Most aggregators require a book cover of a minimum size of 1600 x 2400 pixels.


  1. You cannot really enlarge a very small image that much, it will become pixelated and look terrible. This option is more to make a very large image smaller!
  2. Make use that you maintain the aspect ratio or else your image will look lopsided.
