Overview

Users can easily change the font size in their web browser. They can either do this permanently within their browser preferences or do it on the fly using their browser’s zoom functionality.

All major desktop web browsers have built-in functionality that enables users to zoom in:

  • In Windows browsers: Ctrl and plus (+)
  • in Mac browsers: Command and plus (+)

To zoom out, use the same keystrokes with the minus key.

By default, browsers preserve the page proportions when users zoom in and out, so the content changes size but the layout does not change. However, this results in a need for horizontal scrolling which makes it difficult to read the page. Therefore, some users prefer to simply enlarge the text, not the entire page.

When users increase their browser’s default font size or enlarge text using their browser’s zoom functionality,  the page content should still be readable.
