What you need for a book cover
You also need to know what size and company you are printing through as they all have different requirements.
These covers are all different. Even from paperback to hardcover. Different page counts too, which for Ingramspark and Lulu have to be exact page counts.
Amazon gives you a few pages to be off but if your page count is off you can end up with spine errors.
Page counts include ALL pages. (See Below)
Ingrams requires all that space around the cover for the best printing. That space has your ISBN and what type of book you are printing. If that information doesn't match your Ingram account they won't print the book.
My Beef with Lulu! They won't tell you the cover size or give you a template until you upload the interior. This is good as you can't get the wrong size. This is bad as you have to go step by step rather than doing the interior and cover at the same time.
INGRAM SPARKS DIRECTIONS!
Easiest: Get your ISBN and load all the meta book data to Ingrams FIRST otherwise you will do it twice and if the information doesn't match it's a pain to change.
