Why Presentation Accessibility Matters

Accessible presentations are not just about compliance. They improve the experience for everyone:

• Audience reach: 1 in 6 people lives with a disability
• Legal compliance: ADA, Section 508, and EN 301 549 require accessible digital content
• Better design: Accessibility principles (high contrast, clear fonts, simple layouts) make slides better for all viewers
• Professional reputation: Inaccessible decks signal carelessness

For broader design best practices, see our 15 presentation design tips.

WCAG Guidelines for Presentations

The Web Content Accessibility Guidelines (WCAG) 2.1 apply to digital presentations. The four principles:

1. Perceivable

Content must be presentable in ways users can perceive.

What this means for slides:

• Provide alt text for all images and charts
• Use sufficient color contrast (4.5:1 for normal text, 3:1 for large text)
• Do not rely on color alone to convey information
• Provide captions or transcripts for audio/video content

2. Operable

Users must be able to navigate the interface.

What this means for slides:

• Ensure keyboard navigation works (Tab, Enter, arrow keys)
• Provide enough time to read each slide (or allow pausing)
• No flashing content more than 3 times per second (seizure risk)
• Provide skip links or navigation aids for long decks

3. Understandable

Content and operation must be understandable.

What this means for slides:

• Use plain language (aim for 8th-grade reading level for general audiences)
• Maintain consistent layout and formatting across slides
• Define acronyms on first use
• Use readable fonts (minimum 18pt for body text, 24pt for headers)

4. Robust

Content must work with assistive technologies.

What this means for slides:

• Use built-in slide templates (they include accessibility metadata)
• Tag PDF exports properly with headings and reading order
• Test with screen readers (NVDA, VoiceOver, JAWS)

Practical Accessibility Checklist

Use this checklist for every presentation:

Text and Fonts

• Minimum 18pt body text, 24pt headers
• Sans-serif fonts (Arial, Calibri, Helvetica)
• No more than 6 bullet points per slide
• Maximum 6 words per bullet point (the 6x6 rule)
• Left-aligned text (easier to read than justified)

Color and Contrast

• Color contrast ratio of at least 4.5:1
• Information does not depend on color alone (use text labels too)
• Avoid red-green combinations (common color blindness)
• Dark text on light background or vice versa

Images and Media

• Alt text for every image, chart, and diagram
• Descriptive alt text (not just "image" or "photo")
• Captions for all video content
• Transcript for audio content
• No flashing animations

Structure

• Use built-in slide layouts (not text boxes)
• Logical reading order (left to right, top to bottom)
• Consistent navigation across slides
• Slide titles on every slide
• Section breaks for long presentations

Delivery

• Speak all content on slides (do not assume everyone can read them)
• Describe charts and images verbally
• Share slides before the presentation (for screen reader users)
• Provide a printed handout in large print if requested

How to Make Accessible Slides in Popular Tools

PowerPoint Accessibility

PowerPoint has a built-in accessibility checker:

1. Go to Review > Check Accessibility
2. Fix all issues listed
3. Add alt text: Right-click image > Edit Alt Text
4. Use Accessibility Checker before every export

Reading order: Use the Reading Order Pane (Review > Check Accessibility > Reading Order Pane) to ensure screen readers read content in the correct sequence.

For PowerPoint alternatives, see our PowerPoint alternatives guide.

Google Slides Accessibility

Google Slides also has built-in accessibility tools:

1. Tools > Accessibility settings (enable screen reader support)
2. Add alt text: Right-click image > Alt text
3. Use Explore tool for image descriptions
4. Present with captions: Tools > Voice type speaker notes

For Google Slides alternatives, see our Google Slides alternatives guide.

AI-Generated Presentations

When using AI tools to generate presentations, accessibility depends on the tool:

• Ivern Slides: Generates clean layouts with good contrast. Add alt text manually after generation. See our AI slide generator guide.
• Canva: Has accessibility checker and alt text support. Templates vary in accessibility.
• Gamma: Generates visual presentations. Check contrast and add alt text manually.

Always run an accessibility check after AI generation. AI tools do not automatically produce WCAG-compliant output.

Tools for Checking Presentation Accessibility

---

Accessibility for Different Audiences

For Teachers and Educators

Students with IEPs (Individualized Education Programs) may require specific accommodations. Accessible presentations ensure compliance and help all students learn better. See our AI tools for teachers guide.

For Sales Teams

Procurement teams at large enterprises increasingly require accessibility documentation (VPAT/ACR) for any tool or content used internally. Accessible sales decks can be a competitive differentiator. See our AI presentations for sales teams guide.

For Conference Speakers

Major conferences (including tech conferences) increasingly require accessible slides. Submit slides with alt text, captions, and high contrast. See our conference presentation guide.

For Researchers and Academics

Academic presentations at conferences must be accessible to comply with institutional policies. See our research presentation guide.

Common Accessibility Mistakes

1. Low Contrast Text

Gray text on a white background is nearly unreadable for low-vision users. Use a contrast checker before finalizing.

2. Missing Alt Text

"Image1.jpg" or "photo" is not alt text. Describe what the image shows: "Bar chart showing 40% revenue growth from 2024 to 2026."

3. Color-Only Information

A chart that uses only red and green lines is unreadable for color-blind users. Add patterns, labels, or different line styles.

4. Tiny Fonts

If you need to squint to read it from the back row, it is too small. Minimum 18pt for body, 24pt for headers.

5. Wall of Text

Slides packed with paragraphs are inaccessible to users with dyslexia or cognitive disabilities. Break content into short bullets.

For more common mistakes, see our presentation mistakes guide.
