Here's how to magnify the text within a title on Epic from different devices:
iOS & Android: While you are reading a book, simply use the pinch gesture to zoom in and out.
Epic Website: With a book open, click the icon next to the progress bar below the book.
To turn the pages while zoomed in, click or tap the edge of the page like normal.
Please note: Zooming in does not increase the resolution of images/text. We try to make sure we have the highest resolutions available possible, but there are times when doing this can cause the images/text to become blurry while zoomed in.
