Type Hierarchy and Sizing for Presentations
Typography hierarchy is the system that tells the audience's eyes where to look first, second, and third. Without it, every element on the slide fights for attention equally — and the audience reads nothing.
The Hierarchy Stack
A well-designed presentation uses 4–5 typographic levels:
| Level | Purpose | Size Range | Weight | Example |
|---|---|---|---|---|
| H1 | Slide title | 28–40pt | Bold/Semibold | "Q4 Revenue Beat Expectations" |
| H2 | Section header within a slide | 20–24pt | Semibold/Medium | "Regional Breakdown" |
| Body | Main content text | 16–18pt | Regular | "The West region contributed 42% of..." |
| Caption | Supporting text, labels | 12–14pt | Regular/Light | "Source: Internal sales data, 2024" |
| Micro | Footnotes, legal, metadata | 8–10pt | Light | "Confidential — not for distribution" |
Establishing Hierarchy
Size Contrast
The most important tool. Each level should be noticeably different from the next.
The squint test: If you squint at the slide from across the room, can you still tell the title from the body text? If not, increase the size difference.
Minimum ratio: Each level should be at least 1.2–1.5x the size below it. For example:
- Title: 36pt
- Subtitle: 24pt (1.5x ratio)
- Body: 16pt (1.5x ratio)
- Caption: 12pt (1.3x ratio)
Weight Contrast
Bold text draws the eye before regular text, even at the same size:
- Bold for titles and the single most important word or phrase on the slide
- Semibold or Medium for section headers and labels
- Regular for body text
- Light for captions and footnotes (use sparingly — light weights are hard to read on projectors)
Color Contrast
Use color saturation to reinforce the hierarchy:
- Titles: Full-color primary or accent
- Body text: Dark neutral (charcoal or navy)
- Captions and footnotes: Medium gray
- Highlighted text: Accent color within body copy (used sparingly)
Spatial Hierarchy
White space signals importance:
- More space above a title = more visual weight
- Line spacing (leading): 1.2–1.5x the font size for body text
- Paragraph spacing: Add space between paragraphs rather than indenting
- Margin space: Elements closer to the center of the slide feel more important
Sizing for Different Contexts
Large Venue / Conference
Multiply all sizes by 1.2–1.5x:
- Title: 40–48pt
- Body: 20–24pt
- Minimum readable: 16pt
Standard Meeting Room
The default ranges above work well:
- Title: 28–36pt
- Body: 16–18pt
- Minimum readable: 12pt
Virtual / Screen Share
Slightly larger than meeting room (screens are smaller than projected slides):
- Title: 32–40pt
- Body: 18–20pt
- Minimum readable: 14pt
Printed Handout
Standard document sizing applies:
- Title: 20–24pt
- Body: 11–12pt
- Minimum readable: 8pt
Rules for Readable Text
Maximum Characters Per Line
- 40–60 characters per line is optimal for body text
- Wider lines cause the eye to lose its place returning to the next line
- On a full-width slide, this means body text should not span the full width — constrain it to 60–70% of the slide, or use columns
Line Spacing
- 1.2x the font size for short text blocks and titles
- 1.4–1.5x for longer paragraphs and body text
- 2.0x for lists with bullet points (the space helps scanning)
Letter Spacing
- Default (0) for body text at standard sizes
- Slight positive tracking (+50–100) for all-caps text and small captions
- Never use negative tracking in presentations — it reduces legibility at a distance
Alignment
- Left-aligned for body text (easiest to read in Western languages)
- Center-aligned for titles and short phrases (1–2 lines maximum)
- Never justify body text in presentations — the uneven word spacing is visible on large screens
- Right-aligned only for specific design purposes (numbers in tables, labels in left-margin layouts)
Common Hierarchy Failures
Everything the Same Size
When title, body, and labels are all 16–18pt, nothing is more important than anything else. The audience's eyes wander randomly.
Fix: Create at least a 2x difference between the largest and smallest text.
Too Many Sizes
When every element has a unique size (14pt, 15pt, 16pt, 17pt, 18pt), the hierarchy becomes noise rather than signal.
Fix: Use exactly 4–5 sizes and be consistent throughout the deck.
Bold Overload
When everything is bold, nothing is emphasized. Bold loses its power when overused.
Fix: Reserve bold for titles and one key phrase per slide. Everything else in regular weight.
Common Mistakes
| Mistake | Fix |
|---|---|
| Body text below 14pt in presentations | Minimum 14pt for projected content; edit content to fit |
| No visible difference between title and body | Title should be at least 1.5x the body size |
| Centered body paragraphs | Left-align paragraphs; center only titles and short phrases |
| Five different font sizes on one slide | Limit to 3 sizes per slide, 4–5 across the deck |
| Light font weight on a projector | Avoid light/thin weights — they wash out on projection |
