What are the cover options?

Cover Type KDP allows you to choose between a matte or glossy cover. There is no difference in cost. Covers are printed on 80# (220 GSM) white paper stock with either glossy or matte finish:

Glossy finish is shiny. It makes black covers darker and artwork more striking. It's typical for textbooks, children's books, and nonfiction. Matte finish has minimal sheen and a subtle, polished look. It's typical for novels and other fiction.
