eBook Cover Specification

If you are providing your own eBook cover image file, please follow these guidelines:

  • RGB, not CMYK
  • JPG, PNG, TIF or PDF file formats
  • Recommended size is 2560 pixels on the longest side and 1600 pixels on the shortest side (minimum of 1200 pixels)
  • Generally a width:height ratio of 1:1.6 is suitable
  • A file size of under 1MB is recommended if you are distributing via Amazon, as they include the cover file size when calculating download fees
Please note:
  • If you are supplying an ePUB to us for distribution to Apple, any images (including the cover) contained within the ePUB must be less than 3 million pixels. To calculate the pixel size multiply the height in pixels by the width in pixels.
  • We do not usually include a back cover
  • Do not include a bar code or price information
  • Some retailers will reject a book if the title and author name on the cover do not match those provided as metadata
