Determining epub compiled size for Amazon paperback version

I recently created an epub version for an author. After much searching and trial and error, I finally got the compiling of the epub and Mobi down pat! Now, she is asking for the size used to compile to epub so she can match it on Amazon for her paperback set-up. I have no idea what she is looking for and where to find that information as the compiling is mostly automated through the process.

Please forgive my ignorance! :slight_smile: Can anyone help?!

This information doesn’t exist. Epubs don’t have “pages,” nor do they have “page size,” as the reader software determines the display font and font size.

She should choose a font and page size that she believes will be aesthetically pleasing to the majority of her readers.


That would explain why I could not find it despite my scouring! Thank you!!!
