How to Make a Presentation Deck Accessible
Quick answer
An accessible deck is one that any audience member can follow, including people using a screen reader or with low vision, and the changes that make it accessible make it clearer for everyone. The four high-impact moves are checking contrast, keeping text large enough, establishing a logical reading order, and writing alt text for the meaningful images. Don't rely on color alone to carry meaning, and avoid putting everything in an image that a screen reader can't parse. Most of the work is a review pass rather than a redesign; running the checks slide by slide catches the failures before you present.
Contrast
Text needs a clear contrast against its background, especially for projected rooms where the washout is worse than on your screen. Check the body text and the labels, not just the big headlines.
Font size and layout
Small text is the fastest way to lose part of the room. Keep type large, limit the amount per slide, and give the content room; cramped slides hurt both readability and the screen-reader order.
The key checks
| Area | Rule |
|---|---|
| Contrast | Clear text-to-background difference |
| Font size | Large, readable from the back |
| Color | Never the only signal of meaning |
| Reading order | Logical, matches the visual flow |
| Images | Alt text for meaningful ones |
| Text | Actual text, not baked into images |
Reading order
A screen reader reads elements in the order they were added, which is not always the visual order. Set the sequence so the title comes first, then the content, and decorative elements are skipped.
Alt text
Describe what the image communicates in context, not just what it is. A chart needs its takeaway in the alt text; decorative graphics can be marked as such so they don't clutter the reading.
Don't rely on color alone
If a red and green label is the only difference between two states, add an icon or a word so the meaning survives without color. The same applies to links and emphasis.
The review process
- Walk the slides in order as a screen reader would.
- Check contrast and font size on every slide.
- Add alt text and confirm color isn't the only signal.
- Make sure text is real, not baked into an image.
- Present once to catch anything the checks missed.
The broader benefit
Captions, clear structure, and a single clear point per slide help the whole audience, not only those using assistive technology. Neatico can render the slides with real text and structured layouts, which makes the accessibility pass a review rather than a rebuild.
The bottom line
Accessibility is a set of concrete checks, not an extra feature. Verify contrast, keep text large, set a logical reading order, and write alt text, while never using color alone to carry meaning. The same changes make the deck clearer for everyone in the room, including on a washed-out projector. Run the pass slide by slide before presenting; when each slide can be followed by any audience member, the deck is accessible, and it is also simply better designed.
