Reply To: Epubs optimized for specific devices

Hi David,

I may have spoken incorrectly about FXLs being optimized for a particular device. I went through my notes for Create A Fixed-Layout Epub With Indesign Cc and didn’t find anything on this.

However, her InDesign CC: EPUB Fundamentals, Chapter 7, the lesson on Previewing for the iBooks app, she talks about optimizing a reflowable for specific devices. This is what confuses me. If you’re making a reflowable epub with the intent of selling it on iBooks, for example, how would you know what dimensions to make this, if it’s intended to playback on multiple devices?

In the same manner, how does one know what dimensions to make a FXL, if it’s to be sold on a reseller’s website?
