Be sure that once your book cover had been designed and ready for the printer, that you receive a jpg image of your finished cover… several in fact. One at 300dpi final book size, if your book is 5.5″ x 8.5″ then that is the size of this jpg. From this image all other images for use on your website or for advertising can be made.
Each specific use will have a specific size and dpi requirement.
- Most images used on a website are 72dpi and can vary in size.
- Thumbnails are usually about 1-2 inches wide.
- Online book distribution and sales services need the image for your book page.
- And you’ll need a 300dpi image for all your catalog and promotional materials.
Some designers supply a 3D book cover image (like the one at the beginning of this paragraph), this image gives the appearance of a ‘real’ book in that it is standing and shows depth with a spine and pages. This type of image is good for any book flyers, postcards and sales pages. Be sure to have it made at 300dpi for best use reproduction.
