Presentation Design Principles: Create Slides That Enhance Your Message

Great presentation design doesn't distract from your message—it amplifies it. Whether you're creating a sales pitch, conference talk, or business update, understanding core design principles will help you create slides that engage, clarify, and persuade.

The impact of good design:

• Increases audience retention by 65%
• Makes complex information accessible
• Establishes credibility and professionalism
• Keeps attention focused on key messages

The cost of bad design:

• Confuses and overwhelms audiences
• Undermines your credibility
• Causes disengagement
• Obscures your message

Less is always more:

The rule: One idea per slide

Why it works:

• Reduces cognitive load
• Focuses attention
• Increases retention
• Prevents overwhelm

In practice:

• ❌ Slide with 10 bullet points
• ✅ Slide with 1 key message + supporting visual

Simplification techniques:

• Remove unnecessary text
• Use visuals instead of words
• Break complex slides into multiple simple ones
• Ask: "What can I remove?"

Guide the eye to what matters most:

Size matters:

• Larger elements draw attention first
• Use size to show importance
• Create clear focal points

Example hierarchy:

1. Headline (largest) - Main message
2. Supporting text (medium) - Key details
3. Source/notes (smallest) - Attribution

Contrast creates hierarchy:

• Bold vs. regular weight
• Color vs. grayscale
• Large vs. small
• Isolated vs. grouped

Maintain visual coherence:

Be consistent with:

• Font choices (2-3 maximum)
• Color palette (3-5 colors)
• Layout and spacing
• Image style and treatment

Why consistency matters:

• Creates professional appearance
• Reduces distraction
• Builds visual rhythm
• Strengthens brand

Use templates:

• Create master slides
• Define styles once
• Apply consistently
• Maintain throughout

Everything should line up:

Types of alignment:

• Left-aligned: Most readable for text
• Center-aligned: Good for titles and images
• Right-aligned: Rarely used, creates tension
• Justified: Avoid in presentations

The grid system:

• Use invisible grid for layout
• Align elements to grid lines
• Create visual order
• Maintain consistent spacing

PowerPoint/Keynote tools:

• Smart guides
• Align and distribute tools
• Snap to grid
• Ruler and guides

Make important elements stand out:

Types of contrast:

• Color: Dark vs. light
• Size: Large vs. small
• Weight: Bold vs. regular
• Space: Crowded vs. isolated

Contrast for readability:

• Dark text on light background
• Light text on dark background
• Avoid low-contrast combinations
• Test from distance

Contrast for emphasis:

• Highlight key words in color
• Make important numbers larger
• Isolate critical information
• Use white space strategically

Choose readable fonts:

Sans-serif fonts (best for presentations):

• Helvetica
• Arial
• Calibri
• Open Sans
• Montserrat

Why sans-serif:

• Cleaner at large sizes
• More readable from distance
• Modern and professional
• Works well on screens

Avoid:

• Decorative fonts (hard to read)
• Script fonts (too ornate)
• Too many different fonts
• Fonts that are too thin

Minimum sizes for readability:

• Titles: 36-44pt
• Body text: 24-32pt
• Captions: 18-20pt minimum

The 6-foot rule:

• Can you read it from 6 feet away?
• If not, make it bigger
• Test on actual screen/projector

Best practices:

Use hierarchy:

• Bold for emphasis
• Regular for body
• Avoid underline (looks like links)
• Use italics sparingly

Line spacing:

• 1.2-1.5x line height
• More space = easier reading
• Don't cram text together

Text length:

• Maximum 6 lines per slide
• Maximum 6 words per line
• Shorter is better
• Use visuals to replace text

Start with 3-5 colors:

Color roles:

1. Primary color: Brand or main theme (60%)
2. Secondary color: Supporting elements (30%)
3. Accent color: Highlights and emphasis (10%)
4. Neutral colors: Text and backgrounds (always)

Color combinations that work:

• Monochromatic: Shades of one color
• Analogous: Colors next to each other on wheel
• Complementary: Opposite colors (use carefully)
• Triadic: Three evenly-spaced colors

Tools for color selection:

• Adobe Color
• Coolors.co
• Canva Color Palette Generator
• Brand guidelines (if applicable)

Colors communicate meaning:

Blue:

• Trust, professionalism, stability
• Most popular business color
• Safe choice for corporate

Red:

• Energy, urgency, passion
• Grabs attention
• Use for emphasis, not backgrounds

Green:

• Growth, health, environment
• Calming and positive
• Good for sustainability topics

Orange:

• Creativity, enthusiasm, warmth
• Friendly and approachable
• Good for innovation themes

Purple:

• Luxury, creativity, wisdom
• Less common in business
• Stands out from competitors

Yellow:

• Optimism, energy, caution
• Hard to read as text
• Use as accent only

Gray:

• Neutral, professional, sophisticated
• Good for backgrounds
• Pairs well with any color

Ensure everyone can see your slides:

Contrast ratios:

• Minimum 4.5:1 for normal text
• Minimum 3:1 for large text
• Test with contrast checker tools

Color blindness considerations:

• Don't rely on color alone
• Use patterns or labels too
• Avoid red-green combinations
• Test with color blind simulator

Tools:

• WebAIM Contrast Checker
• Color Oracle (simulator)
• Stark (Figma plugin)

Divide slide into 9 equal parts:

• Place important elements at intersections
• Creates visual interest
• More dynamic than centering everything

Application:

• Position images at thirds
• Align text to grid lines
• Create asymmetric balance

Empty space is powerful:

Benefits:

• Focuses attention
• Creates breathing room
• Looks professional
• Reduces overwhelm

How to use:

• Don't fill every inch
• Let elements breathe
• Use margins generously
• Embrace emptiness

Example:

• ❌ Slide crammed with content
• ✅ One key message with lots of space around it

How eyes scan slides:

Z-Pattern (for image-heavy slides):

• Top left → Top right
• Diagonal to bottom left
• Bottom left → Bottom right

F-Pattern (for text-heavy slides):

• Top horizontal scan
• Down left side
• Second horizontal scan (shorter)

Design accordingly:

• Place important info in scan path
• Use patterns to guide attention
• Test with eye-tracking if possible

Use high-quality images:

Image sources:

• Unsplash (free, high-quality)
• Pexels (free stock photos)
• Shutterstock (paid, professional)
• Your own photography

Image best practices:

• Use full-bleed images (edge to edge)
• Ensure high resolution (at least 1920x1080)
• Avoid cheesy stock photos
• Use authentic, relevant images

Image treatment:

• Apply consistent filters
• Use overlays for text readability
• Crop strategically
• Maintain aspect ratios

Icons simplify concepts:

When to use icons:

• Represent categories or concepts
• Create visual lists
• Show processes or steps
• Replace bullet points

Icon sources:

• Noun Project
• Flaticon
• Font Awesome
• Icons8

Icon best practices:

• Keep same visual weight
• Use same color or monochrome
• Size appropriately

Data visualization principles:

Choose the right chart:

• Bar chart: Compare categories
• Line chart: Show trends over time
• Pie chart: Show parts of whole (use sparingly)
• Scatter plot: Show relationships

Simplify data:

• Show only relevant data
• Remove gridlines and clutter
• Use color to highlight key points
• Label directly on chart

Make it readable:

• Large, clear labels
• Minimal text
• High contrast
• Explain what it means

Use sparingly and purposefully:

When animations help:

• Reveal information progressively
• Show cause and effect
• Guide attention
• Demonstrate processes

When to avoid:

• Gratuitous effects
• Distracting movements
• Slow transitions
• Inconsistent animations

Best practices:

• Keep it simple (fade, appear)
• Use consistently
• Don't overdo it
• Test timing
