Kindle Previewers versus the real devices

[astro123]

Looking at some test files on the Previewers (including 3) and then sending the file to the actual devices, the bullets are much smaller using the Previewers than they are on the devices, where they are normal size.

So, I guess the question is -- which in the end are more reliable when testing for the end product? And why is there a difference?

I know that Kindle PC as well as the KDP online upoad/viewer are browser dependent, so not necessarily what one would see on the mobile device(s).

thanks

Are you using the same fonts? Maybe your Previewer is using a different default font set.
If you specify named fonts, are they the same then?


Recently I found that using the Previewer to convert complex epubs to mobi, that the e-ink previews often crashed, the Fire preview always was fine.
So I finally got a real Paperwhite and tested the files on that; they worked fine, even the ones that crashed in the preview.

So I don't trust the Previewer much when it comes to previewing.
