Marraii Design FAQ

This FAQ page is a work in progress. At the moment, it’s primarily about book-related topics. It includes answers to the most important questions, but it’s far from finished. New questions are added all the time.

If you need more information about the topics already covered, or you have questions that are unanswered here, please don’t hesitate to contact Marraii Design.


Why should I choose a custom book cover design?

You heard that saying how a picture tells a thousand words. Well, custom book covers tell the story about your book. They are made according to your creative brief, they convey your book’s main topic, and include author-suggested specificities that are crucial for the story. In other words, covers made by Marraii Design are custom-tailored to your book.

Do I need specific software to open epub/mobi?

Yes. You wouldn’t try to open a pdf file in MS Excel, would you? You would use Adobe Reader to view pdf. Likewise, epub and mobi have specific software, apps, and devices that open them. 

  • Computer—to preview epub/mobi on your computer, download Adobe Digital Editions for epubs, and Kindle App for mobi.
  • eReaders—devices with the sole purpose of reading epub/mobi like Kindle Paperwite, Nook Simple Touch, Kobo Touch, and many others. They don’t need installation of specific apps to open epub/mobi respectively.
  • Tablets—devices with more than a reading purpose. They usually require installing apps for reading epub/mobi books that are operating-system-specific (Android or iOS). Those apps are available through the app store, so you can download them to your tablet. To see how, check these sites: KindleApple, Nook, Kobo, Google, Aldiko, Adobe Digital Editions.
  • Smartphones—just like tablets, they need an app to open epub/mobi. See how to get them: KindleApple, Nook, Kobo, Google, Aldiko, Adobe Digital Editions.
  • Apps—there are too many official and third party apps for reading ebooks to list them all. You can search for them and download the ones you want to your tablet, smartphone, or computer. Most bigger retailers offer download of their apps on their sites so that’s the first logical step.

    Check them out: KindleApple, Nook, Kobo, Google, Aldiko, Adobe Digital Editions.

My ebook is enrolled in KDP Select. Can I sell my ebook anywhere else?

No, you can’t sell your ebook version anywhere else (not even on your own site) as long as it is enrolled in Select (90 days minimum).

However, your print version is not bound by such agreement, so you can sell it anywhere you want.

Publishing through Amazon KDP is not the same as enrolling your book into Amazon KDP Select, so if you didn’t enroll your book in Select, you can still publish it everywhere else.

Do you fix epub/mobi files that someone else made for me?

No. Fixing other people’s code in epub/mobi is like looking for a needle in a haystack. That is not offered by Marraii Design. However, if you only have epub/mobi edition of your book, I can use that as a starting point for formatting and coding your book from scratch.

Can I use the file you formatted for Smashwords and upload it on Amazon?

No. Definitely not. There are some differences in how Amazon converts files and how Smash does it. For one, hyperlinked ToC in Smash file does not convert well on Amazon. It does convert well for on-page ToC, but it doesn’t get integrated into “Go To” menu that is essential for Kindle ebooks. 

Why does my book look off in the online previewer?

All online previewers are full of bugs! They rarely display books the way they actually will look like on people’s devices when purchased.

With that being said, here are some of the issues…

Smashwords HTML previewer

Hyperlinked Table of Contents (ToC) doesn’t work in there, nor do any other links. It’s buggy, displays properly formatted text horribly, and your book’s appearance in there is nothing like it is in the actual ebook file.

Smash says that it should not concern you too much because you don’t sell html versions of your book–what previewer file essentially is (this is a quote from their site, not my opinion!). Smashwords doesn’t seem to have any intention of fixing it, so you have no choice but to accept the hard fact–that in best case scenario, your book will be displayed in Arial for all custom paragraph styles and in Times New Roman for normal body style.

There’s absolutely nothing you can do to make it look better.
Your book will be either:

  1. properly formatted, look great to those that buy it, get accepted into Premium, and sell on multiple retailers’ sites, but it will look odd in the previewer,
  2. not properly formatted, break all Smash rules, won’t get accepted into Premium, will look all over the place as epub, won’t sell anywhere, but it will look decent in the previewer.

Amazon Look Inside feature

Amazon’s site has an overriding stylesheet that governs how things appear in the Look Inside feature. No matter what you do in the source file that you upload to Amazon KDP, your book styling will get overridden by Amazon’s site stylesheet. However, the best preview results are gotten by uploading mobi instead of MS Word because mobi is written in HTML, thus looks better when stylesheet override happens. Moreover, the latest Amazon stylesheet even displays custom fonts embedded into mobi! That’s a huge thing compared to what previews used to look like over the years.

Amazon KDP Online Previewer

When you publish via Amazon’s KDP, and check to see how your book looks like using their built-in online previewer tool, have in mind that it has numerous bugs that prevent the previewer from displaying your book correctly (especially with embedded fonts).

Which links are forbidden on Smashwords?

Affiliate Links: If you link to affiliate marketing pages, lead generation pages, and other similar stuff, Smash will close your account without warning due to violation of Terms of Service. 

Competitive Retailer Links: Don’t include links to different ebook retailers in your book. For example, Barnes & Noble will refuse to sell a book that encourages their reader to go to Apple or Amazon for more books.
While it’s okay to link to your Smashwords author profile page, don’t include text such as “Buy my books at Smashwords!”

PDFs: Don’t link to PDFs, because not all e-reading devices may support the PDF format.

Where can I use epub/mobi that you created?
  1. You can upload them to every retailer that accepts epub/mobi files for either sale or conversion to their formats. To mention some: Amazon, Barnes&Noble Nook, Apple iBookstore, Kobo, Lulu, Ingram, Smashwords, Google Play Books, etc.
  2. You can sell them on your website/blog.
  3. You can send them to your readers for reviewing as advanced reader copies, to beta reading group, or to friends and family
  4. You can gift them in giveaways run on your site, social media, other people’s sites and blogs, etc.
What software do you use to make mobi files for Amazon?

Marraii Design hand-codes html files and converts them to mobi with Amazon’s KindleGen app.

Do you make kindle books with Kindle Kid’s Book Creator?

No. Not at this time.

Minimum cover requirements for Smashwords

Smashwords minimum cover requirements:
— flat 2D not 3D
— min size 1400x2100px
— resolution: 72dpi
— with title and author exactly the same as in the book & on Smash profile
— no hyperlinks

Do you embed fonts into epub/mobi?

By default, no. In order to legally embed fonts into ebooks, you have to have a license to do it, and most people don’t have one. 

When you buy a commercial font, in most cases you buy a desktop license, or desktop + web license package. Ebook embedding license is a separate thing that costs extra. Sometimes that cost is quite high, which makes people decide against it.

However, if you have a license to use a commercial or free font in ebooks, then embedding is more than welcome.

Do you format children’s books, graphic novels, screenplays, or fixed format ebooks?

No. Unfortunately, at this time children’s books, graphic novels, screenplays, and fixed formats are not supported.

Cover requirements for Amazon Kindle

The preferred format for the marketing cover is an image of at least 2700 pixels on the longest side and at least 1688 pixels on the shortest side with 300 ppi to ensure image clarity on Kindle HDX devices. The image file size should be 5MB or smaller.

The content of the cover image must not:
– Infringe another publisher’s or artist’s copyright on the same cover.
– Mention pricing or other temporary promotional offers.

Do you offer fixed layout epubs?

No. At this time, Marraii Design only offers reflowable epubs.

Do you use automated conversion software to make ebooks?

No. All Marraii Design epubs and mobis are hand-coded from start to finish (manually written code line-by-line that enables fine tuning).

Smashwords formatting limitations

Other publishing platforms may allow many types of formatting, but Smashwords isn’t one of them! So, whether you’ve seen ebooks look like this or like that, remember—you surely haven’t seen them on Smashwords.

It’s easier to list what Smashwords doesn’t allow than what it does, so here’s a list that includes the most (but not all) things that…

…Smashwords DOESN’T ALLOW:

  • Fonts other than: Times New Roman, Garamond and Arial (with the last two being depreciated)
  • Font size greater than 20pt
  • Use of color or highlights
  • Use of first line indents and paragraph space (either first line paragraph indents or block style paragraph method [space between paragraphs])
  • Tabs
  • Space bar spaces (excessive spaces created by hitting your space bar)
  • Kerning
  • Compressed or expanded fonts
  • Poor covers
  • Tables
  • Columns
  • Text boxes
  • Mixing multiple text or paragraph styles for your body
  • Automatic footnotes and indexes (or automatic anything for that matter)
  • Text wrapped around floating images — only in-line images allowed (above/below text)!
  • Automatic bullets/numbering
  • Drop caps
    (a drop cap is the large initial capped letter you may see in the first paragraph of a chapter in a print book)
  • File size larger than 15Mb
  • Paragraph space before
  • Paragraph space more than 10pt after
  • Line spacing other than single or 1.5
  • Multiple consecutive paragraph returns
  • Section breaks
  • Images other than JPG and PNG
  • High resolution or print quality images
  • Justified text
  • Frequent and/or dramatic font size variations
  • Repeating titles/entries in the Table of Contents
  • Custom symbols (such as é î ® Ω Σ)
  • Headers and Footers
  • Page numbers
  • Other indents besides the “first line”
  • Automatic ToC and Index
  • Multiple conflicting paragraph styles
  • And many others…


  • Not to put the cover inside your manuscript
    (Meatgrinder automatically inserts your cover image into your .epub and .mobi files, so if you do insert the cover image it’ll cause the cover to appear twice in these file formats.)
  • Not to use page sizes other than letter or A4
  • Not to write “Printed in the United States,” because this is your Smashwords ebook, not your print edition. In most cases, your book will fail Smashwords’ manual review and get rejection from Premium.
  • Not to encourage readers to visit a specific retailer to leave a review. “Please remember to leave a review for my ebook at Amazon” –again rejection from Premium
  • It’s not necessary to place your ISBN inside your ebook
  • If the book is also available in a print edition, do not name retailers, just write, “This book is available in print at most online retailers.”

LINKS TO AMAZON – please do not link or refer to any other digital download source other than Smashwords or your personal blog or website. Retail partners don’t want to see links to Amazon, Barnes & Noble, etc., or mention of the Kindle or Nook. You wouldn’t advertise your worst competitor in your book, would you? Well, Apple really doesn’t like to sell books that advertise Amazon, either 😉

AUTOVETTER – is software that inspects your document upon submission for formatting errors according to the Smashwords Style Guide.

PREMIUM CATALOG – is a collection of books that get distributed to major retailers because they meet Smashwords Style Guide requirements.

MEATGRINDER – is software that creates reflowable ebooks that look great on any e-reading device. “Reflowable” means that the text of your ebook will easily flow across all screen sizes, whether your book is read on a small screen like a smartphone, or a larger screen like a tablet. Reflowable books enable your customer to click a button, and instantly enlarge the font size for more comfortable reading.

I have tables that need to look good. Will they convert well on Amazon and Smashwords?

On Smash, no. Smash doesn’t allow tables inside the file. They have to be converted into images or text in both Word and epub. Images, on the other hand, cannot be big so visibility might be an issue. However, epub is still a better choice because, even if tables are not allowed, as images that adapt to screen size they will still look okay.

On Amazon, tables in Word look okay in most cases. When they are bigger, it’s better to have mobi hand-coded with tables set to adapt to screen size which cannot be done in Word.

I have a lot of bullets and numbering. Will they convert well on Amazon and Smashwords?

Nope. At least in 98% of the cases they won’t. Amazon and Smashwords’ conversion systems don’t handle them well. There’s nothing you can do in MS Word to fix that situation. Although it might look okay in some previews of your book, it won’t look okay on most devices, especially smaller ones like smartphones. When you find out—it’ll be too late. That’s why, if you have a lot of lists, it’s best to go with hand-coded epub/mobi that have lists handled perfectly.

My book has a lot of images that are important. Is MS Word formatting the best option for Amazon and/or Smashwords submission?

Not at all. The best option for books with images that need to be of better quality and visibility is hand-coded epub for Smash, and mobi for Amazon. Epub/mobi allow images to be set to adapt to screen size, while that option cannot be set through Word. 

Do I need separate ISBNs for epub and mobi?

Yes. International ISBN Agency says that every format of a book that you sell must have its own ISBN assigned to it.

Most people understand that, if you have a paperback and hardcover edition of your book, you need two separate ISBN numbers–one for each edition. But, when it comes to ebooks, lines get blurred. There’s no such thing as one ISBN number for all ebook formats.

Just like printed formats, ebook formats come in several types, with two of the most important ones being epub and mobi (kindle). Thus, they both require their own ISBN. 

Some publishing platforms don’t require that the files you give them for conversion have ISBN. For instance, Amazon assigns their ASIN number to your ebook, and ISBN is optional. Smashwords offers free ISBN (if you don’t have your own) that you can assign to your ebook. So, if you don’t intend to sell elsewhere, you don’t have to buy your own ISBNs. However, the best practice would be to have one ISBN for each edition of your ebook (one for epub, one for mobi, one for pdf…).

Special Smash notice on ISBN: It’s not necessary to place ISBN inside your ebook, but it is mandatory to attach it to your book via Smashwords’ ISBN Manager feature on your Smashwords dashboard. If you don’t have an ISBN, Smashwords offers one for free. That free ISBN is for epub edition of your book that Smashwords will send to their network of retailers, and it is not for other formats of your ebook that they will generate (such as pdf, mobi, and so on).

What is Smashwords Style Guide?

SMASHWORDS STYLE GUIDE – is a set of formatting rules that must be obliged in order to sell your book through major retailers such as the Apple iBookstore, Barnes & Noble, Sony, Kobo, Diesel, Baker & Taylor and others––via Smashwords. Your book will also be available as a multi-format ebook at

What is Smashwords Meatgrinder?

MEATGRINDER – is software that creates reflowable ebooks that look great on any e-reading device. “Reflowable” means that the text of your ebook will easily flow across all screen sizes, whether your book is read on a small screen like an iPhone or a larger screen like an iPad. Reflowable books enable your customer to click a button and instantly enlarge the font size for more comfortable reading.

What is Smashwords Premium Catalog?

PREMIUM CATALOG – is a collection of books that get distributed to major retailers because they meet Smashwords Style Guide requirements.

What is Smashwords AutoVetter?

AUTOVETTER – is software that inspects your document upon submission for formatting errors according to the Smashwords Style Guide.

You guarantee my book will pass, but are there exceptions?

There are exceptions.

I guarantee your book will pass the AutoVetter on the first run and thus will get into the Premium Catalog, but…if your book is a public domain work, incomplete or partial book, appears elsewhere on the Internet under other authors’ name, your erotica characters are under age, or you write about get­-rich-quick “systems”––there’s nothing I can do to make your book enter the Premium Catalog!

If my ebook cannot look exactly like my print edition, why bother?

By giving up control over the fixed layout that you have in a printed book, you gain a lot more with reflowability of an ebook. Instead of making your book accessible to only those that read printed books, you’re making your book accessible to millions of potential readers all over the world that prefer digital.

What file formats will I get for my cover?

Your ebook cover will be delivered as high resolution JPG and PNG. Your print book cover will be delivered as a print-ready PDF.

Will I get source files for my cover?

Marraii Design can provide a layered PSD upon request.

Do you create fonts for covers?

No. Font design requires special skills and software that Marraii Design does not possess.

Is there a limit to the number of stock images you use?

Yes. The cost of stock images used in a cover design cannot exceed the price paid for the cover itself.

What kind of images you don’t use?

Marraii Design never uses images from Google search, images found on other people’s blogs/sites, desktop wallpapers, or clipart from random websites.

Will you send me those images along with the final cover design?

No. You are buying the final product—your brand new cover design that is a result of Marraii Design’s creative work. You’re not buying individual images purchased on stock sites for the purpose of creating your cover. However, you will be given links to those images on their respective stock sites, so you will be able to buy them if you need them separately. Have in mind that those source images, in their original form, might look quite differently than they do on your cover because they will have undergone a big makeover.

Is the cost of stock images included in the cover design price?

Yes. All photo expenses are included in the price.

Where do you get images for your cover designs?

Marraii Design uses licensed stock images form:

  • trusted websites like,,, and similar
  • free stock images and public domain images from verified websites like or Wikimedia Commons.
Can I send you my own photos?

Yes, but make sure you own the rights to use them, that they are big enough, and high enough in resolution (300dpi for print).

What is a mobi?

Mobi format was purchased by Amazon from its developers, and used to develop the Kindle. Meanwhile, Amazon has added some new and improved formats like KF8, but .mobi is still the best source file to upload on Amazon. It can be read on any of the Kindle devices and Kindle Apps. 

When you receive a .mobi file from Marraii, it actually has three parts packed in it: a HTML file used as the basis for the file; a KF8 file for the more-advanced devices, and a KF7 file for the older Kindle devices.


What’s an ePub?

ePub ebook format is an industry-wide standard for eBooks. It is the most common eBook format used on the market. It can be read on most eBook devices, except Kindle.

There are two epub formats: epub2 and epub3. Marraii Design offers only epub2 creation until epub3 becomes widely acceptable (which it’s still not). ePub2 is the most common format for sale on the market and all of the retailers accept them (Amazon accepts epub2 as a source file for conversion, but not as a stand-alone selling format).
