Change Text Size with Zoom

To change the zoom in most browsers, press the following two keys at the same time:

  • In Windows, Linux, and Chrome OS:
    • To zoom bigger: "Ctrl" and "+" keys
    • To zoom smaller: "Ctrl" and "-" keys

    • To zoom bigger: "⌘" and "+" keys
    • To zoom smaller: "⌘" and "-" keys

Browsers provide specific guidance on different ways to change the page zoom or text-only zoom:

Other Text and Color Changes

Some browsers provide the functionality to set different aspects of font and colour in the default view.

Other text and colour settings are available in Reader View.

Reader View

Most browsers offer a “Reader View” or “Reading View” that shows just the main content; it gets rid of navigation, ads, etc. Some browsers let you set the text font, text size, text colour, background colour, and line spacing in Reader View.

Advanced Options

There are many browser extensions and add-ons that provide additional control over how the browser displays text and other content.

While most browsers no long support user style sheets, extensions provide similar advanced user control. For example, the Stylus extension is available for several major browsers.
