It should not be considered 'normal' in a properly created ePub....but, it all depends on the settings of your pdf and what you have included in your ePub.

- have you subset the fonts so it only includes the sigil's needed?
- have you cleaned all the coding 'bloat' from your html pages?
- have you checked the filesize of your images; are they the proper format, dimensions, and had unnecessary exif data removed?

I would think the last bullet is your primary culprit...IIRC pdf will automatically condense the image???

I am currently working on an ePub with over 200 chapters (over 17 million characters) basic front-matter and back-matter, and it is only 2.5 mb....which I personally consider too large.
