Accessible Fonts

The PowerPoint Check Accessibility tool does not check for accessible font usage. Manually review content for readable font styles and accessible colour combinations to maximize the accessibility of your content.

Who benefits from accessible fonts

For people with low-vision or dyslexia, good font choices can make content easier to read. Accessible colour is essential for readers that are colour blind, but good colour practice benefits users printing in black and white, viewing in the sun with screen glare, using custom contrast settings, or experiencing other vision impairments.

The following animation shows what dyslexia may look like to some individuals. Accessible font choices can minimize the effect.

How to fix it

As the Check Accessibility tool does not examine fonts manual checks are required.

Font Size

On the Home tab choose Font and Font size using the menus.

Ensure fonts are size 20-24 minimum (slide numbers and footnotes are exceptions but should be at least 12 point). Learn more about changing the font size in PowerPoint.

If you find increasing the font size makes a slide overcrowded, move some content to a new slide. Having some blank space on slides is an excellent design choice.

Consider your audience. If you wear glasses take them off and view your slides. If presenting in a lecture theatre view your presentation from the back of the room. If using a projector take note of how lighting or the sun could make your slides more difficult to see.

Font Style

Avoid overly decorative fonts and exaggerated serifs. Serifs—the small ticks and lines at the end of a character stroke—can bleed together for some readers, making it harder for them to differentiate between characters and read content. Prefer sans-serif (Aptos, Calibri, Franklin Gothic, Helvetica, Montserrat, Verdana) or simple serifs like Sitka, Times New Roman, or Cambria.

Font Colour

To change font colours, select the text and on the Home tab open the Font Color menu. Choose your desired colour.

While the Check Accessibility tool cannot analyze your colour choices everywhere, you may find it useful to review information about the Hard-to-read text contrast error.

How to prevent it next time

PowerPoint’s default font choices are accessible; however, some themes may not have accessible fonts. If you want to change the font for all of your slides, it’s best to create a PowerPoint theme to ensure custom font and style is populated on each slide you create.

  1. "Dyslexia, previously known as word blindness, is a learning disability ('learning difficulty' in the UK) that affects either reading or writing. Different people are affected to different degrees. Problems may include difficulties in spelling words, reading quickly, writing words, "sounding out" words in the head, pronouncing words when reading aloud and understanding what one reads. Often these difficulties are first noticed at school. The difficulties are involuntary, and people with this disorder have a normal desire to learn." Dyslexia - Wikipedia “The one argument for accessibility that doesn’t get made nearly often enough is how extraordinarily better it makes some people’s lives. How many opportunities do we have to dramatically improve people’s lives just by doing our job a little better?” Steve Krug, Don’t Make Me Think, Revisited
