Guide to Kindle Worlds Content Quality

Content published though Kindle Worlds is held to the high standards customers have come to expect from Amazon. If readers tell us about a problem they’ve found in your story, we will make sure you know about it and point you in the right direction to get the problem fixed.

The information listed here will help you understand the types of quality issues we see most frequently, and will give you an idea of what you should be paying close attention to when building your manuscript.

Identifying Errors

It is very important to search your manuscript for errors before uploading the original file or prior to uploading a new file after fixing problems post-publication.

Some errors cause a story to be incomplete or unusable. We refer to these as Critical Issues. Because Critical Issues significantly impact the reading experience, any Critical Issue will result in the story being removed from sale until the correction is made.

Reviewing Your Manuscript

When you review your manuscript for quality issues, we highly recommend that you use Kindle Previewer. This free program will allow you to preview how your file will look on various Kindle devices and apps. If you are using Microsoft Word to build your manuscript, be sure to check out our Design Guide for Kindle Worlds Stories for tips, tricks, and advice on formatting a manuscript.


Typos are among the most common quality issues customers report. In order to produce a high quality ebook, please do your best to ensure your manuscript is free of typos. Typos may be caused by a variety of issues: mistyped words, poor optical character recognition for scanned texts, copy/pasting across source documents, or multiple conversions of a source file. Here are some examples of common typos:

Example Type: Example: Should be:
Numbers in place of letters 5arasota Sarasota
Incorrect punctuation The dog ran, The dog ran
Letters in place of numbers 1o66 1066
Soft Hyphens re-peat repeat
Missing letter Nothi g Nothing
HTML tags in place of characters < sup >® ; ®
Junk characters •”gainst Against

Fixing and Preventing Typos

If a typo is present in your manuscript, it is important to search for the term throughout the text. It is also important to review your text for errors of a similar nature. The search function of Kindle Previewer can be very helpful for locating and fixing all instances of a repeated typo.

Sometimes improper or dialectic spellings are intentionally used by the author. These are not considered errors. Common examples would include character dialogue. Spelling differences which occur between US and British English are not considered errors.

Unsupported Characters

If your text appears in Kindle Previewer as either strings of jumbled characters or boxed question marks, this usually means your text contains an unsupported accent mark or character. To ensure your manuscript does not have any unsupported characters, review your manuscript in Kindle Previewer and look for square boxes or jumbled characters like these:

Preventing and Fixing Unsupported Characters

If an unsupported character is present in your manuscript, it is important to look for this issue throughout the text, as one unsupported character is usually indicative of others. Use the search function of Kindle Previewer to locate all instances of an unsupported character.


Formatting issues occur on the visual or layout level of a title and include problems such as extra spacing between paragraphs or forced text justification. Formatting errors in your manuscript may prevent readers from customizing their reading experience to their preferences, and also may include issues that cause text flow to be unintelligible or confusing.

In order to produce a high quality story, please do your best to ensure your manuscript has proper formatting. An effective way to do this is by viewing your manuscript with Kindle Previewer. This tool can help you identify formatting errors before submitting for publication.

Ensuring Correct Formatting

Please see the Design Guide for Kindle Worlds Stories for tips on building a well-formatted manuscript. Check throughout your manuscript for similar issues because recurring formatting errors tend to occur throughout the text—for example, incorrectly set left or right margins would appear on each page.

Critical Issues

• Body text rendered as bold, italicized, underlined or hyperlinked text
• Extra body text margin padding that is more than 1/4 of a screen wide
• Primary content is oriented in landscape mode without any detail page disclaimer
• Body text not set to default color
• Forced white text or forced black background that causes text to be unreadable. For example, forcing a code such as Font = white will cause text to be unreadable while reading on a white background mode or on an e-ink device.
• In-line page numbering is present

Page numbers entered within the manuscript file break the flow of the reading experience and must be removed.

Here are some examples of other formatting issues:

• Forced alignment of body text
• The size of the body text is forced, causing it to be larger or smaller than standard text sizes
• Body text incorrectly changes size
• Bullet points missing from a bulleted list
• A list has bullets which appear on a different line that the list contents
• Missing list formatting

A best practice is to preserve the reader’s customizable reading experience by not forcing formatting for text.

Note: Lists without proper formatting can be unintelligible to the reader.

• Incorrectly added line break
• Missing indication of paragraph separation (indentation or single line spacing between paragraphs)
• Missing line break that indicates a section or scene change
• A hard page break in the middle of a section or chapter
• Extract or block quote not differentiated from body text

Note: Additional or missing breaks may confuse the reader and break narrative flow.

• Sidebar text interrupts a sentence, paragraph, or section
• A footnote interrupts a sentence, paragraph, or section
• An image interrupts a sentence or paragraph.

Note: Improperly inserted sidebars, footnotes, or images can fragment the reading experience, leading to confusion.

• Extra body text margin padding that is less than 1/4 of a screen wide
• Double spacing between each paragraph
• Consistent incorrectly added line padding between section/chapter headings and first paragraphs

Note: Readers should set their own reading preferences and not have to page forward more than needed.

• Split monograms; the first letter of each chapter in your manuscript should appear on the same line as the rest of the word.
• Individual paragraph incorrectly rendered as bold, italicized, underlined or hyperlinked text
• Forced black text or forced white background that causes text to be unreadable. For example, forcing a code such as Font = black will cause text to be unreadable while reading on a black background mode on a color device.


All links in your manuscript should navigate correctly to the place where the reader would expect them to go, and the user should be able to navigate to the guide items in your story. Please test links, including guide items, on your Kindle device to ensure the links in your story navigate to their intended places before submitting your manuscript. If you don’t have access to a device, Kindle Previewer is a helpful tool that will reproduce how content will appear on a device.

Preventing Linking Issues
Broken or incorrect links usually occur when a mistake has been made in the link URL or an incorrect link location has been pasted in. Check the HTML or inserted links in your text to correct this problem. Below are some examples of linking issues.

• A guide item that does not work—a guide item is the navigational locations that readers can access from the ‘Go To’ menu
• A link in the Table of Contents (ToC) that does not work
• An unlinked footnote
• A prohibited external link
• An external link that does not work
• An internal link (ToC, NCX, & other) that does not link to the correct location
• Reference to an unlinked page number
• Missing Table of Contents
• Missing NCX

Table Errors

A common complaint we receive about tables is that part of the table is being cut off, which usually happens when tables are used for formatting non-tabular data (e.g., sidebars, lists, large chunks of text, etc.). It’s best to avoid using tables to format text or to try to make text elements appear in a certain way.

Critical Issues

• Each table with content cut off at bottom of screen when viewed at font size 3 (the default)

Note: This causes content to be inaccessible for the majority of readers.

Below are some other tables issues we see:

• A table that consists of non-tabular data
• A table that requires the user to pan right over non-tabular data

Note: Tables with non-tabular data often force readers to take additional action to be able to read plain text content.

• A table with forced line breaks
• A table with a word in a cell split across 2 or more lines

If the data absolutely must be displayed in tabular form and you still see the error, try breaking it up into more cells so that there are more available break points.

The Previewer and Kindle for PC will not always reproduce table display very accurately. If possible, make sure to check table formatting on a Kindle device, especially if it appears to be a critical issue.

Duplicated Text

This refers to any text which repeats in the manuscript when it is not intended to repeat. Usually this is the result of a copy-paste error, and can be fixed by removing the duplicated text.

Critical Issues

• A repeated chapter that is also mislabeled

Other duplicate text issues include:

• A repeated chapter
• A portion of text that is repeated within a chapter or section, excluding single words

Wrong Content

Stories with wrong content are always removed from sale.

Wrong content occurs when a customer receives something other than what is advertised. This is most commonly caused by uploading an incorrect file, but can sometimes also occur if updates are made to the product information or copy/paste issues make the description incorrect. The easiest way to fix it is to upload the latest version of the correct file.

Content Unsuited for Reading on Kindle

Content that is not suited for Kindle are removed from sale.

Some stories are simply not well suited to the Kindle format. These include any kind of story where the main purpose is to allow the reader to write or color on the pages. These are better suited to publishing in a physical form. Examples of stories not suited to the Kindle format include the following:

• Puzzle books
• Blank Journals
• Pattern books
• Coloring books
• Facing page translations (left page in one language, right page is same content in another language)
