Increasing text size

Some users might find screen text easier to read by increasing the size at which text is displayed. To do this you should simply adjust your browser's settings.

If you use Microsoft Internet Explorer, go to the View menu, select Text Size and then either Larger or Largest.

If you use Netscape Navigator, go to the View menu and choose Increase Font until the text is the size you require.

If you use Firefox, go to the 'View menu', select 'Text Size' and then select 'Increase'. You can have the same effect by using the keyboard and press the keys 'Ctrl' and '+' at the same time.

External links

All external links on this website open in a new browser window (indicated by 'tool tip/alternative' text).

Downloading documents

Documents on this website are provided in a variety of formats. The most common are Adobe Acrobat PDF (PDF), Microsoft Word (MS Word) and Rich Text Format ( RTF). Most computers already have the software to open these document formats.

Adobe Acrobat support

PDF file standards have improved over the years and have become more accessible. However you may come across earlier versions of PDF files on our site which are not so accessible.

Also, Adobe Acrobat Reader version 6 and above has incorporated accessibility features into vstandard readers. For example, users can hear a PDF document read aloud, or scroll a PDF document automatically. The read aloud feature can also translate the document into a range of European languages. You can access these features in the Edit Preferences menu.

If you use screen reader software (for example an audio-enabled web browser) which is not compatible with Adobe Reader, Adobe provide a free online tool which converts the content of PDF files to a format which can be understood by most screen reader applications.

Adobe online conversion tool

You can configure your web browser to open PDF files either within the browser window or in a separate Adobe Acrobat window. There are detailed instructions on the Acrobat website on how to do so for different browsers.

File sizes

We also endeavour to ensure that the size of "downloadable" documents, such as Word and Adobe Acrobat PDFs, are no more than 500kb. Documents over this size are clearly indicated.


All images on this site include descriptive ALT (alternative text) attributes. Those that are purely decorative graphics or used for layout include null ALT attributes.
