I’m in the process of trying to figure out the best app/device/format in which to read my collection of ebooks. Since most of my devices reside in the Apple ecosystem, I’ve tried giving Apple Books a shot. When reading on my iPhone, I prefer to use vertical scrolling rather than turning the page due to the aspect ratio of the device. I’ve noticed that some books have absurdly wide margins when viewed this way (see my attached screenshot for an example). I’ve found that converting the epub to epub (I know that sounds redundant), and using the tablet output profile, will fix this margins issue. Unfortunately, it tends to add other formatting issues in the process (such as chapter headings no longer looking correct or weird formatting for block indented text). I’ve also attached a screenshot showing what I mean by this.
I don’t really know enough about the structure of an epub file to know how to begin troubleshooting this issue. I’m hoping someone here could point me in the right direction on how to fix the original issue with wide margins without messing up the rest of the ebook in the process.
