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: Preventing Content Overflow

⚠️ POSTERS MUST NOT HAVE TEXT OR CONTENT CUT OFF AT EDGES.

Common Overflow Problems:

1. Title/footer text extending beyond page boundaries
2. Too many sections crammed into available space
3. Figures placed too close to edges
4. Text blocks exceeding column widths

Prevention Rules:

1. Limit Content Sections (MAXIMUM 5-6 sections for A0):

✅ GOOD - 5 sections with room to breathe:
   - Title/Header
   - Introduction/Problem
   - Methods
   - Results (1-2 key findings)
   - Conclusions

❌ BAD - 8+ sections crammed together:
   - Overview, Introduction, Background, Methods, 
   - Results 1, Results 2, Discussion, Conclusions, Future Work

2. Set Safe Margins in LaTeX:

% tikzposter - add generous margins
\documentclass[25pt, a0paper, portrait, margin=25mm]{tikzposter}

% baposter - ensure content doesn't touch edges
\begin{poster}{
  columns=3,
  colspacing=2em,           % Space between columns
  headerheight=0.1\textheight,  % Smaller header
  % Leave space at bottom
}

3. Figure Sizing - Never 100% Width:

% Leave margins around figures
\includegraphics[width=0.85\linewidth]{figure.png}  % NOT 1.0\linewidth

4. Check for Overflow Before Printing:

# Compile and check PDF at 100% zoom
pdflatex poster.tex

# Look for:
# - Text cut off at any edge
# - Content touching page boundaries  
# - Overfull hbox warnings in .log file
grep -i "overfull" poster.log

5. Word Count Limits:

• A0 poster: 300-800 words MAXIMUM
• Per section: 50-100 words maximum
• If you have more content: Cut it or make a handout

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.

MANDATORY prompt requirements for EVERY poster graphic:

POSTER FORMAT REQUIREMENTS (STRICTLY ENFORCE):
- ABSOLUTE MAXIMUM 3-4 elements per graphic (3 is ideal)
- ABSOLUTE MAXIMUM 10 words total in the entire graphic
- NO complex workflows with 5+ steps (split into 2-3 simple graphics instead)
- NO multi-level nested diagrams (flatten to single level)
- NO case studies with multiple sub-sections (one key point per case)
- ALL text GIANT BOLD (80pt+ for labels, 120pt+ for key numbers)
- High contrast ONLY (dark on white OR white on dark, NO gradients with text)
- MANDATORY 50% white space minimum (half the graphic should be empty)
- Thick lines only (5px+ minimum), large icons (200px+ minimum)
- ONE SINGLE MESSAGE per graphic (not 3 related messages)

⚠️ BEFORE GENERATING: Review your prompt and count elements

• If your description has 5+ items → STOP. Split into multiple graphics
• If your workflow has 5+ stages → STOP. Show only 3-4 high-level steps
• If your comparison has 4+ methods → STOP. Show only top 3 or Our vs Best Baseline

Content limits per graphic type (STRICT):

Example - WRONG (7-stage workflow - TOO COMPLEX):

# ❌ BAD - This creates tiny unreadable text like the drug discovery poster
python scripts/generate_schematic.py "Drug discovery workflow showing: Stage 1 Target Identification, Stage 2 Molecular Synthesis, Stage 3 Virtual Screening, Stage 4 AI Lead Optimization, Stage 5 Clinical Trial Design, Stage 6 FDA Approval. Include success metrics, timelines, and validation steps for each stage." -o figures/workflow.png
# Result: 7+ stages with tiny text, unreadable from 6 feet - POSTER FAILURE

Example - CORRECT (simplified to 3 key stages):

# ✅ GOOD - Same content, split into ONE simple high-level graphic
python scripts/generate_schematic.py "POSTER FORMAT for A0. ULTRA-SIMPLE 3-box workflow: 'DISCOVER' → 'VALIDATE' → 'APPROVE'. Each word in GIANT bold (120pt+). Thick arrows (10px). 60% white space. NO substeps, NO details. 3 words total. Readable from 10 feet." -o figures/workflow_overview.png
# Result: Clean, impactful, readable - can add detail graphics separately if needed

Example - WRONG (complex case studies with multiple sections):

# ❌ BAD - Creates cramped unreadable sections
python scripts/generate_schematic.py "Case studies: Insilico Medicine (drug candidate, discovery time, clinical trials), Recursion Pharma (platform, methodology, results), Exscientia (drug candidates, FDA status, timeline). Include company logos, metrics, and outcomes." -o figures/cases.png
# Result: 3 case studies with 4+ elements each = 12+ total elements, tiny text

Example - CORRECT (one case study, one key metric):

# ✅ GOOD - Show ONE case with ONE key number
python scripts/generate_schematic.py "POSTER FORMAT for A0. ONE case study card: Company logo (large), '18 MONTHS' in GIANT text (150pt), 'to discovery' below (60pt). 3 elements total: logo + number + caption. 50% white space. Readable from 10 feet." -o figures/case_single.png
# Result: Clear, readable, impactful. Make 3 separate graphics if you need 3 cases.

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
• "generous margins" and "no text near edges"

CRITICAL: AI-Generated Graphic Sizing

⚠️ Each AI-generated graphic should focus on ONE concept with MINIMAL content.

Problem: Generating complex diagrams with many elements leads to small text.

Solution: Generate SIMPLE graphics with FEW elements and LARGE text.

Example - WRONG (too complex, text will be small):

# BAD - too many elements in one graphic
python scripts/generate_schematic.py "Complete ML pipeline showing data collection, 
preprocessing with 5 steps, feature engineering with 8 techniques, model training 
with hyperparameter tuning, validation with cross-validation, and deployment with 
monitoring. Include all labels and descriptions." -o figures/pipeline.png

Example - CORRECT (simple, focused, large text):

# GOOD - split into multiple simple graphics with large text

# Graphic 1: High-level overview (3-4 elements max)
python scripts/generate_schematic.py "POSTER FORMAT for A0: Simple 4-step pipeline. 
Four large boxes: DATA → PROCESS → MODEL → RESULTS. 
GIANT labels (80pt+), thick arrows, lots of white space. 
Only 4 words total. Readable from 8 feet." -o figures/overview.png

# Graphic 2: Key result (1 metric highlighted)
python scripts/generate_schematic.py "POSTER FORMAT for A0: Single key metric display.
Giant '95%' text (150pt+) with 'ACCURACY' below (60pt+).
Checkmark icon. Minimal design, high contrast.
Readable from 10 feet." -o figures/accuracy.png

Rules for AI-generated poster graphics:

Split complex content into multiple simple graphics:

Instead of 1 complex diagram with 12 elements:
→ Create 3 simple diagrams with 4 elements each
→ Each graphic can have LARGER text
→ Arrange in poster with clear visual flow

Step 0: MANDATORY Pre-Generation Review (DO THIS FIRST)

⚠️ BEFORE generating ANY graphics, review your content plan:

For EACH planned graphic, ask these questions:

1. Element count: Can I describe this in 3-4 items or less?

   • ❌ NO → Simplify or split into multiple graphics
   • ✅ YES → Continue

2. Complexity check: Is this a multi-stage workflow (5+ steps) or nested diagram?

   • ❌ YES → Flatten to 3-4 high-level steps only
   • ✅ NO → Continue

3. Word count: Can I describe all text in 10 words or less?

   • ❌ NO → Cut text, use single-word labels
   • ✅ YES → Continue

4. Message clarity: Does this graphic convey ONE clear message?

   • ❌ NO → Split into multiple focused graphics
   • ✅ YES → Continue to generation

Common patterns that ALWAYS fail (reject these):

• "Show stages 1 through 7..." → Split into high-level overview (3 stages) + detail graphics
• "Multiple case studies..." → One case per graphic
• "Timeline from 2015 to 2024 with annual milestones..." → Show only 3-4 key years
• "Comparison of 6 methods..." → Show only top 3 or Our method vs Best baseline
• "Architecture with all layers and connections..." → High-level only (3-4 components)

Step 1: Plan Your Poster Elements

After passing the pre-generation review, identify visual elements needed:

1. Title Block - Stylized title with institutional branding (optional - can be LaTeX text)
2. Introduction Graphic - Conceptual overview (3 elements max)
3. Methods Diagram - High-level workflow (3-4 steps max)
4. Results Figures - Key findings (3 metrics max per figure, may need 2-3 separate figures)
5. Conclusion Graphic - Summary visual (3 takeaways max)
6. Supplementary Icons - Simple icons, QR codes, logos (minimal)

Step 2: Generate Each Element (After Pre-Generation Review)

⚠️ CRITICAL: Review Step 0 checklist before proceeding.

Use the appropriate tool for each element type:

For Schematics and Diagrams (scientific-schematics):

# Create figures directory
mkdir -p figures

# Drug discovery workflow - HIGH-LEVEL ONLY, 3 stages
# BAD: "Stage 1: Target ID, Stage 2: Molecular Synthesis, Stage 3: Virtual Screening, Stage 4: AI Lead Opt..."
# GOOD: Collapse to 3 mega-stages
python scripts/generate_schematic.py "POSTER FORMAT for A0. ULTRA-SIMPLE 3-box workflow: 'DISCOVER' (120pt bold) → 'VALIDATE' (120pt bold) → 'APPROVE' (120pt bold). Thick arrows (10px). 60% white space. ONLY these 3 words. NO substeps. Readable from 12 feet." -o figures/workflow_simple.png

# System architecture - MAXIMUM 3 components
python scripts/generate_schematic.py "POSTER FORMAT for A0. ULTRA-SIMPLE 3-component stack: 'DATA' box (120pt) → 'AI MODEL' box (120pt) → 'PREDICTION' box (120pt). Thick vertical arrows. 60% white space. 3 words only. Readable from 12 feet." -o figures/architecture.png

# Timeline - ONLY 3 key milestones (not year-by-year)
# BAD: "2018, 2019, 2020, 2021, 2022, 2023, 2024 with events"
# GOOD: Only 3 breakthrough moments
python scripts/generate_schematic.py "POSTER FORMAT for A0. Timeline with ONLY 3 points: '2018' + icon, '2021' + icon, '2024' + icon. GIANT years (120pt). Large icons. 60% white space. NO connecting lines or details. Readable from 12 feet." -o figures/timeline.png

# Case study - ONE case, ONE key metric
# BAD: "3 case studies: Insilico (details), Recursion (details), Exscientia (details)"
# GOOD: ONE case with ONE number
python scripts/generate_schematic.py "POSTER FORMAT for A0. ONE case study: Large logo + '18 MONTHS' (150pt bold) + 'to discovery' (60pt). 3 elements total. 60% white space. Readable from 12 feet." -o figures/case1.png

# If you need 3 cases → make 3 separate simple graphics (not one complex graphic)

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 2b: MANDATORY Post-Generation Review (Before Assembly)

⚠️ CRITICAL: Review EVERY generated graphic before adding to poster.

For each generated figure, open at 25% zoom and check:

1. ✅ PASS criteria (all must be true):

   • Can read ALL text clearly at 25% zoom
   • Count elements: 3-4 or fewer
   • White space: 50%+ of image is empty
   • Simple enough to understand in 2 seconds
   • NOT a complex workflow with 5+ stages
   • NOT multiple nested sections

2. ❌ FAIL criteria (regenerate if ANY are true):

   • Text is small or hard to read at 25% zoom → REGENERATE with "150pt+" fonts
   • More than 4 elements → REGENERATE with "ONLY 3 elements"
   • Less than 50% white space → REGENERATE with "60% white space"
   • Complex multi-stage workflow → SPLIT into 2-3 simple graphics
   • Multiple case studies cramped together → SPLIT into separate graphics
   • Takes more than 3 seconds to understand → SIMPLIFY and regenerate

Common failures and fixes:

• "7-stage workflow with tiny text" → Regenerate as "3 high-level stages only"
• "3 case studies in one graphic" → Generate 3 separate simple graphics
• "Timeline with 8 years" → Regenerate with "ONLY 3 key milestones"
• "Comparison of 5 methods" → Regenerate with "ONLY Our method vs Best baseline (2 bars)"

DO NOT PROCEED to assembly if ANY graphic fails the checks above.

Step 3: Assemble in LaTeX Template

After all figures pass the post-generation review, include them 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

Full workflow with ALL quality checks:

# STEP 0: Pre-Generation Review (MANDATORY)
# Content plan: Drug discovery poster
# - Workflow: 7 stages → ❌ TOO MANY → Reduce to 3 mega-stages ✅
# - 3 case studies → ❌ TOO MANY → One case per graphic (make 3 graphics) ✅
# - Timeline 2018-2024 → ❌ TOO DETAILED → Only 3 key years ✅

# STEP 1: Create figures directory
mkdir -p figures

# STEP 2: Generate ULTRA-SIMPLE graphics with strict limits

# Workflow - HIGH-LEVEL ONLY (collapsed from 7 stages to 3)
python scripts/generate_schematic.py "POSTER FORMAT for A0. ULTRA-SIMPLE 3-box workflow: 'DISCOVER' → 'VALIDATE' → 'APPROVE'. Each word 120pt+ bold. Thick arrows (10px). 60% white space. ONLY 3 words total. Readable from 12 feet." -o figures/workflow.png

# Case study 1 - ONE case, ONE metric (will make 3 separate graphics)
python scripts/generate_schematic.py "POSTER FORMAT for A0. ONE case: Company logo + '18 MONTHS' (150pt bold) + 'to drug discovery' (60pt). 3 elements only. 60% white space. Readable from 12 feet." -o figures/case1.png

python scripts/generate_schematic.py "POSTER FORMAT for A0. ONE case: Company logo + '95% SUCCESS' (150pt bold) + 'in trials' (60pt). 3 elements only. 60% white space." -o figures/case2.png

python scripts/generate_schematic.py "POSTER FORMAT for A0. ONE case: Company logo + 'FDA APPROVED' (150pt bold) + '2024' (60pt). 3 elements only. 60% white space." -o figures/case3.png

# Timeline - ONLY 3 key years (not 7 years)
python scripts/generate_schematic.py "POSTER FORMAT for A0. ONLY 3 years: '2018' (150pt) + icon, '2021' (150pt) + icon, '2024' (150pt) + icon. Large icons. 60% white space. NO lines or details. Readable from 12 feet." -o figures/timeline.png

# Results - ONLY 2 bars (our method vs best baseline, not 5 methods)
python scripts/generate_schematic.py "POSTER FORMAT for A0. TWO bars only: 'BASELINE 70%' and 'OURS 95%' (highlighted). GIANT percentages (150pt) ON bars. NO axis, NO legend. 60% white space. Readable from 12 feet." -o figures/results.png

# STEP 2b: Post-Generation Review (MANDATORY)
# Open each figure at 25% zoom:
# ✅ workflow.png: 3 elements, text readable, 60% white - PASS
# ✅ case1.png: 3 elements, giant numbers, clean - PASS
# ✅ case2.png: 3 elements, giant numbers, clean - PASS  
# ✅ case3.png: 3 elements, giant numbers, clean - PASS
# ✅ timeline.png: 3 elements, readable, simple - PASS
# ✅ results.png: 2 bars, giant percentages, clear - PASS
# ALL PASS → Proceed to assembly

# STEP 3: Compile LaTeX poster
pdflatex poster.tex

# STEP 4: PDF Overflow Check (see Section 11)
grep "Overfull" poster.log
# Open at 100% and check all 4 edges

If ANY graphic fails Step 2b review:

• Too many elements → Regenerate with "ONLY 3 elements"
• Small text → Regenerate with "150pt+" or "GIANT BOLD (150pt+)"
• Cluttered → Regenerate with "60% white space" and "ULTRA-SIMPLE"
• Complex workflow → SPLIT into multiple simple 3-element graphics

Visual Element Guidelines

⚠️ CRITICAL: Each graphic must have ONE message and MAXIMUM 3-4 elements.

ABSOLUTE LIMITS - These are NOT guidelines, these are HARD LIMITS:

• MAXIMUM 3-4 elements per graphic (3 is ideal)
• MAXIMUM 10 words total per graphic
• MINIMUM 50% white space (60% is better)
• MINIMUM 120pt for key numbers/metrics
• MINIMUM 80pt for labels

For each poster section - STRICT requirements:

MANDATORY prompt elements (ALL required, NO exceptions):

1. "POSTER FORMAT for A0" - MUST be first
2. "ULTRA-SIMPLE" or "ONLY X elements" - content limit
3. "GIANT (120pt+)" or specific font sizes - readability
4. "60% white space" - mandatory breathing room
5. "readable from 10-12 feet" - viewing distance
6. Exact count of words/elements - "3 words total" or "ONLY 3 icons"

PATTERNS THAT ALWAYS FAIL (REJECT IMMEDIATELY):

• ❌ "7-stage drug discovery workflow" → Split to "3 mega-stages"
• ❌ "Timeline from 2015-2024 with annual updates" → "ONLY 3 key years"
• ❌ "3 case studies with details" → Make 3 separate simple graphics
• ❌ "Comparison of 5 methods with metrics" → "ONLY 2: ours vs best"
• ❌ "Complete architecture showing all layers" → "3 components only"
• ❌ "Show stages 1,2,3,4,5,6" → "3 high-level stages"

PATTERNS THAT WORK:

• ✅ "3 mega-stages collapsed from 7" → Proper simplification
• ✅ "ONE case with ONE metric" → Will make multiple if needed
• ✅ "ONLY 3 milestones" → Selective, focused
• ✅ "2 bars: ours vs baseline" → Direct comparison
• ✅ "3-component high-level view" → Appropriately simplified

\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)

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: OVERFLOW CHECK (CRITICAL) - DO THIS IMMEDIATELY AFTER COMPILATION

⚠️ THIS IS THE #1 CAUSE OF POSTER FAILURES. Check BEFORE proceeding.

Step 2a: Check LaTeX Log File

# Check for overflow warnings (these are ERRORS, not suggestions)
grep -i "overfull\|underfull\|badbox" poster.log

# ANY "Overfull" warning = content is cut off or extending beyond boundaries
# FIX ALL OF THESE before proceeding

Common overflow warnings and what they mean:

• Overfull \hbox (15.2pt too wide) → Text or graphic is 15.2pt wider than column
• Overfull \vbox (23.5pt too high) → Content is 23.5pt taller than available space
• Badbox → LaTeX struggling to fit content within boundaries

Step 2b: Visual Edge Inspection (100% zoom in PDF viewer)

Check ALL FOUR EDGES systematically:

1. TOP EDGE:

   • Title completely visible (not cut off)
   • Author names fully visible
   • No graphics touching top margin
   • Header content within safe zone

2. BOTTOM EDGE:

   • References fully visible (not cut off)
   • Acknowledgments complete
   • Contact info readable
   • No graphics cut off at bottom

3. LEFT EDGE:

   • No text touching left margin
   • All bullet points fully visible
   • Graphics have left margin (not bleeding off)
   • Column content within bounds

4. RIGHT EDGE:

   • No text extending beyond right margin
   • Graphics not cut off on right
   • Column content stays within bounds
   • QR codes fully visible

5. BETWEEN COLUMNS:

   • Content stays within individual columns
   • No text bleeding into adjacent columns
   • Figures respect column boundaries

If ANY check fails, you have overflow. FIX IMMEDIATELY before continuing:

Fix hierarchy (try in order):

1. Check AI-generated graphics first:

   • Are they too complex (5+ elements)? → Regenerate simpler
   • Do they have tiny text? → Regenerate with "150pt+" fonts
   • Are there too many? → Reduce number of figures

2. Reduce sections:

   • More than 5-6 sections? → Combine or remove
   • Example: Merge "Discussion" into "Conclusions"

3. Cut text content:

   • More than 800 words total? → Cut to 300-500
   • More than 100 words per section? → Cut to 50-80

4. Adjust figure sizing:

   • Using width=\linewidth? → Change to width=0.85\linewidth
   • Using width=1.0\columnwidth? → Change to width=0.9\columnwidth

5. Increase margins (last resort):

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

DO NOT proceed to Step 3 if ANY overflow exists.

Step 3: 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 (7
