There are two ways to change the font type and size to adapt your books to suit you.
Changing the font size across all titles
One is using the “Reader Settings” tab in the top navigation bar within Account settings.
This option allows you to change the font type for all the titles you have access to*. Font type changes are saved in your settings and will be kept even if you log out. Text size changes are not retained.
*Please note that it is not possible to change the text settings for some titles or sections of titles as these have been fixed to keep the appearance of the title.
Changing the font size of a specific title
The other way is using the Reader Settings option at the bottom of the page. This is also the only way to change font size in the Cambridge Reader app.
Changing the font here only changes it for the title you are currently viewing.
If you are using the Cambridge Reader app you will also need to press the Sync button at the bottom of the page.
