Children's Picture Book

I don't understand how a children's picture book can be created with the following restrictions:

*600x800 pixels
*highest resolution possible (really?)
*127kb total image size limit

What am I not understanding? With these restrictions, the best I can get is a 2"x2" (approx) image for a full color (RGB) illustration.

Also, what is the file size limit for the final ebook?

Thanks in advance!

The max size for a Kindle ebook is 50 MB, but that will cost a Ton of download Fees!

50 mbX $0.15/MB= $7.50 in download!

This leves you $2.49 to split 70/30 with amazon on a $9.99 book!

Don't worr much about dpi fo with the 600X800 pixel size and try to keep the total image down to around 200KB

Thank you very much for your help.

I do not know about the download fee, I have three ebooks on kindle right now (text) and I'm not aware of the download fee, can you explain?

I spoke with Adobe support today, and was told that the largest ebook (not kindle) file size is 500MB! I assume there is a download fee for those formats as well?

So it is okay to use 72dpi for the images? That would solve my problem, but I read somewhere to use the highest resolution possible(!?).

Thanks again!

The typical" Story Book" only costs about 6 or 7 cnets to download so it isn't a biggie!

The 70% royalty the fee comes out then the split

for the 35% royalty Amazon pays the delivery, but in big books there is a minimum price!

I don't know the min for a 50 mb one

Thank you for answering my question about download fees!

Can someone please answer my question about image file size limit?

The documentation on the site says 127KB limit on image files, but an answer that I just received after waiting over 24 hours says "Further, you may upload content with images with high resolution and successfully publish the same on the KDP web site. We do not have size specifications for images within the content of your title."

Thank you in advance for your help.

While the official Kindle Publishing Guidelines specify a maximum internal size of 127kb, this is neither strictly true nor does it make much sense. When your book is converted to Kindle using one of Amazon's processes (KindleGen, Kindle Previewer, or the KDP website) images will be automatically resampled and/or recompressed as necessary to meet the requirements for publication. In my testing most images will end up in the neighborhood of 128kb, with the largest appearing to be around 160-170kb. This limit is apparently quite a bit higher than 128kb for fixed-layout books, but I have not done extensive enough testing myself to tell you how large that practical limit is, nor whether the 800kb figure given in the Publishing Guidelines is at all accurate.

I would suggest including your images at a reasonable final resolution in JPEG format, saved at the highest quality possible. After the book has been converted give it a thorough review on as many Kindle readers as possible to see if the results are satisfactory. You will likely find that they are, but if they are not you can then investigate strategies for manually optimizing them further.

Above all, test, test, test, and test some more. This will always be the best way to be sure. Kindle Previewer is very handy for this testing as it can convert your content from HTML to a compiled Kindle eBook and give you an immediate preview of the results.

Thank you very much! This makes much more sense. I'm going to keep my images at 100dpi, but there's no way I'm going to come close to the 800KB restriction. I'll report back what happens.

Why does kindle have such terrible technical support? Are they selling conversion services, like createspace does? And even if they are selling services, they should offer technical support. createspace offers excellent support, you can even speak with someone on the phone, 24/7.

If kindle isn't selling conversion services, their company blueprint is flawed. I suppose they don't care because they're making lots o' money with the flawed plan.

My book was about 30 MB before I uploaded it to Kindle. However, somewhere in the file conversion process, the total file size was reduced to 1.9 MB.

I think the limitation of 50 MB is for your original, unprocessed word doc, or whatever format you use. Actual Kindle book size will be much less, and they will inform you of how big your converted file is.
