Presentations are a part of everyday life, whether it’s a school project, a webinar, or a meeting at work.
Most presentations are built around visuals: charts, images, color‑coded data, and quick bullet points meant to be understood at a glance.
For some people, that works.
But for someone who is blind or low vision, that same information can quickly become inaccessible because it isn’t shared in a way they can use.
Making presentations accessible makes sure everyone can access the information they need.
How to Make Presentations Accessible
Remember Contrast
Low contrast can make text difficult to read, especially when viewed from a distance or on smaller screens.
Using high‑contrast color combinations, like dark text on a light background, makes content easier to read.
Use Descriptive Slide Titles
Titles shouldn’t be generic like “Slide 1” or “Overview.” Instead, they should tell the reader what the slide is actually about.
For example, a title like “Quarterly Revenue Growth” provides context and helps users navigate more easily.
If multiple slides cover the same topic, adding “(continued)” to the title helps make it clear to the audience.
Good titles both organize your presentation and guide people through it.
Keep It Simple
Any visuals added, such as graphs, tables, and more, should be kept as simple as possible.
Keep text to a minimum, and be sure to make fonts at least 24 points and Sans Serif, so that it is easy to read.
Don’t Rely on Visuals Alone
If a chart, graph, or image is important, don’t just say “as you can see here.” It assumes everyone can see it the same way.
Instead, describe what matters:
What is the trend? Is there any information that stands out? What should the audience take away?
This doesn’t mean reading every detail aloud.
It means making sure the meaning behind the visual is clear.
Use Alt-Text
Alt-Text is an important tool when adding any visuals to a presentation. Add clear descriptions of all visuals so that users with screen readers understand what the visual is.
Keep Slide Content Structured
Screen readers rely on structure to interpret slides correctly.
That means:
- Keeping text in a logical reading order
- Using simple layouts instead of overly complex designs
- Avoiding overlapping text boxes or scattered elements
When slides are well‑structured, they’re easier for everyone to follow.
Share Materials in Advance
Providing slides before a presentation gives people time to review content using assistive tools.
It also allows for better preparation and engagement during the presentation itself.
Why This Matters
Accessible presentations do more than share information.
They make participation possible.
At The Lighthouse of Houston, we know how access shapes opportunity. When people who are blind or low vision can fully engage with information, they’re not just included. They’re able to contribute, lead, and succeed.
That’s what it means to empower people to realize their full potential.
And it’s one of the many ways we move closer to a world where people live without limits.
