Most of the main desktop browsers include a feature to change the font size and other content on web pages to a level you feel comfortable with.
There are two ways you can increase font sizes:
- Magnification/zoom: This increases the size of all content on the page (such as text, images, embedded videos, and so on), not just the font size.
- Text-only resizing: Only the font is resized – other content (such as images, embedded videos, and so on) remains the same size.
Be aware that not all browsers or websites support text-only resizing and, where they do, you may occasionally notice that some text becomes obscured or bleeds over other content on the page, effectively making it unreadable. We therefore recommend using magnification/zoom where possible.
