Ebook Cover Design and Optimum Size Specifications for Amazon, Kindle, B&N, Nook, iBookstore, and iPad Formats


All images should be RGB and not CMYK. Lulu will reject sRGB, if you want to use them to get into the iBookstore, but other retailers accept it.

Again, always go for the correct file size first, at the cost of resolution if necessary; not the other way around.

  • EC = Embedded Cover (give to ebook formatter to embed)
  • CC = Catalog Cover (you’ll upload separate from ebook)
  • n/s = Not Specified
Format Size in px Resolution File Size
Kindle CC JPG, TIFF min 500px max 1280px 72 dpi n/s
Kindle EC JPG 600 x 800 167ppi – 300dpi 127kb
B&N/Nook CC JPG, GIF, PNG 600 x 730 n/s n/s
B&N/Nook EC JPG, GIF, PNG 600 x 1024 170 ppi 300kb
iPad EC JPG, GIF, PNG 600 x 860 132 ppi 200kb

Again, 600px x 800px will pretty much cover your bases, so if you choose one size, I suggest that one.
