Book Cover Specifications
  • Please include the title and author in the cover. If there is no author, you will need to include the publisher. The category is sent only as a reference and should not appear in the cover.
  • Please make the title big enough, most of our readers use very small screens to access our app.
  • Size: 480 px x 720 px /150 dpi (.jpg)
  • Photos: If you use photos, make sure that they are copyright free or under Creative Commons CC0. You can find photographs with those characteristics here. You can also take a look at our Photo Library (in progress).


Thank you for sharing your cover with us - what we do could not be possible without volunteers like you who believe in a world full of books, for everyone.
