Why is fixed layout ePub3 used?
Even though a fixed layout cannot adjust itself on different devices, it is still used by many authors and publishers. It is mostly because certain books are suitable for the fixed kind of layout. For example, we can say double-page spread magazines, comic books, children’s illustration book, cookbooks, and coffee table books consists of texts and images that need to be maintained in a certain flow. In case these books are designed in any other layout, then a simple alignment shift might make the pictures lose the charm and the content difficult to read.

Many authors use it when they want the text and images of their document to appear in a definitive way without changing the orientation. So, if you want that the look of your eBook is similar to that of your printed book, then it is best to choose the fixed layout ePub3 format.

Limitations of ePub3 fixed layout format
A few years ago, the format ePub2 did not support features like videos, slideshows, fixed layout, etc. Even with ePub3, it was really difficult to find tools for developing eBooks in that format. It resulted in spending more time dealing with HTML and CSS code rather than working on content and appeal. However, this issue came to an end with the release of iBooks Author by Apple. It was an ePub3 development platform that enabled users to avoid dealing with code and allowed them to use both flowing and fixed layouts in a single book. Besides, the enhancements further helped in overcoming compatibility issues, and it was easier to extend the platform beyond any capabilities.
A couple of years later, Adobe implemented a lot of changes in its InDesign product to better use the features of ePub3. Most of the technology they used was supplied by Apple under the license agreement. It helped InDesign to produce eBooks that supported audios, videos, slideshows, fixed layout, and a lot of other features. So, it means that ePub3 is a viable format now which can be used by publishers and writers outside the Apple environment along with tools like InDesign, Photoshop, Illustrator, etc. for developing high-quality eBooks.
Since a fixed layout ePub3 is set only for a particular size of display, an issue will arise if the eBook file was formatted for one screen ratio and is displayed on the device with different screen ratio. This makes for a few small issues if the ebook file was formatted for one screen ratio (e.g., 1280 x 800 pixels: 16:10), but is displayed on a device with a different screen ratio (e.g., 1024 x 768 pixels: 4:3). As both these screen ratios, as well a third one, are available on current Samsung devices (to name but one of many manufacturers), there is no easy way to get the fixed layout ebook to match the screen ratio of every device. By comparison, iPads have a screen ratio of 4:3, while iPhones have a screen ratio of 16:9.
ePub3 readers keep the ratio of the ebook displayed in the same ratio at which it was designed, and all blank space to fill the screen if there is a need. In most cases, they will fit the book to the largest possible dimension of the screen, allowing the best possible reading display.
If the book is displayed text with squashed up together, the reader may be ignoring the fonts embedded in the ePub3 file, and is using default system fonts. Some readers allow the user to switch to the embedded fonts, but others do not. Some readers clearly do not use the embedded fonts, and so make the display pretty awful. The embedded fonts were used to ensure that the ebook could be read clearly as designed, so changing the fonts necessarily lowers the readability. If you see this kind of problem, try a different reader.
There is a very large number of ebook readers out there. They come in a wide range of capabilities, ease of use and cost. Many readers are free. A subset of the readers can handle ePub formats, and a subset of those can handle ePub3. A subset of those readers can handle fixed layout ePub3 ebooks, and a subset of those can handle ePub3 FXL (fixed layout) elegantly and reliably. Just because a reader says that it will display ePub3 files, it doesn't mean it will do it well, nor that it will display an ePub FXL file in a way that makes it readable. If you get huge text on screen, it generally means the reader won't handle ePub3 FXL.
If your reader doesn't display the book properly, get another. There are readers that will work well on all platforms tested, using our books, so there is always a reader. And we tested only readers that are free.
To categorized the various readers we tested, they are grouped by the operating system used in the device. We did test the book on various readers on different Apple platforms, and the book displays well there, so it can be used across very many platforms. However, if you will be using the book exclusively on Apple platforms, we strongly advise you to use the iBooks version, as it has both a smaller file size and is slightly more capable that the ePub3 version.
