What is a Scientific Infographic?
A scientific infographic is a visual representation of scientific information, data, or concepts designed to communicate complex ideas quickly and clearly. Unlike general infographics used in marketing, scientific infographics prioritize:
- Accuracy: Every data point, statistic, and claim must be verifiable
- Clarity: Complex concepts must remain scientifically accurate while being accessible
- Credibility: Sources must be cited; claims must be supported
- Objectivity: Visual representations must not mislead or exaggerate
Scientific Infographics vs. General Infographics
| Aspect | Scientific Infographic | General Infographic |
|---|---|---|
| Primary Goal | Accurate communication | Engagement/marketing |
| Data Standards | Must cite sources | Often simplified |
| Audience | Researchers, students, educated public | General consumers |
| Design Approach | Clarity over flash | Visual impact first |
| Fact-checking | Essential | Variable |
| Complexity | Can include technical details | Usually simplified |
Common Uses for Scientific Infographics
1. Academic Posters
Conference posters are perhaps the most traditional use of scientific infographics. They condense months or years of research into a single visual narrative.
For detailed poster guidance, see our Scientific Poster Examples guide.
2. Social Media Science Communication
Platforms like Twitter/X, Instagram, and LinkedIn have become vital channels for sharing research. Infographics designed for social media must:
- Work at small sizes (mobile-first design)
- Grab attention in crowded feeds
- Communicate one key message quickly
- Include handles/links for attribution
3. Educational Materials
Teachers and professors use infographics to:
- Explain complex processes (photosynthesis, cellular division)

Design Principles for Scientific Infographics
1. Accuracy First
Never sacrifice accuracy for visual appeal. Every element must be:
- Factually correct: Verify all data and claims
- Properly sourced: Include citations or references
- Proportionally accurate: Bar charts and pie charts must reflect real ratios
- Up-to-date: Use the most current data available
2. Clear Visual Hierarchy
Guide viewers through your content with intentional design:
- Primary information: Largest, most prominent
- Secondary information: Supporting details, smaller
- Tertiary information: Sources, credits, fine print
Use size, color, and position to establish hierarchy.
3. Strategic Color Use
Colors in scientific infographics should:
- Aid comprehension: Use color to group related items
- Ensure accessibility: Consider colorblind viewers
- Maintain professionalism: Avoid garish or distracting palettes
- Be consistent: Same colors should mean the same things throughout
For science-appropriate palettes, see our Scientific Color Palette Guide.
4. Readable Typography
Text in infographics must be legible at the intended viewing size:
- Sans-serif fonts for most text (Arial, Helvetica, Open Sans)
- Adequate size: Minimum 12pt for print, 16px for digital
- High contrast: Dark text on light backgrounds (or vice versa)
- Limited font families: 2-3 maximum
For detailed font guidance, check our Best Fonts for Scientific Posters.
5. Effective White Space
Resist the urge to fill every pixel:
- White space improves readability
- Groups related elements together
- Creates visual breathing room
- Makes key elements stand out
Rule of thumb: If it feels crowded, remove something.
Data Visualization Best Practices
Data visualization is often the heart of scientific infographics. Get it right:
Choose the Right Chart Type
| Data Type | Best Chart Options |
|---|---|
| Comparison | Bar chart, grouped bar chart |
| Trend over time | Line chart, area chart |
| Part-to-whole | Pie chart (limited), stacked bar |
| Distribution | Histogram, box plot |
| Correlation | Scatter plot |
| Geographic | Map, choropleth |
Common Data Visualization Mistakes
1. Misleading axes
- Always start bar charts at zero
- Label axes clearly with units
- Don't truncate scales to exaggerate differences
2. Poor color choices
- Don't use red and green together (colorblind accessibility)
- Avoid rainbow color scales for sequential data
- Use consistent color meanings
3. Overcrowding
- Don't include every data point if it obscures the message
- Simplify where possible while maintaining accuracy
- Use annotations to highlight key findings
4. Missing context
- Include sample sizes
- Show error bars or confidence intervals when relevant
- Provide time frames and data sources
Annotation Strategies
Good annotations transform charts from confusing to clear:
- Call out key findings with arrows or highlighting
- Explain anomalies directly on the chart
- Provide context for unusual patterns
- Include "so what?" interpretation

Common Mistakes in Scientific Infographics
Mistake #1: Information Overload
Problem: Trying to include everything results in a cluttered, unreadable mess.
Fix: Focus on one main message. Create multiple infographics rather than one overcrowded one.
Mistake #2: Misleading Visualizations
Problem: Charts that distort data through improper scaling, 3D effects, or cherry-picked data.
Fix: Always use accurate proportions. Start bar charts at zero. Avoid 3D effects that distort perception.
Mistake #3: Missing Citations
Problem: Claims without sources undermine credibility.
Fix: Include a references section or footnotes. Use DOI links in digital versions.
Mistake #4: Poor Accessibility
Problem: Relying only on color to convey meaning excludes colorblind viewers.
Fix: Use patterns, labels, and shapes in addition to color. Test with colorblind simulators.
Mistake #5: Outdated Information
Problem: Using old data when newer data is available.
Fix: Always use the most recent reliable data. Include dates on data sources.
Mistake #6: Inconsistent Style
Problem: Mixing fonts, colors, and styles creates visual chaos.
Fix: Establish a style guide before starting. Use the same colors, fonts, and icon styles throughout.
Mistake #7: Ignoring the Audience
Problem: Using jargon with general audiences or oversimplifying for experts.
Fix: Know your audience and adjust complexity accordingly.

Frequently Asked Questions
What size should a scientific infographic be?
It depends on the use case. For social media, use platform-specific sizes (Instagram: 1080×1080px or 1080×1350px; Twitter: 1200×675px). For print posters, A0 (841×1189mm) or A1 (594×841mm) at 300 DPI. For web articles, aim for 800-1200px wide. Always design at the largest size you'll need and scale down.
How do I cite sources in an infographic?
Include a 'Sources' or 'References' section at the bottom of your infographic. For digital versions, use shortened URLs or DOI links. For print, list author, year, and publication. In data visualizations, add small superscript numbers linking to your reference list. Always include the date data was accessed for web sources.
How many colors should I use in a scientific infographic?
Limit your palette to 3-5 colors maximum. Use 1-2 primary colors for main elements, 1-2 secondary colors for supporting elements, and neutral colors (black, white, gray) for text and backgrounds. Ensure sufficient contrast for readability and consider colorblind accessibility.
How do I make my infographic accessible to colorblind viewers?
Never use color alone to convey meaning. Pair colors with patterns, labels, or shapes. Avoid red-green combinations. Use high contrast between elements. Test your design with colorblind simulation tools like Coblis or the Colorblinding Chrome extension. Consider using colorblind-friendly palettes like Okabe-Ito or viridis.
What's the difference between an infographic and a graphical abstract?
A graphical abstract is a specific type of infographic summarizing a single research paper, typically required by journals. It's usually a single image (often square) that captures the key finding and methodology of one study. General scientific infographics can cover broader topics, multiple studies, or educational concepts without being tied to a specific paper.
How long does it take to create a scientific infographic?
A simple infographic might take 2-4 hours for someone experienced. Complex infographics with custom illustrations and data visualizations can take 1-2 days or more. Factor in time for research, fact-checking, design iteration, and review. Using AI tools like ConceptViz can significantly speed up diagram creation.
Can I use icons and illustrations I find online?
Only if they're properly licensed. Use resources like The Noun Project, Flaticon, or Freepik that offer icons with clear licensing. Always check whether attribution is required. For scientific accuracy, be cautious of generic icons that might not accurately represent scientific concepts. When possible, create custom illustrations or use specialized scientific icon libraries.
Should I include my institution's logo?
It depends on the context. For conference posters and official institutional communications, yes—typically in a corner without dominating the design. For social media science communication or educational materials, it's optional. Check your institution's branding guidelines for logo usage requirements. Never distort the logo's proportions.
