eBook Cover Sizes Different Sites

ALL LINKS LAST CHECKED 27 February 2017.  PLEASE NOTIFY ME IF YOU ARE AWARE OF ANY NEW CHANGES.  (ebook.indie.covers@gmail.com)

SMASHWORDS

File Size         –  Not stated, though it is mentioned the entire ebook should not be more than 5 MB
Dimensions  –  Minimum width of 1400 pixels.  Recommended size APPROXIMATELY 1:1.5 ratio or 1600 pixels by 2400 pixels
Resolution   –  Not specified

From their FAQ:

What are the requirements for my cover image, and how do I create one?
In mid-2012, Smashwords increased the dimensional requirements of ebook covers to satisfy the recommendations of Apple and Barnes & Noble.  The new requirements, along with visual examples, can be found by clicking here to the Smashwords Blog.  Book covers must be uploaded as image files (files that end with .jpeg, .jpg or .png), not as PDFs for Word documents, and must include the book title and the author name. The cover should show the front of your book only, not the back cover you use for print. It must be two-dimensional, not 3D or pseudo-3D.

Cover images must not contain web addresses on the front cover (some retailers will reject them for this reason) or promises of products not included in the book (such as, “Comes with a free CD!”). They should be vertical rectangle-shaped (the height is greater than the width), not squares, and must be a minimum width of 1,400 pixels. A recommended size is approximately 1,600 pixels wide by 2,400 pixels tall (the proportions of most paperback books in the USA, which have height 1.5 times greater than their width). To view the pixel dimensions, right mouse click on the image and click properties. There’s room for personal preference.  Aim to make the height approximately 30-60% greater than the width and the book should look good.  When Smashwords or our retail partners receive your cover, it will often be converted to multiple smaller sizes, so don’t make your title text or author name too small, otherwise it’ll be unreadable when it’s shrunk down to thumbnail size.

KOBO

File Size         –  Should not be more than 5 MB
Dimensions   –   Not specified though they recommend a 1:1.35 ratio.
Resolution     –  300 ppi

Below is a paragraph from their Writinglife Guide.

Select a .jpg or .png file. Note: For best results, we recommend your image should be 300 DPI and no larger than 5 MB. If you are creating your own images, keep in mind that the standard Kobo eReader has a 1448 by 1072 resolution with 300 pixels per inch screen. This is a good resolution to shoot for.

KINDLE DIRECT PUBLISHING (Amazon)

File Size         –  Less than 50 MB
Dimensions  –   Minimum of 1000 pixels on the longest side, ideally 2500 pixels on the longest side and height/width ratio of 1.6
Resolution    –   Not specified

From their Publishing Help section:

Kindle Direct Publishing currently accepts two types of files for cover images:

  • JPEG (JPEG / JPG)
  • TIFF (TIF / TIFF)

We apply additional compression to images when displaying them on the website. For best results, please upload your images with minimal compression.

Dimensions

The ideal size of your cover art is a height/width ratio of 1.6:1. In pixels, this means that, for every 1,000 pixels in width, the image should be 1,600 pixels in height. To ensure the best quality for your image, particularly on high definition devices, the height of the image should be at least 2,500 pixels.

Ideal dimensions for cover files are 2,560 x 1,600.

Important: The minimum image size allowed is 1,000 x 625 pixels. The maximum image size allowed is 10,000 x 10,000 pixels and your image must be less than 50M.

Size

Your cover image must be less than 50MB. Try to avoid compressing your files, as this can affect the quality of your cover when displayed on reading devices. We recommend saving your file with a minimum of 72 dots per inch (DPI).

Color

Product images display on the Amazon website using the RGB (red, green, blue) color mode or profile. RGB is the color mode native to the web and many color screen displays, as these three colors displayed at varying levels of intensity create over 16 million colors. When saving and uploading your cover image file, save your file ONLY as RGB – not CMYK or sRGB- for the color profile. You can usually find this option in the File saving dialog of image manipulation programs such as Photoshop.

Some programs may also refer to RGB color as ‘True Color’ in some programs. If in doubt, try opening a JPG inside Internet Explorer, Firefox, or Safari. If a JPG opens fine inside a web browser, it’s most likely okay to use as a cover image.

Make sure to save your image without color separation. This is usually a pre-press or color palette option. Use your image manipulation program or image analysis tool (some are available free online) to verify that your image file doesn’t have color separation.

Use color images whenever possible and relevant. In addition to the Kindle black and white E Ink reading devices, customers can read your books on full color Fire devices and free Kindle reading apps for iPhone, iPad, Android, PC or Mac.

DRAFT2DIGITAL

File Size         –   Not specified
Dimensions  –   1600 x 2400
Resolution    –   Not specified

From their FAQ:   What are your cover art requirements? For best results, give us a JPEG at 1600×2400. But really, all we need is a tall rectangle. We’ll accept most standard image formats, and resize whatever you upload to meet the requirements of the sales channels you choose.

APPLE iBOOKS

File Size         –  Not Specified

Resolution    –  Not specified

BARNES AND NOBLE

From the support pages of Nookpress.com:

https://www.nookpress.com/support/faq

Upload your cover image file for your NOOK Book from the Cover Image page. Your cover image must be a .jpg or .png file with a file size between 5 KB and 2 MB, and the height and width must be at least 750 pixels. However, for optimum quality, we recommend that both the height and width are at least 1400 pixels. If your cover image does not meet these specifications, then you must use image-editing software to stretch or shrink the image. Remember, you must have the rights to use any image that you upload.

LULU

This site is an exception and has wider and smaller covers compared to others: Here I found the exact requirements on their site: “You will need to upload a full size cover image. 612 x 792 pixels (8.5” x 11”, 72 DPI) is preferred to avoid blurriness.  Check all images, including your cover, before you upload to make sure the images are readable and don’t contain obvious pixelation. Your cover art should perfectly fit the available space/frame of the image area. Otherwise, the cover tool will add white borders around your image, making it appear small or incomplete. 3D images of a book, screenshots, or images of a printed version of the book for your cover will also be rejected.” (Point Number 7 in this article on the Lulu.com site).
