Apologies if you came here expecting that I was a playground designer, although there are people who make accessible play areas!

There is no perfect way to make things 100% accessible to everyone because people are different. I state that upfront as a reminder to myself as much as to anyone else that this work is not perfect, that it is messy, and that none of this should stop us from working to make things more accessible to more people right now.* I do not and I am not going to get everything right. I’m sure I’ve failed on a lot of these points in previous slide decks and I will continue to make mistakes. None of these tips are foolproof, and this list is not exhaustive. Perhaps you’ll read it and say you knew all these things already—and that you have some things to teach me! (Which would be great! Please do.) But, hey, maybe some of this will be new to some people. So, I will continue on with my imperfect notes on how I’ve been trying to make my slides more accessible.

Some of these things I learned from the speaker guide for NTEN’s Nonprofit Technology Conference, some from a class in graduate school on making information accessible (taught by the awesome Dr. Renee Hill!), some from independent learning about accessibility, and some things by trial and error.

The context of this post is creating slides that I’m preparing to present, such as for a conference talk, as opposed to other purposes. Although I may sometimes mention things related to presenting, the focus will be on the slides themselves. I most often use PowerPoint, so I mention some specific things in the version of the program I have, so if you have a more recent version or use something else for creating slides, those functions might be called something else or work a little differently.

Here are some things I’ve been learning and working at incorporating in my slides:

• Always check the template (and any other colored elements you are choosing) to ensure you have sufficient color contrast. Unfortunately, those default templates are not necessarily accessible – even when they are labeled as such. You’ll want to check things like the color contrast for people who are colorblind or have low vision. If you like to create your own templates, start with a color palette that has sufficient contrast. Of note, color contrast is not only about the colors, but sometimes about the size and font weight. Black text on a white background will work at any legible size, but certain color combinations that are readable at font size 40 will not be readable by everyone at a font size 20. While it’s not perfect, if your combination doesn’t work if printed in grayscale, you should probably adjust the color palette.
• Make sure every slide has a title. Occasionally, I will not use the template title area, or because I am not using a template, it is unclear which text is the title of the slide. While it might be obvious to a sighted person, it’s important to make sure someone using a screen reader would be able to use titles to help navigate through the slides. In PowerPoint, if you turn on “Check accessibility,” an Accessibility tab will be added to the ribbon at the top. You use the button for setting the slide title to set a specific text box to be the slide title.
• Include an agenda and let people know what point in the presentation they’re at. This is more of a presentation tip, but it’s helpful to orient people to what’s going to be covered and to give people a sense of where they are in the agenda. This can be especially helpful for people with cognitive or learning disabilities, but it’s helpful to everyone. I usually include a slide with a numbered list of the topics or sections, and then each section starts with a section header slide that references the section number and where we are in the presentation. (If it’s hard for me to break it out this way, then it probably means the presentation needs some further organization.)

• Use a font size of at least 18, but preferably larger! Using a larger font size also prevents you from putting too much text per slide, as slide are intended to be presented. If you truly need to write that much, you are writing a report! Or at least an article or blog post. They’re fine formats, but they are formats that meant to be read at your own pace instead of at the speed at which someone is giving a presentation.
• IF YOU WRITE IN ALL CAPITALIZED LETTERS FOR VERY LONG PORTIONS OF TEXT, THIS IS VERY DIFFICULT FOR EVERYONE TO READ. That took you an extra moment to read and comprehend, didn’t it?
• Leave the bottom 20% of the slide blank so that captions won’t cover up any content. Occasionally you might be presenting within a platform where the captions are not on top of the slides, but if you’re not sure, the bottom is often where captions are placed on a screen. (Unsure if there will be captions? Ask! It doesn’t matter whether you personally need them. Other speakers and attendees might, and they shouldn’t have to ask.)
• Include alternative text for images, videos, diagrams, and other visual elements that are relevant. Avoid text in images; simply use the text. (This is inaccessible both to people using screen readers and to people using translation software or other text-based tools.) For videos, you’ll need to consider both captions and video descriptions (a description of what is happening visually) so that the content is accessible to audience members who are blind or D/deaf. You can mark decorative images as decorative and skip the alt text, although it’s worth asking the question of what those images are adding to your presentation.
• Plan to describe the images verbally if they’re relevant. Okay this isn’t about the slides, but during the presentation, make sure you verbally describe the visual elements that you created alternative text for. Or if you are demonstrating something live, then describe what you’re doing – like if you were on a cooking show.
  • Speaker descriptions: Some people say the speakers should describe themselves, and others say this isn’t really useful information. Within the blind community, there are a lot of differing opinions on speaker descriptions. Unless I’m asked to describe myself visually, I tend to use the guideline of whether it is relevant. If the topic is related to career development, then the fact that I am an Asian American woman in my mid-30s is relevant. If I am talking about working remotely, then it makes sense to reference my surroundings. If I am showing people how to create diagrams, then a description of my visual appearance and what sighted people can see in my background feels performative rather than adding anything to an understanding of the topic.
• Review the order of object order on your slides. If someone is using a device like a screen reader, you’ll want them to go through everything on your slides in the correct order. An easy way to test this is to use the Tab key to tab through each object (title, text box, image, etc.) on each slide. You can usually right click to move an object forward or backward. (Reading order starts in the back and moves forward to end in the front.)

My process for creating slides

Sometimes it’s difficult to take a collection of tips and figure out how to apply them in practice. My process for creating slides and presentations may be different from yours, but here’s a rough summary of my current process:

1. Draft learning objectives, usually as a document.
2. Use the learning objectives to draft an outline, usually in the same document.
3. Start a new slide file and pick a template.
4. Check that the template color contrast is sufficient. (Turn on accessibility checker to help me with this if it’s available.)
5. Edit the template if needed.
6. Start building out the content in the slides – usually putting the bullet points from the outline as the temporary slide titles.
7. Work on developing the text and the speaking points in whatever order I can get it to come out in. Usually I put in placeholders for visuals that I need, but also sometimes information that I need to go find. I typically turn off or ignore the accessibility checker during this part.
8. Lots of iterating, editing, filling in those placeholders, refining speaking points.
9. Once the visual elements are finalized, I write alternative text. (I usually turn the accessibility back on at this point because it helps me tick off images that need alt text.)
10. If I forgot to describe something in the speaking points, then I incorporate the description of visuals.
11. Review and address any other accessibility issues that come up – with the exception of slide order, which I leave until last in case I need to make other changes.
12. Go through the presentation as a whole, both the slides and practicing the speaking, to make sure everything works together as a whole (and within the allotted time).
13. Check the slide order by tabbing through each object on each slide and adjusting the object order as needed.
14. If there’s a method for making the slides available to attendees ahead of the presentation (so they can review as needed, at their own pace, using the appropriate tools, ahead of time), then I do that.

What else? I’m open to learning how to do things better! Email me and let me know if you learned anything new from this post, have suggestions, or what your process looks like for creating slides.

*While there’s no such thing as perfect accessibility, there is indeed possibility to do things that make the situation worse. For example, using an accessibility overlay on your website often makes a website less accessible than say, if you had forgotten to put alt text for images. (Okay, that’s not great, but at least it doesn’t break the other parts of your website.) Better to keep things simple, and to keep working at making your website more accessible.
