Currently, each minted asset can have only one cover.
Book.io/Stuff.io requires that each minted asset includes a high-resolution cover image with dimensions of 4000 x 4000 pixels to ensure optimal quality and visual appeal. This 4K resolution standard guarantees that the cover art is displayed crisply across various devices and platforms. You can create a full 4000 x 4000 image or use the Book.io / Stuff.io Photoshop (.psd) files below to add borders and branding to your cover.
Dimensions: 4000 x 4000
File Type: jpg or png
If you have a tall or wide image, such as a standard ebook cover, or prefer Book.io/Stuff.io branding (Borders), please use the Photoshop templates below.
