Does your book look good in Kindle previewer? As you know, page count doesn't matter in ebooks because each reader can change font size and other appearance variables at will. What you are looking is probably "screen count" not pages. The Kindle previewer in lack of having an actual Kindle, is the best tool to preview your Kindle ebook.
The Kindle previewer allows you test in the different Kindle versions: Kindle Fire, Kindle Paperwhite, Kindle HD, etc. You just have to choose the version you want.
Thanks so much for your input.
Yes, it looks great in Kindle Fire, Kindle Fire HD, and Kindle Fire HD 8.9". The Paperwhite kind of breaks things up on some pages, forcing text onto the next page. The regular Kindle (which I guess is the old original Kindle), and Kindle DX look terrible. Both the Kindle for iPhone and iPad don't seem to recognize page breaks, and break things up. But the Fire, Fire HD, and Fire HD 8.9" look very good.
So I'm guessing from your response that once we finalize the books (it's in five languages), they'll work fine once uploaded to Amazon?
When you submit your Kindle book to Amazon, they will check it for any issues. If everything is OK, you still have a chance to review it one more time before it goes public. I have no experience with other languages. I'm about to publish one in Spanish, and plan to do it in a few more languages. Regarding looking good and not so good in some of the previews, I had the same experience. But when I submitted it to Amazon, and received the OK, everything went smooth.
Children's books should usually use the fixed layout Kindle format. The InDesign Plugin doesn't do that. The book needs to be hand coded in html and css. It's discussed in Chapter 4 in the Amazon Kindle Publishing Guidelines and on this page: http://www.amazon.com/gp/feature.html?docId=1000729511. You might be able to use the Amazon sample -- there is a link that lets you download the actual files on the page I just linked to -- and modify them to suit your book.
For regular books, I never use the InDesign plugin as I want more control over my ebook formatting. I use the epub output and then convert from epub to mobi using KindleGen. It's actually just as easy and it gives you the opportunity to tweak the html after you output which I like.
@Ellis Home...... Did you use the Kindle plugin and submit your book to Amazon in MOBI format? From what I've read, Amazon doesn't accept MOBI.
