Posted on by Mary Gillen

Low-vision users, and a lot of people over 50, need to increase the browser default font size to make text easier to read.

If your web content font sizes are set in absolute units, such as pixels, the user will not be able to re-size the text.

Relative units like EM and percentages “stretch” according to the screen size and/or user’s preferred font size, and work on a large range of devices.

Using relative units helps satisfy the WCAG 2.1 Guideline 1.4.4 Resize text Level AA.

Need to convert pixels to EMs?
