Introduction to Accessible Ebook Production – Reflowable Ebooks
Reflowable books are the most flexible types of EPUB, and they can incorporate many accessibility features that all readers can benefit from. This brief introduction to reflowable ebooks discusses the benefits of this format.
Before reading this, you might want to review:
You’ve decided to create an ebook that is as accessible as possible, and so you’d like it to be reflowable. When an ebook is reflowable, readers can customize how they view the text (the layout) in many ways, which gives them agency over their reading experience.
When an ebook is formatted with a reflowable layout, the contents of the page will automatically adjust both to the orientation of the device (i.e., whether it is being held landscape/lengthwise or portrait/widthwise) and to its screen size. If desired, readers can also enlarge the text size, change the colour of the text and/or the background, as well as adjust spatial elements such as margins, line spacing, and justification. For many readers, being able to make these types of adjustments is integral to their comfort reading, but it is especially important for those users who have print disabilities.
InDesign allows its users to easily export a book file as either a “fixed-layout” (see Next Steps for more details) or “reflowable” EPUB — you simply choose one or the other. If your book is not image heavy or doesn’t include a lot of text boxes, we recommend choosing reflowable in order to be accessible to the widest reading market. The ability to customize how an ebook displays makes the reading experience better for everyone.
