Making your web browser more accessible
The five most popular web browsers are Google Chrome, Firefox, Internet Explorer, Apple Safari and Opera in that order.
Basic zoom instructions
This method works on most commonly used web browsers:
Windows – From the keyboard, you can increase or decrease the zoom value in 10% increments. To zoom in, press Ctrl+(+). To zoom out, press Ctrl+(-). To restore the zoom to 100%, press Ctrl+0 (zero).
Mac – To zoom in, press Cmd+(+). To zoom out, press Cmd+(-). To restore the zoom to 100%, press Cmd+0 (zero).
Detailed zoom instructions
Below you will find a step-by-step guide to zooming in on websites in your browser. If you have also changed the settings in your operating system and find that this does not magnify the text enough to be useful, then it is worth investigating screen magnification software.
These instructions are for use with the latest browser versions, however they may also work with other versions of the same web browser.
In order to increase or decrease the zoom level of the currently displayed web page, you can use either the keyboard shortcuts (see table below) or access ‘Zoom->Larger/Normal/Smaller’ in the Chrome Page menu.
Page zoom level will be remembered for each unique domain, e.g. if you increase zoom for Google Search (https://www.google.com), zoom level will also be increased for Google Calendar (https://www.google.com/calendar). However, since Gmail (https://mail.google.com) is on a different domain, zoom level will remain unchanged in this example.
Ctrl++ Increase zoom level.
Ctrl+- Decrease zoom level.
Ctrl+0 Set zoom level to default level.

In addition, there are a variety of Chrome Extensions that can be used to modify various font properties:
- Optional font family and font size configuration

High Contrast and Custom Color Support

- Install a Chrome Extension which allows you to specify your own custom color combinations, for instance the Change Colors extension.
- Quick page action to apply/remove styling overrides on a per page, per domain or global basis (overriding Web page colors)
- Optional background, text, links and visited links color configuration
- Option for showing/hiding images
- Option for showing/hiding Flash objects
