Whether you are using a small screen such as a smartphone or tablet, or using a laptop with a high resolution, you may have difficulty in reading on-screen text. However your web browser has a number of in-built tools to help you.

How to Zoom in or out on a web page:

Most web browsers offer the functionality to zoom in and out of a web page, the most common methods of doing this are as follows:

On most Windows-based web browsers (Edge, Internet Explorer, Chrome, Firefox) you can zoom a web page in by pressing CTRL and plus (+) together and can zoom out using CTRL and minus (-).
If you later want to reset to the default you can press CTRL and 0.

On Safari for Macs you can zoom in using Command and plus (+) and also zoom out with Command and minus (-)

For the most common mobile operating systems (both Android and iOS) you should be able to zoom by pinching the screen, moving two fingers together to zoom in and two fingers apart to zoom out.

On Android, for websites which do not normally allow zooming you can go to the web browsers options (3 dots on the top right) > select Settings > Select Accessibility > Select “Force enable zoom” to allow zooming. In this menu you can also select a default Text scaling to change the font size on all websites without needing to adjust the zoom.

How to use your keyboard for navigating web pages

Most desktop web browsers provide functionality to browse websites without the use of the mouse, although the functionality may vary depending on the construction of the site you are visiting.

To scroll the content on the page you can use the UP and DOWN arrow keys to scroll the page up/down a few lines at a time. To scroll greater amounts you can use PAGE UP/PAGE DOWN to scroll a screen’s height at a time and the HOME/END to scroll to the top/bottom of the page.

To cycle through the content of the website you can press the TAB key, this should cycle through all the links/menu items/clickable elements on the page and then pressing ENTER should follow the link. Further to this functionality you can press SHIFT and TAB to go back to the previous selected item on the page.

Using the keyboard you can also switch between the address bar and the content on the page by pressing F6. This allows you to enter a URL/search to visit, press F6 to then focus on the web page, using the above directions for navigation and then press F6 again when you wish to enter an alternative URL/search.

High Contrast Mode

Both Windows and macOS offer a high contrast mode that inverts the colours to make content easier to read, although the interaction may differ on different web browsers and individual websites.

To enable High Contrast:

on a Windows PC – First Select the start menu > Control Panel or System (this will differ based on the version of windows) > Ease of Access > High Contrast. Here you will be presented with the options for high contrast mode. Alternatively you can enable or disable high contrast mode with the keyboard shortcut – Left Alt + Left Shift + Print Screen/PRTSCR

on a Mac – First Select Apple > System Preferences > Universal Access. Then select the “Seeing” pane and on this pane you have the option to reverse the colours to “white on black” as well as a slider to enhance the contrast.
