Cover Image Guidelines 3.2
3.2.1 Cover Image Guideline #1: Marketing Cover Image Is Mandatory
Kindle books must have a marketing cover image provided for use on the website detail page. The
preferred format for the marketing cover is an image of 2560 pixels on the longest side and 1600 pixels
on the shortest side with 350 dpi to ensure image clarity on Kindle HDX devices. The image file size
should be 5MB or smaller.
If the marketing cover image size is smaller than the 2560 x 1600 recommendation, a reminder message
is displayed at time of upload. Covers with less than 500 pixels on the smaller side are not displayed on
the website.
If your cover image is smaller than the recommended size, Amazon strongly recommends that you create
a new image that meets the size requirements. Do not stretch the image to meet the size requirements,
because this may lower the image quality.
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.
3.2.2 Cover Image Guideline #2: Internal Content Cover Image Is Mandatory
Kindle books must have an internal cover image provided for use within the book content. Provide a
large, high-resolution cover, because Amazon quality assurance will fail the book if the cover is too small.
Define covers in the OPF file using either of the following methods (underlined elements are mandatory):
Method 1 (preferred):
<manifest>
...
<item id="cimage" media-type="image/jpeg" href="other_cover.jpg" properties="cover-
image"/>
...
</manifest>
This syntax is part of IDPF 3.0 standard and described at http://idpf.org/epub/30/spec/epub30-
publications-20111011.html#sec-item-property-values.
