What is the minimum page count?
For KDP Paperbacks, you need at least 79 pages to have text on the spine. If it's fewer, the spine will be too narrow to print cleanly.
How is spine width calculated?
For white paper (most common), calculate Page Count * 0.002252 inches. Cream paper is slightly thicker (0.0025 inches per page).
