Readability refers to how easily text can be read and understood by your intended audience. It combines clear language and accessible formatting so that students can engage with the content without unnecessary barriers.
When reviewing or developing readable content it is important to remember that students may open files on different devices which can impact readability. Without proper formatting, content may adjust to different sizes or spacing and impact how content is displayed when the file is opened.
Use sans-serif fonts (Arial, Calibri, Verdana) instead of stylized or serif fonts.
Stick with standard font sizes (10 - 12 point for body text, larger for headings).
Avoid decorative fonts or ALL CAPS for long passages.
