Posters

Overview

Research posters are a critical medium for scientific communication at conferences, symposia, and academic events. This skill provides comprehensive guidance for creating professional, visually appealing research posters using LaTeX packages. Generate publication-quality posters with proper layout, typography, color schemes, and visual hierarchy.

When to Use This Skill

This skill should be used 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 scientific papers into poster format
• Creating template posters for research groups or departments
• Designing posters that comply with specific conference size requirements (A0, A1, 36×48", etc.)
• Building posters with complex multi-column layouts
• Integrating figures, tables, equations, and citations in poster format

AI-Powered Visual Element Generation

STANDARD WORKFLOW: Generate ALL major visual elements using AI before creating the LaTeX poster.

This is the recommended approach for creating visually compelling posters:

1. Plan all visual elements needed (title, intro, methods, results, conclusions)
2. Generate each element using scientific-schematics or Nano Banana Pro
3. Assemble generated images in the LaTeX template
4. Add text content around the visuals

Target: 60-70% of poster area should be AI-generated visuals, 30-40% text.

CRITICAL: Poster-Size Font Requirements

⚠️ ALL text within AI-generated visualizations MUST be poster-readable.

When generating graphics for posters, you MUST include font size specifications in EVERY prompt. Poster graphics are viewed from 4-6 feet away, so text must be LARGE.

⚠️ COMMON PROBLEM: Content Overflow and Density

The #1 issue with AI-generated poster graphics is TOO MUCH CONTENT. This causes:

• Text overflow beyond boundaries
• Unreadable small fonts
• Cluttered, overwhelming visuals
• Poor white space usage

SOLUTION: Generate SIMPLE graphics with MINIMAL content.

Required prompt additions for poster graphics:

POSTER FORMAT REQUIREMENTS:
- MAXIMUM 3-5 elements per graphic (NOT 10+)
- MAXIMUM 10-15 words total per graphic
- ALL text must be VERY LARGE and bold (readable from 6 feet away)
- Title text: minimum 72pt equivalent, bold
- Key metrics/numbers: minimum 60pt equivalent, bold  
- Labels and captions: minimum 36pt equivalent
- Use high contrast (dark text on light background or vice versa)
- GENEROUS white space (40-50% of graphic should be empty)
- Large icons and graphics with thick lines
- ONE main message per graphic

Content limits per graphic type:

Example - WRONG (too much content, text too small):

# BAD - too complex, too many elements, no size specs
python scripts/generate_schematic.py "Infographic showing machine learning pipeline with data collection, preprocessing, feature extraction, model training, validation, hyperparameter tuning, testing, deployment, monitoring, and feedback loops. Include accuracy metrics, performance graphs, comparison tables, and technical specifications." -o figures/pipeline.png
# Result: Cluttered graphic with tiny unreadable text, overflow issues

Example - CORRECT (simple, poster-appropriate):

# GOOD - minimal content, explicit size requirements, generous spacing
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE flowchart with ONLY 4 boxes: DATA → MODEL → PREDICT → RESULT. Each box label in GIANT bold text (80pt+). Thick arrows between boxes. GENEROUS white space (50% empty). High contrast. Maximum 4 words per box. Readable from 8 feet." -o figures/pipeline.png
# Result: Clean, readable graphic with large text

Example - WRONG (key findings too complex):

# BAD - too many items, too much detail
python scripts/generate_schematic.py "Key findings showing 8 metrics: accuracy 95%, precision 92%, recall 94%, F1 0.93, AUC 0.97, training time 2.3 hours, inference 50ms, model size 145MB with comparison to 5 baseline methods" -o figures/findings.png
# Result: Cramped graphic with tiny numbers

Example - CORRECT (key findings simple):

# GOOD - only 3 key items, giant numbers
python scripts/generate_schematic.py "POSTER FORMAT for A0. KEY FINDINGS with ONLY 3 large cards. Card 1: '95%' in GIANT text (120pt) with 'ACCURACY' below (48pt). Card 2: '2X' in GIANT text with 'FASTER' below. Card 3: checkmark icon with 'VALIDATED' in large text. 50% white space. High contrast colors. NO other text or details." -o figures/findings.png
# Result: Bold, readable impact statement

Font size reference for poster prompts:

Always include in prompts:

• "POSTER FORMAT" or "for A0 poster" or "readable from 6 feet"
• "VERY LARGE TEXT" or "huge bold fonts"
• Specific text that should appear (so it's baked into the image)
• "minimal text, maximum impact"
• "high contrast" for readability

Step 1: Plan Your Poster Elements

Before creating the LaTeX poster, identify all visual elements needed:

1. Title Block - Stylized title with institutional branding (optional - can be LaTeX text)
2. Introduction Graphic - Conceptual overview or problem statement visual
3. Methods Diagram - Workflow, pipeline, or experimental design
4. Results Figures - Data visualizations, charts, key findings (2-4 figures)
5. Conclusion Graphic - Summary visual or take-home message
6. Supplementary Icons - Icons for sections, QR codes, logos

Step 2: Generate Each Element

Use the appropriate tool for each element type:

For Schematics and Diagrams (scientific-schematics):

# Create figures directory
mkdir -p figures

# Methods flowchart - SIMPLE, 4 steps only
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE flowchart with ONLY 4 boxes: DATA → PROCESS → MODEL → RESULTS. Each label in GIANT bold text (80pt+). Thick arrows. 50% white space. NO additional details or sub-steps. Readable from 8 feet." -o figures/methods_flowchart.png

# System architecture - SIMPLE, 4 components only
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE architecture diagram with ONLY 4 components: INPUT → NETWORK → PROCESSING → OUTPUT. GIANT labels (80pt+). Thick lines. 50% white space. NO layer details. Readable from 8 feet." -o figures/architecture.png

# Conceptual framework - SIMPLE, 3 elements only
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE diagram with ONLY 3 elements: A → B → C. Each label in GIANT bold text (80pt+). Thick arrows. 50% white space. NO additional text. Readable from 8 feet." -o figures/concept_framework.png

# Experimental design - SIMPLE, 3 groups only
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE design diagram: CONTROL vs TREATMENT with arrow to OUTCOMES. ONLY 3 boxes total. GIANT labels (80pt+). 50% white space. NO detailed sub-groups. Readable from 8 feet." -o figures/experimental_design.png

For Stylized Blocks and Graphics (Nano Banana Pro):

# Title block - SIMPLE
python scripts/generate_schematic.py "POSTER FORMAT for A0. Title block: 'ML FOR DRUG DISCOVERY' in HUGE bold text (120pt+). Dark blue background. ONE subtle icon. NO other text. 40% white space. Readable from 15 feet." -o figures/title_block.png

# Introduction visual - SIMPLE, 3 elements only
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE problem visual with ONLY 3 icons: drug icon, arrow, target icon. ONE label per icon (80pt+). 50% white space. NO detailed text. Readable from 8 feet." -o figures/intro_visual.png

# Conclusion/summary - ONLY 3 items, GIANT numbers
python scripts/generate_schematic.py "POSTER FORMAT for A0. KEY FINDINGS with EXACTLY 3 cards only. Card 1: '95%' (150pt font) with 'ACCURACY' (60pt). Card 2: '2X' (150pt) with 'FASTER' (60pt). Card 3: checkmark icon with 'READY' (60pt). 50% white space. NO other text. Readable from 10 feet." -o figures/conclusions_graphic.png

# Background visual - SIMPLE, 3 icons only
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE visual with ONLY 3 large icons in a row: problem icon → challenge icon → impact icon. ONE word label each (80pt+). 50% white space. NO detailed text. Readable from 8 feet." -o figures/background_visual.png

For Data Visualizations - SIMPLE, 3 bars max:

# SIMPLE chart with ONLY 3 bars, GIANT labels
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE bar chart with ONLY 3 bars: BASELINE (70%), EXISTING (85%), OURS (95%). GIANT percentage labels ON the bars (100pt+). NO axis labels, NO legend, NO gridlines. Our bar highlighted in different color. 40% white space. Readable from 8 feet." -o figures/comparison_chart.png

Step 3: Assemble in LaTeX Template

Include all generated figures in your poster template:

tikzposter example:

\documentclass[25pt, a0paper, portrait]{tikzposter}

\begin{document}

\maketitle

\begin{columns}
\column{0.5}

\block{Introduction}{
  \centering
  \includegraphics[width=0.85\linewidth]{figures/intro_visual.png}
  
  \vspace{0.5em}
  Brief context text here (2-3 sentences max).
}

\block{Methods}{
  \centering
  \includegraphics[width=0.9\linewidth]{figures/methods_flowchart.png}
}

\column{0.5}

\block{Results}{
  \begin{minipage}{0.48\linewidth}
    \centering
    \includegraphics[width=\linewidth]{figures/result_1.png}
  \end{minipage}
  \hfill
  \begin{minipage}{0.48\linewidth}
    \centering
    \includegraphics[width=\linewidth]{figures/result_2.png}
  \end{minipage}
  
  \vspace{0.5em}
  Key findings in 3-4 bullet points.
}

\block{Conclusions}{
  \centering
  \includegraphics[width=0.8\linewidth]{figures/conclusions_graphic.png}
}

\end{columns}

\end{document}

baposter example:

\headerbox{Methods}{name=methods,column=0,row=0}{
  \centering
  \includegraphics[width=0.95\linewidth]{figures/methods_flowchart.png}
}

\headerbox{Results}{name=results,column=1,row=0}{
  \includegraphics[width=\linewidth]{figures/comparison_chart.png}
  \vspace{0.3em}
  
  Key finding: Our method achieves 92% accuracy.
}

Example: Complete Poster Generation Workflow

Remember: SIMPLE graphics with MINIMAL content. Each graphic = ONE message.

# 1. Create figures directory
mkdir -p figures

# 2. Generate SIMPLE visual elements - MAXIMUM 5 elements per graphic

# Problem statement - ONLY 3 icons
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE visual with 3 icons only: PATIENT icon → DELAY icon → RISK icon. ONE word label each (80pt+). 50% white space. Readable from 8 feet." -o figures/problem.png

# Methods pipeline - ONLY 4 steps
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE flowchart with ONLY 4 boxes: IMAGES → PROCESS → MODEL → DIAGNOSIS. GIANT labels (100pt+). Thick arrows. 50% white space. NO sub-steps. Readable from 8 feet." -o figures/methods.png

# Architecture diagram - ONLY 4 components  
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE architecture with ONLY 4 blocks: INPUT → CNN → DENSE → OUTPUT. GIANT labels (80pt+). Thick lines. 50% white space. NO layer details. Readable from 8 feet." -o figures/architecture.png

# Results - ONLY 3 bars
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE bar chart with ONLY 3 bars: 82% BASELINE, 88% EXISTING, 95% OURS (highlighted). GIANT percentages ON bars (120pt+). NO axis, NO legend. 40% white space. Readable from 10 feet." -o figures/results.png

# Key findings - ONLY 3 items with GIANT numbers
python scripts/generate_schematic.py "POSTER FORMAT for A0. EXACTLY 3 cards only: '95%' (150pt) 'ACCURACY' (60pt), '2X' (150pt) 'FASTER' (60pt), checkmark 'VALIDATED' (60pt). 50% white space. NO other text. Readable from 10 feet." -o figures/conclusions.png

# 3. Compile LaTeX poster with all figures
pdflatex poster.tex

If graphics still overflow or have small text:

1. Reduce number of elements further (try 3 instead of 5)
2. Add "EVEN SIMPLER" or "ONLY 3 elements" to prompt
3. Increase font size requirements (try 150pt+ for key numbers)
4. Add "60% white space" instead of 50%

Visual Element Guidelines

⚠️ CRITICAL: Each graphic should have ONE main message and MINIMAL content.

Content limits - NEVER exceed these:

• Maximum 5 boxes/elements per flowchart
• Maximum 3-4 bars per chart
• Maximum 3 key findings per infographic
• Maximum 15 words total per graphic
• 50% white space minimum

For each poster section, generate SIMPLE visuals with POSTER FORMAT:

MANDATORY prompt elements for poster graphics:

1. "POSTER FORMAT for A0" - size indicator
2. "SIMPLE" or "ONLY X elements" - content limit
3. "GIANT (80pt+)" or "HUGE (100pt+)" - font sizes
4. "50% white space" - prevent crowding
5. "readable from 6-8 feet" - viewing distance
6. Exact text that should appear (keep minimal!)

ANTI-PATTERNS TO AVOID:

• ❌ "Show all the steps in the methodology" → Too many elements
• ❌ "Include accuracy, precision, recall, F1, AUC" → Too many metrics
• ❌ "Comparison of 6 different methods" → Too many comparisons
• ❌ "Detailed architecture with all layers" → Too complex

CORRECT PATTERNS:

• ✅ "ONLY 4 main steps" → Limited elements
• ✅ "ONLY the top 3 metrics" → Focused content
• ✅ "Compare ONLY our method vs baseline" → Simple comparison
• ✅ "HIGH-LEVEL architecture with 4 components" → Simplified view

Ensuring Full Page Coverage:

Posters should use the entire page without excessive margins. Configure packages correctly:

beamerposter - Full Page Setup:

\documentclass[final,t]{beamer}
\usepackage[size=a0,scale=1.4,orientation=portrait]{beamerposter}

% Remove default beamer margins
\setbeamersize{text margin left=0mm, text margin right=0mm}

% Use geometry for precise control
\usepackage[margin=10mm]{geometry}  % 10mm margins all around

% Remove navigation symbols
\setbeamertemplate{navigation symbols}{}

% Remove footline and headline if not needed
\setbeamertemplate{footline}{}
\setbeamertemplate{headline}{}

tikzposter - Full Page Setup:

\documentclass[
  25pt,                      % Font scaling
  a0paper,                   % Paper size
  portrait,                  % Orientation
  margin=10mm,               % Outer margins (minimal)
  innermargin=15mm,          % Space inside blocks
  blockverticalspace=15mm,   % Space between blocks
  colspace=15mm,             % Space between columns
  subcolspace=8mm            % Space between subcolumns
]{tikzposter}

% This ensures content fills the page

baposter - Full Page Setup:

\documentclass[a0paper,portrait,fontscale=0.285]{baposter}

\begin{poster}{
  grid=false,
  columns=3,
  colspacing=1.5em,          % Space between columns
  eyecatcher=true,
  background=plain,
  bgColorOne=white,
  borderColor=blue!50,
  headerheight=0.12\textheight,  % 12% for header
  textborder=roundedleft,
  headerborder=closed,
  boxheaderheight=2em        % Consistent box header heights
}
% Content here
\end{poster}

Common Issues and Fixes:

Problem: Large white margins around poster

% Fix for beamerposter
\setbeamersize{text margin left=5mm, text margin right=5mm}

% Fix for tikzposter
\documentclass[..., margin=5mm, innermargin=10mm]{tikzposter}

% Fix for baposter - adjust in document class
\documentclass[a0paper, margin=5mm]{baposter}

Problem: Content doesn't fill vertical space

% Use \vfill between sections to distribute space
\block{Introduction}{...}
\vfill
\block{Methods}{...}
\vfill
\block{Results}{...}

% Or manually adjust block spacing
\vspace{1cm}  % Add space between specific blocks

Problem: Poster extends beyond page boundaries

% Check total width calculation
% For 3 columns with spacing:
% Total = 3×columnwidth + 2×colspace + 2×margins
% Ensure this equals \paperwidth

% Debug by adding visible page boundary
\usepackage{eso-pic}
\AddToShipoutPictureBG{
  \AtPageLowerLeft{
    \put(0,0){\framebox(\LenToUnit{\paperwidth},\LenToUnit{\paperheight}){}}
  }
}

Print Preparation:

• Generate PDF/X-1a for professional printing
• Embed all fonts
• Convert colors to CMYK if required
• Check resolution of all images (minimum 300 DPI)
• Add bleed area if required by printer (usually 3-5mm)
• Verify page size matches requirements exactly

Digital Display:

• RGB color space for screen display
• Optimize file size for email/web
• Test readability on different screens

11. PDF Review and Quality Control

CRITICAL: Always review the generated PDF before printing or presenting. Use this systematic checklist:

Step 1: Page Size Verification

# Check PDF dimensions (should match poster size exactly)
pdfinfo poster.pdf | grep "Page size"

# Expected outputs:
# A0: 2384 x 3370 points (841 x 1189 mm)
# 36x48": 2592 x 3456 points
# A1: 1684 x 2384 points (594 x 841 mm)

Step 2: Visual Inspection Checklist

Open PDF at 100% zoom and check:

Layout and Spacing:

• Content fills entire page (no large white margins)
• Consistent spacing between columns
• Consistent spacing between blocks/sections
• All elements aligned properly (use ruler tool)
• No overlapping text or figures
• White space evenly distributed

Typography:

• Title clearly visible and large (72pt+)
• Section headers readable (48-72pt)
• Body text readable at 100% zoom (24-36pt minimum)
• No text cutoff or running off edges
• Consistent font usage throughout
• All special characters render correctly (symbols, Greek letters)

Visual Elements:

• All figures display correctly
• No pixelated or blurry images
• Figure captions present and readable
• Colors render as expected (not washed out or too dark)
• Logos display clearly
• QR codes visible and scannable

Content Completeness:

• Title and authors complete
• All sections present (Intro, Methods, Results, Conclusions)
• References included
• Contact information visible
• Acknowledgments (if applicable)
• No placeholder text remaining (Lorem ipsum, TODO, etc.)

Technical Quality:

• No LaTeX compilation warnings in important areas
• All citations resolved (no [?] marks)
• All cross-references working
• Page boundaries correct (no content cut off)

Step 3: Reduced-Scale Print Test

Essential Pre-Printing Test:

# Create reduced-size test print (25% of final size)
# This simulates viewing full poster from ~8-10 feet

# For A0 poster, print on A4 paper (24.7% scale)
# For 36x48" poster, print on letter paper (~25% scale)

Print Test Checklist:

• Title readable from 6 feet away
• Section headers readable from 4 feet away
• Body text readable from 2 feet away
• Figures clear and understandable
• Colors printed accurately
• No obvious design flaws

Step 4: Digital Quality Checks

Font Embedding Verification:

# Check that all fonts are embedded (required for printing)
pdffonts poster.pdf

# All fonts should show "yes" in "emb" column
# If any show "no", recompile with:
pdflatex -dEmbedAllFonts=true poster.tex

Image Resolution Check:

# Extract image information
pdfimages -list poster.pdf

# Check that all images are at least 300 DPI
# Formula: DPI = pixels / (inches in poster)
# For A0 width (33.1"): 300 DPI = 9930 pixels minimum

File Size Optimization:

# For email/web, compress if needed (>50MB)
gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 \
   -dPDFSETTINGS=/printer -dNOPAUSE -dQUIET -dBATCH \
   -sOutputFile=poster_compressed.pdf poster.pdf

# For printing, keep original (no compression)

Step 5: Accessibility Check

Color Contrast Verification:

• Text-background contrast ratio ≥ 4.5:1 (WCAG AA)
• Important elements contrast ratio ≥ 7:1 (WCAG AAA)
• Test online: https://webaim.org/resources/contrastchecker/

Color Blindness Simulation:

• View PDF through color blindness simulator
• Information not lost with red-green simulation
• Use Coblis (color-blindness.com) or similar tool

Step 6: Content Proofreading

Systematic Review:

• Spell-check all text
• Verify all author names and affiliations
• Check all numbers and statistics for accuracy
• Confirm all citations are correct
• Review figure labels and captions
• Check for typos in headers and titles

Peer Review:

• Ask colleague to review poster
• 30-second test: Can they identify main message?
• 5-minute review: Do they understand conclusions?
• Note any confusing elements

Step 7: Technical Validation

LaTeX Compilation Log Review:

# Check for warnings in .log file
grep -i "warning\|error\|overfull\|underfull" poster.log

# Common issues to fix:
# - Overfull hbox: Text extending beyond margins

3. Methods: Literature search strategy
4. Key findings: Main themes (organized by category)
5. Trends: Visualizations of publication patterns
6. Gaps: Identified research needs
7. Conclusions: Summary and implications
8. References

12. Accessibility and Inclusive Design

Design posters that are accessible to diverse audiences:

Color Blindness Considerations:

• Avoid red-green combinations (most common color blindness)
• Use patterns or shapes in addition to color
• Test with color-blindness simulators
• Provide high contrast (WCAG AA standard: 4.5:1 minimum)

Visual Impairment Accommodations:

• Large, clear fonts (minimum 24pt body text)
• High contrast text and background
• Clear visual hierarchy
• Avoid complex textures or patterns in backgrounds

Language and Content:

• Clear, concise language
• Define acronyms and jargon
• International audience considerations
• Consider multilingual QR code options for global conferences

13. Poster Presentation Best Practices

Guidance beyond LaTeX for effective poster sessions:

Content Strategy:

• Tell a story, don't just list facts
• Focus on 1-3 main messages
• Use visual abstract or graphical summary
• Leave room for conversation (don't over-explain)

Physical Presentation Tips:

• Bring printed handouts or business cards with QR code
• Prepare 30-second, 2-minute, and 5-minute verbal summaries
• Stand to the side, not blocking the poster
• Engage viewers with open-ended questions

Digital Backups:

• Save poster as PDF on mobile device
• Prepare digital version for email sharing
• Create social media-friendly image version
• Have backup printed copy or digital display option

Workflow for Poster Creation

Stage 1: Planning and Content Development

1. Determine poster requirements:

   • Conference size specifications (A0, 36×48", etc.)
   • Orientation (portrait vs. landscape)
   • Submission deadlines and format requirements

2. Develop content outline:

   • Identify 1-3 core messages
   • Select key figures (typically 3-6 main visuals)
   • Draft concise text for each section (bullet points preferred)
   • Aim for 300-800 words total

3. Choose LaTeX package:

   • beamerposter: If familiar with Beamer, need institutional themes
   • tikzposter: For modern, colorful designs with flexibility
   • baposter: For structured, professional multi-column layouts

Stage 2: Generate Visual Elements (AI-Powered)

CRITICAL: Generate SIMPLE figures with MINIMAL content. Each graphic = ONE message.

Content limits:

• Maximum 4-5 elements per graphic
• Maximum 15 words total per graphic
• 50% white space minimum
• GIANT fonts (80pt+ for labels, 120pt+ for key numbers)

1. Create figures directory:

   mkdir -p figures
   

2. Generate SIMPLE visual elements:

   # Introduction - ONLY 3 icons/elements
   python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE visual with ONLY 3 elements: [icon1] [icon2] [icon3]. ONE word labels (80pt+). 50% white space. Readable from 8 feet." -o figures/intro.png
   
   # Methods - ONLY 4 steps maximum
   python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE flowchart with ONLY 4 boxes: STEP1 → STEP2 → STEP3 → STEP4. GIANT labels (100pt+). 50% white space. NO sub-steps." -o figures/methods.png
   
   # Results - ONLY 3 bars/comparisons
   python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE chart with ONLY 3 bars. GIANT percentages ON bars (120pt+). NO axis, NO legend. 50% white space." -o figures/results.png
   
   # Conclusions - EXACTLY 3 items with GIANT numbers
   python scripts/generate_schematic.py "POSTER FORMAT for A0. EXACTLY 3 key findings: '[NUMBER]' (150pt) '[LABEL]' (60pt) for each. 50% white space. NO other text." -o figures/conclusions.png
   

3. Review generated figures - check for overflow:

   • View at 25% zoom: All text still readable?
   • Count elements: More than 5? → Regenerate simpler
   • Check white space: Less than 40%? → Add "60% white space" to prompt
   • Font too small?: Add "EVEN LARGER" or increase pt sizes
   • Still overflowing?: Reduce to 3 elements instead of 4-5

Stage 3: Design and Layout

1. Select or create template:

   • Start with provided templates in assets/
   • Customize color scheme to match branding
   • Configure page size and orientation

2. Design layout structure:

   • Plan column structure (2, 3, or 4 columns)
   • Map content flow (typically left-to-right, top-to-bottom)
   • Allocate space for title (10-15%), content (70-80%), footer (5-10%)

3. Set typography:

   • Configure font sizes for different hierarchy levels
   • Ensure minimum 24pt body text
   • Test readability from 4-6 feet distance

Stage 4: Content Integration

1. Create poster header:

   • Title (concise, descriptive, 10-15 words)
   • Authors and affiliations
   • Institution logos (high-resolution)
   • Conference logo if required

2. Integrate AI-generated figures:

   • Add all figures from Stage 2 to appropriate sections
   • Use \includegraphics with proper sizing
   • Ensure figures dominate each section (visuals first, text second)
   • Center figures within blocks for visual impact

3. Add minimal supporting text:

   • Keep text minimal and scannable (300-800 words total)
   • Use bullet points, not paragraphs
