Text Size in PowerPoint
Text in presentations must be large enough to read comfortably, whether viewing on a computer screen, projected on a wall, or viewed by audience members at the back of a room.
What This Means
Presentations are often viewed from a distance or on shared screens. Text that's too small becomes illegible, excluding users with low vision and making the presentation less effective for everyone.
Why It Matters
- Presentations are viewed from a distance unlike documents
- Projectors may reduce clarity, requiring larger text
- Users with low vision need adequate text size
- Readable text improves comprehension for all viewers
Common Violations
PPTX-09-001: Text Is Too Small to Read {#PPTX-09-001}
What's Wrong: Text on slides is too small to be comfortably read by audience members, especially those with visual impairments or sitting far from the screen.
Impact: Moderate - Content becomes difficult or impossible to read at typical viewing distances.
Minimum Size Recommendations:
- Slide titles: 28pt minimum (36-44pt recommended)
- Body text: 24pt minimum (28-32pt recommended)
- Chart labels: 18pt minimum
- Footnotes: 18pt minimum (avoid when possible)
How to Identify:
- View the presentation in Slide Show mode
- Step back from your monitor
- Check readability from across the room
- Use Reading View to simulate viewing experience
How to Fix:
- Select the text to resize
- Go to Home > Font Size
- Increase to recommended size
- Or use Format > Font for precise control
The "Back Row Test"
A simple test for readability:
- View your slide on a typical monitor
- Stand back 6-8 feet (2-2.5 meters)
- Can you read all text comfortably?
- If not, increase the size
This simulates viewing from the back of a presentation room.

Factors Affecting Readability
Room Size
- Large rooms need larger text
- Consider the farthest viewer
- Double text size for very large venues
Screen Size
- Small screens need relatively larger text
- Consider laptop viewing vs. projection
- Multi-screen setups may vary
Lighting
- Bright rooms reduce contrast
- Dim rooms may allow smaller text
- Design for typical conditions
Font Choice
- Sans-serif fonts are more readable (Arial, Calibri)
- Avoid decorative fonts for body text
- Bold adds visibility but uses more space
Strategies for More Content
If you have too much text:
Reduce Content
- Edit for brevity
- One idea per slide
- Move details to speaker notes
Use Multiple Slides
- Split content across slides
- Each slide focuses on one point
- Maintains readable text size
Simplify Design
- Remove unnecessary graphics
- Increase text area
- Use cleaner layouts
Provide Handouts
- Detail in printed materials
- Slides stay clean and readable
- Audience can review later
Font Recommendations
Best for Presentations:
- Arial - Clean, widely available
- Calibri - Modern, readable
- Verdana - Designed for screens
- Helvetica - Classic, professional
Avoid:
- Decorative fonts (Comic Sans for professional use)
- Serif fonts for body text (harder to read projected)
- Very thin or light weights
- All caps for body text
Checking Font Sizes
In Normal View:
- Select text
- Look at Font Size in Home tab
- Note sizes of different elements
Using Selection Pane:
- Home > Arrange > Selection Pane
- Click each text element
- Check font size in toolbar
Slide Master View:
- View > Slide Master
- Review placeholder text sizes
- Adjust master for consistent sizing
Template Considerations
Create Accessible Templates:
- Start with appropriate font sizes
- Set minimum sizes for each placeholder
- Test at presentation size
- Document size requirements
Review Existing Templates:
- Check default font sizes
- Modify if below minimums
- Test before important presentations
Best Practices
Do:
- Use 24pt minimum for body text
- Use 28pt+ for titles
- Test readability from a distance
- Consider your audience and venue
- Use sans-serif fonts
Don't:
- Shrink text to fit more content
- Use less than 18pt for any text
- Rely on "zoom" to read small text
- Use decorative fonts for body content
- Assume close viewing distance
