Speaker’s guide: How to make your presentation more accessible

Illustration of a speaker presenting in front of an audience. On the screen behind her, a simple slide is shown with a bar chart and a pie chart in clear colours with good contrast.

If you want to ensure that as many people as possible can follow your presentation—both in the room and online—here are some simple recommendations that will make your presentation more accessible to everyone.

It's not about perfection, but about thinking a bit more broadly about how your content is communicated.


1) Use large fonts on your slides

Avoid small fonts. As a rule of thumb, body text should be at least about 24–28 pt, so it can also be read from the back row and on livestream.

A good tip is also to let the font size help you prioritize the content: If the text becomes too small to fit, it's often a sign that your slide contains too much information.

Large fonts therefore not only help with readability—they also force you to keep slides simpler and more focused. This almost always benefits your communication.


2) Ensure good contrast

Text color should have clear contrast with the background to make it easy to read.

For example, avoid:

  • 👎 Light gray text on white background
  • 👎 Yellow text on white background
  • 👎 Dark colors on dark background
  • 👎 Very light or pastel-colored text colors

Good contrast not only makes the text easier to read for people with reduced vision—it helps the entire audience.

When presentations are displayed via projector, the contrast can often become worse because projectors typically have lower brightness than computer screens. Text with weak contrast can therefore quickly become hard to read in the room for everyone.

Good contrast helps ensure your messages can be seen.


3) Don't use color alone to convey information

People with color blindness may have difficulty distinguishing between certain colors (e.g., red and green).

If colors are used in graphs or diagrams, combine them with:

  • Labels
  • Patterns
  • Symbols
  • Or clear explanations

The trick is quite simple: If your graphic still makes sense in a purely black-and-white version, it will almost always also work when colors are added. (If, that is, you use colors with good contrast—see point 2 about contrasts. 👆)


4) Briefly explain the key points in graphs and images

If you show graphs, diagrams, or complex illustrations, state the most important points out loud.

Example:

  • ✅ "In this graph, you can see that the proportion has increased from 20% to nearly 50% over the past five years."

Avoid:

  • 👎 "As you can see here, our sales have gone well this year." (What has gone well and how?)

This helps both people with visual impairments—and everyone else in the room—to understand what you want to emphasize. It also helps listeners who are multitasking, have gotten up from their computer for coffee, can't see certain parts of the screen, etc.

You don't need to explain all icons and images if they are solely decorative. Instead, consider whether they add meaning to your point. On the other hand, it can be nice to briefly describe images with more personal or poetic value—for example: "Here's a childhood photo of me on a blue bike."

The goal is for as many as possible to receive roughly the same message, without unnecessarily slowing down or burdening the presentation.


5) Also say what you are pointing to

If you point to something—either on a slide or in the room—remember that not everyone can see it.

For example, say:

  • ✅ "In the graph on the right, you can see …"
  • ✅ "You’ll find the toilets to the right of the stage."

Avoid:

  • 👎 "The toilets are over there."
  • 👎 "Follow the green signs to get to the cafeteria."

This helps both people with visual impairments, online participants, and possibly interpreters.


6) Consider videos

If you show video in your presentation:

  • Does the video have subtitlesif there is speech in it?
  • Does it contain important visual information with no speech?

If something important is only shown visually, a brief explanation can be a big help.

Ideally, a video should be described for the visually impaired (audio-described), if it cannot be understood by those who can't see it.

7) Speak at a natural pace

Clear speech and a natural pace help both the audience and any interpreters.

You don’t need to speak slowly or change your normal way of speaking. The most important thing is to avoid both speed-talking and an unnaturally slow pace. If the audience can keep up, interpreters usually can too.

Small pauses between key points can make the presentation easier to follow and give both the audience and interpreters a chance to keep up.


8) Consider sending material in advance

If the event has sign language interpretation or live captioning, it’s a great help if you can send in advance—and usually at least a week before—your:

  • slide drafts
  • outline
  • or just main talking points

This makes it easier for interpreters to prepare and is typically required for them to feel ready to handle the task. The interpreters will use the material to assess if there are specific terms or expressions they need to be prepared for.

If you start your preparation with an outline, you always have something ready for the interpreters in case your presentation is only finished at the last minute. An outline also helps you keep a good structure.


Bonus: Consider briefly describing yourself when you start

When you begin your presentation, it can help to briefly say:

  • your name
  • your role or organization
  • optionally, a brief description of how you look

Example:
"My name is Andrea Andersen, I work as a museum curator at the Danish Lighthouse Museum. I have short, light hair and am standing here in a dark blazer and glasses."

This can help participants who cannot see the stage clearly.

It’s also perfectly fine to sneak a bit of personality into your description. I once saw someone present their own portrait photo as: "He looks like he just had a lovely Christmas Eve."


Remember: Small things make a big difference

You don’t have to do everything perfectly.

Often, three small things make the biggest difference:

  • clear slides
  • explaining the key points in graphs
  • and saying what you are pointing to.
