Formatting Checklist for Self-publishing on Amazon KDP and Smashwords
02/02/2018
There’s lots of information out there on self-publishing from a number of angles. The publishing process, the design, the marketing… How do you know what format is required for each publisher?
I’ve admittedly not spent vast amounts of time looking, but haven’t found a definitive source on how to get all the correct formats for your self-published books – this post is an attempt to do that.
First, some background. I wanted to self-publish a non-fiction Cyber Security book. Some preliminary research suggested I should look at two online stores: Amazon KDP (Kindle Direct Print) and Smashwords.

Print, eBooks, Quill…
Surely things were easier when we had paper and pen?
KDP means your book will be published on Amazon, which accounts for the vast majority of eBook sales. You can either:
- Publish a Kindle eBook on Amazon – this can be downloaded directly to a Kindle reader
- Publish a physical book on Amazon – this will be printed
by Amazon and posted to the customer - Publish both – Amazon will link the books to their store and a customer can decide what format they’d like to buy
Smashwords is another online bookstore, they will:
- Publish your book on their Smashwords store – this can be downloaded in a variety of eBook formats, such as:
- Kindle – this may seem a little confusing, but Smashwords will make the book available in a Kindle format so a reader can download it and (manually) send it to their Kindle
- ePub – a common eBook format
- PDF – a common computer reader format
- Others, such as text or HTML, e.g. directly on a web page (these don’t tend to look too good)
- Distribute your book (subject to it being in the right format) to:
- Apple iBooks
-
- Kobo
- Barnes and Noble
- Many, many more…
It seems like perfect sense to have both KDP and Smashwords publish your book. There is a gotcha however…
In short, I used both Amazon KDP (non-Select) both eBook and Print, and Smashwords (so three in total), and I wanted to publish it for FREE.
Now for the formatting and pricing challenges. By formatting, I mean what type of files should be used to send to both KDP and Smashwords. Everyone’s generally heard of DOCX or PDF, but in the self-publishing world, it’s not that straightforward. Let’s begin:
At a minimum, you will need a manuscript, e.g. the content, and a cover (Amazon will let you pick from some stock images, but using your own looks more professional).

Be careful when selecting your colour space. RGB vs CMYK can make all the difference.
The manuscript:
You can use .DOCX
You can also download Kindle Create, which will help you perform all the formatting: https://kdp.amazon.com/en_US/help/topic/GHU4YEWXQGNLU94T
The cover:
This MUST be in either JPG or TIFF format and is a single page (this is different from KDP Print which needs a front and back cover). Information on the dimensions on the front cover can be found here: https://kdp.amazon.com/en_US/help/topic/G200645690
I am advised by the excellent people at Windswept Marketing and Design (https://www.windswept.co.nz/) that digital formats are best saved in the RGB
The price:
All books on Amazon KDP must be a minimum of £0.99p (other countries vary). If you want to publish your eBook for free, follow this handy blog here.
Amazon KDP Print
The manuscript:
This must be in PDF format. There are also specific formatting rules to follow: https://kdp.amazon.com/en_US/help/topic/G202145400
The cover:
This must be in PDF and must be front and back
There are specific guidelines to follow for sizing, and also if you want text on the spine of your book. If you want this, your book needs to be 100 pages long so the spine if big enough to fit text on. More information here: https://kdp.amazon.com/en_US/help/topic/G201834210
The price:
Amazon will print the book for you and will give you options of how you want the print, e.g. matte or glossy cover, page size

The manuscript:

Smashwords has a very specific set of formatting rules – far too complex to go into here. More information can be found
The cover:
A single page cover in a JPG or PNG format. It should be in RGB format. More information here: http://blog.smashwords.com/2012/06/new-ebook-cover-image-requirements.html
The price:
Smashwords allows you to publish for free or at a cost you decide.
Additional:
When you publish, Smashwords will enter your book into their Premium Catalogue which means it will be sent to iBooks, Kobo, etc – you need to ensure all the formatting is spot on, or it will be rejected.
In summary, if you want to print to all KDP, KDP Print and Smashwords you will need:
- A manuscript in DOCX and PDF formats
- A single cover in JPG format (RGB
colour space) - A front and back cover in PDF (CMYK
colour space)
It’s also worth thinking about the following in advance too:
- Author Name
- Book title
- Book subtitle (optional)
- Book series, e.g. if the book is part of a trilogy or non-fiction series, you might want to highlight it.
- Book short summary
- Book long summary
- Book keywords, e.g. words that will help people search for your book (think of around eight), e.g. sci-fi, futuristic, etc
- Book category – this is generally a chain of categories, e.g. non-fiction, computers, computer security
- Book pricing
Here’s a summary table:
KDP eBook | KDP Print | Smashwords | |
Manuscript | DOCX, PDF, MOBI, etc | DOCX | |
Cover Pages | Front Only | Front and Back | Front Only |
Cover format | JPG or TIFF | JPG or PNG | |
Cover Colour space | RGB | CMYK | RGB |
Pricing | Free if price matched | Printing costs plus author royalties | Possible to sell for free |
There’s plenty more to this subject, and I’ll keep the blog updated as I learn more myself.
I’m reading this on iPhone using safari private mode and noticed a lot of formatting inconsistencies… smashing play there Mr Perry ! Love it.
Hopefully all fixed now. Thanks for pointing them out…!
