Adding a KDP hardcover to your paperback: trim sizes, page limits, margins, the hardcover cover template, print cost and whether it pays.
Hardcover from paperback
A hardcover template is not a bigger paperback one. Art runs 0.51 inch past the front edge, text sits 0.635 inch in, and a 0.4 inch hinge by the spine stays empty.

On Amazon.com, black ink at a regular trim is a flat $6.80 from 75 to 108 pages. A 300-page 6 x 9 hardcover costs $9.25 to print, $4.65 more than the paperback.

Hardcover margins follow the paperback table: gutter 0.375 inch up to 150 pages, 0.5 to 300, 0.625 to 500, 0.75 to 550. Outside margins are at least 0.25 inch.

A hardcover pays off when you already have a paperback at a hardcover trim, 75 to 550 pages, and room for a higher price. At $24.99 a 300-page 6 x 9 earns $5.74.
