QUICK AND HANDY GUIDE
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.
