If most of the text is too small to read, select the view menu of the browser, then set the text size to a larger setting.

Why do you have to do this?

This website is designed to follow the accessibility guidelines of the Royal National Institute for the Blind (RNIB). One way we do this is we set font sizes so that they can be reset by our users, as described above. This permits people who need larger print in order to read to set the size large enough for their needs. It also means that if the text size in the browser is set to "very small" then you will be unable to read the text.

Many website set their text sizes in ways that cannot be resized. On sites like this, if you need larger print in order to read, you are out of luck. On the other hand, if your sight is average, then even if your browser is set to display text as small as possible, you will not notice a problem.
